We have a new glaucoma (eye pressure) test that is considered much more accurate than the “air puff test”. There is no sensation, no eye drops, AND it can be used over soft contact lenses. Now everyone can experience no fear about getting the eye pressure test!
Teenagers (and the parents who love them) often ask us about switching from eyeglasses to contact lenses. Whether the change is permanent or just an alternative to glasses, there are several great reasons for getting your teen into prescription contacts.
- Freedom: Your teen may simply be tired of wearing eyeglasses, especially thick frames that slip and slide down the bridge of his or her nose.
- Sports: Glasses don’t mix well with active sports. They can fall off. Even worse, they can break, leading to injury. Repairing or replacing broken glasses is also costly. And glasses don’t provide the peripheral vision needed during game play. The good news is that quality contact lenses solve those problems. They make it easier to wear protective goggles, too.
- Glasses-free look: Remember your teen years? Were they awkward or smooth sailing? Maybe a mix of both! In any case, your teen may simply prefer the way he or she looks and feels without glasses.
- Eye color change: Today’s natural–looking color contacts are very popular among teens. And they’re safe–so long as they’re prescribed by an eye care professional.
Talking About Contacts With Your Teen: Important Topics
Contacts are medical devices. Did you know that contact lenses are considered medical devices? It’s easy to understand why. The eyes are one of the body’s most important and delicate parts. That’s why what we put in and on them must be medically safe and properly fitted by an eye care professional.
Wash your hands before handling and inserting your contact lenses. Your eyes are one of your immune system’s most vulnerable points. To help keep germs away and protect your vision, follow the hand washing instructions from your eye care professional.
Handle your lenses with care. Contact lenses can tear. Never wear torn contact lenses. They can scratch your eyes leading to infection and other possible vision problems.
Consider daily disposable contacts. Clean contact lenses are key to helping keep your eyes healthy. Daily disposable lenses or “dailies” are worn for the day and thrown away before going to sleep. They offer several benefits:
- No nighttime lens cleaning required, saving time and cleaning solution. (Particularly beneficial for teens that may forget to clean their contacts or ignore the process.)
- An easy–to–remember wear schedule.
- They can help people with eye allergies. Starting every day with a fresh pair of lenses means there’s less time for allergies to flair and deposits to build up.
- They offer a self–esteem boost in helping teens succeed with their new responsibility.
Don’t share your contacts–ever! Your contact lenses are fitted and prescribed just for your eyes. Sharing contact lenses can encourage an eye infection and other vision problems.
A special caution about Halloween contact lenses. Like color contacts, novelty contact lenses are popular, especially for Halloween. As we mentioned earlier, it’s essential to have contact lenses of any kind properly fitted by an eye care professional. In fact, some lenses may not be FDA approved unless they’re purchased from a licensed professional. Wearing contacts that aren’t fitted and prescribed by a professional could harm your teen’s eyes.
If you’d like to schedule an appointment to fit your teen for contacts, or to learn more about them, please give us a call.

Most of us are familiar with the term “20/20 vision” and know it means our eyesight is pretty good.
But what exactly does “20/20” mean? Is it possible to have vision that’s better than 20/20? Is it safe to drive if you don’t have 20/20 vision? And what does it mean if your vision is 20/40? Or 20/200?
Also, can you have 20/20 eyesight and still have vision problems? (Spoiler alert: The answer is “yes.”)
It All Started With an Eye Chart
In 1862, a Dutch eye doctor named Hermann Snellen devised an eye chart that became the standardized way eye care professionals to this day determine a person’s distance visual acuity–how clearly someone sees distant objects.
The traditional Snellen eye chart has a single large block letter (usually an “E”) on the top of the chart, and 10 subsequent lines of progressively smaller block letters. Each line has more letters than the previous line to keep spacing between the letters relatively uniform.
By experimentation, Snellen determined the smallest letters a person with “normal” vision could consistently identify correctly. This became the 20/20 line on the chart. In other words, if you can correctly identify letters of this size on the eye chart (but none smaller) from a testing distance of 20 feet, you have normal (or “20/20”) vision.
Since the standard testing distance for the Snellen chart used in the United States is 20 feet, the top number in the Snellen fraction is always “20.” The bottom number varies, depending on the size of the letters on each row of the chart.
Here’s how it works
Three lines above the 20/20 line on the Snellen chart, the letters are twice as large as those on the 20/20 line. A person with normal visual acuity therefore can be expected to correctly identify these larger letters from a viewing distance that is roughly twice that of the normal testing distance of 20 feet (so, 40 feet).
If this line is the smallest line of letters a person can correctly identify at the normal testing distance, he or she has “20/40” vision–this is the smallest line of letters they can see at 20 feet, but a person with normal vision can correctly identify these letters at a distance of 40 feet.
So the larger letters on the Snellen chart are designated with visual acuity fractions that have a larger second (bottom) number, which is the maximum viewing distance from which a person with normal vision can correctly identify the letters on that line of the chart.
The “big E” on the top line of the traditional Snellen chart is the 20/200 line. If this is the smallest line on the chart you can correctly identify from a testing distance of 20 feet, your distance vision is very blurred. How blurry? A person with normal vision could stand 200 feet from the chart and still be able to identify the letter. Roughly speaking, that person with normal vision has distance visual acuity that is 10 times clearer than yours.
Is it possible to have better-than-normal visual acuity? Yes!
The traditional Snellen eye chart has three lines of letters below the 20/20 line that contain letters that are smaller than those on the 20/20 line. The letters on the bottom line are half the size of “20/20” letters.
If you are fortunate enough to be able to identify the letters on this smallest (20/10) line, it means your distance visual acuity is twice as good as that of a person with “normal” vision. In other words, you can identify these very small letters from the standard testing distance of 20 feet, but a person with normal vision would have to be twice as close to the chart–only 10 feet away–to be able to correctly identify them.
How Visual Acuity Is Measured
Visual acuity usually is measured one eye at a time. The person having their vision tested covers one eye and reads aloud the letters on each row, beginning at the top. The smallest row of letters he or she can correctly identify indicates the distance visual acuity of that eye.
The traditional Snellen chart used in the United States has 11 rows of letters, with the following visual acuity designations for each row:
A common variation of this chart is the “tumbling E” chart, which contains multiple lines containing the block letter “E,” in progressively smaller sizes and displayed in varying spatial orientations (rotated in increments of 90 degrees). This chart often is used to test the visual acuity of children who are too young to fully know all the letters of the alphabet or to test the eyesight of illiterate adults.
Instead of saying the name of letters aloud, the child or adult being tested indicates with their extended fingers the direction of the “arms” of each “E” on the chart (up, down, right or left). Studies have shown visual acuity results obtained from a tumbling E chart correlate well with those obtained from a standard Snellen eye chart.
In Europe, Snellen visual acuity testing usually is recorded with metric notations, using a standard testing distance of 6 meters. In this system, a visual acuity measurement of 6/6 is equivalent to an American measurement of 20/20, 6/12 is equivalent to 20/40, and so on.
And in case you’re wondering if your eye doctor can correctly measure your distance visual acuity in an exam room smaller than 20 feet in length, don’t worry. With the help of mirrors and a projector, your eye care professional can simulate a standard testing distance of 20 feet in a room half that size–or even smaller!
By the way, to be granted an unrestricted driver’s license in most of the United States, your best-corrected visual acuity–that is, your distance visual acuity measurements obtained while you are wearing your eyeglasses or contact lenses (if you need vision correction)–must be 20/40 or better.
Good Vision Is More Than Visual Acuity
Distance visual acuity is only one aspect of good vision. Having 20/20 eyesight does not mean you have perfect vision.
Other important components of clear, comfortable vision include the ability to change focus and maintain focus on near objects, depth perception, peripheral vision, accurate eye movement and alignment, and more.
To see the world as clearly as possible and enjoy a lifetime of good vision, be sure to see your eye doctor for regularly scheduled comprehensive eye exams.
Don’t like wearing glasses? Maybe you just haven’t found the right frames. In addition to helping you see the world more clearly, eyeglasses should enhance (not detract from) your appearance, and should be comfortable, stylish and stay properly positioned on your face.
Here are a few essential tips when shopping for eyeglass frames:
Consider Your Face Shape
One of the most important factors to consider when selecting eyewear is to assess the shape of your face before trying on frames. Why? Because the most attractive eyeglass frames are those that complement and balance your facial features, not mimic them. In other words, if you have a very round face, rectangular frames or other frames with well-defined angles will look better than round frames (which will tend to exaggerate the roundness of your face).
There are seven basic face shapes. Though everyone’s face is a unique blend of shapes, here are some helpful tips to determine your predominant facial shape and which frame styles will look best on you:
- A round face has nearly symmetrical curves, and the height and width is nearly the same.
- Frames with angular shapes tend to look best on a round face, and rectangular frames that are wider than they are deep will help a round face look slightly taller, giving it a more pleasing oval appearance.
- An oval face is taller than its width and has gentle curves. An oval face generally is considered the ideal shape because of its balanced proportions.
- A person with an oval face can wear many frame styles successfully. To maintain the attractive balance of an oval face, look for frames that are as wide as (or wider than) the broadest part of the face and avoid frames that have an excessive width or depth.
- An oblong face is longer than it is wide and has a long straight cheek line and sometimes a longish nose.
- To make an oblong face appear shorter and more balanced, try frames that have more depth than width. Decorative or contrasting temples also can add width to the face for a more balanced appearance.
- A base-down triangular face has a narrow forehead and widens at the cheeks and lower portion of the face.
- To add width to the narrow upper third of the face, try frames that have a “cat-eye” shape and/or decorative detailing on the top half of the frame.
- A broad forehead and a slender jaw line characterize this face shape.
- To minimize the width of the top half of the face, try frames that are wider at the bottom, such as an aviator shape. Also, light frame colors and rimless frame designs tend to look good on this face shape.
- Diamond-shaped faces have a relatively narrow forehead and jaw line, and broad (sometimes high) cheekbones. This face shape is relatively rare.
- To highlight the eyes and soften the cheekbones of a diamond-shaped face, try frames that are prominent or distinctive at the top of the frame (at the brow line). Oval rimless frames also look good.
- A square face has a broad forehead and a prominent, angular jaw line, and the length and width of the face are of similar proportion.
- To make a square face look softer, try oval frames or other curved frame shapes that have more width than depth.
Choose a Frame That Complements Your Skin Tone and Eye Color
According to eyewear experts at The Vision Council, the best frame colors complement your natural skin tone and enhance the color of your eyes.
When considering your skin tone, understand that all complexions are categorized as having either a “cool” or “warm” color base. A cool complexion has blue or pink undertones; a warm complexion has a “peaches and cream” or yellow undertones.
There’s one exception: olive-colored skin is considered cool despite being a mixture of blue and yellow tones. Hair color also is categorized as cool or warm. Cool hair colors include blue-black, salt-and-pepper, auburn, strawberry blond, platinum blond, and silver-white. Examples of warm hair colors include yellow-blond, golden brown, black with brown undertones, and brown-gray.
Eye color is another secondary element in determining your coloring, but there are many subtle variations of eye color. For example, blue eyes can range from nearly violet (cool) to a pale blue-gray (warm). Brown eyes can vary from a light cider shade (warm) to nearly black (cool).
Once you consider your skin tone, hair color and eye color, it’s time to start picking frames that complement your coloring:
- Frame colors that usually look best on cool complexions include black, gray, silver, blue, blue-gray, pink, and dark tortoise.
- Frame colors that complement warm complexions include: gold, copper, brown, khaki, peach, fire-engine red, and blond tortoise.
You may be tempted to choose a frame color that “goes with everything.” But consider instead a color that truly flatters you and helps you make your personal style statement.
Make Sure It Fits
For both comfort and appearance, the size of your eyeglass frames should be in scale with your face size. Here are a few tips to make sure your eyeglasses will be comfortable and fit well:
- For adequate width, the edge of the frames should protrude slightly beyond the width of your face so that the frame temples don’t press against the side of your head.
- Make sure the temples are long enough so they can be adjusted properly behind your ears to keep the frame securely on your face when bending over or making quick movements. (Your optician will help with this fit.)
- The bridge of the frame should rest comfortably and securely on the bridge of your nose, without pinching. (Frames with adjustable nosepieces enable a more customized fit.)
Remember: even if you love the “look” of a frame, if it doesn’t fit properly, you’ll be unhappy in the long run.
Progressive lens “Zones”
Progressive lenses, sometimes referred to as “no-line” bifocals, provide vision correction for the three basic vision zones – distance vision, intermediate vision, and near vision. Because they provide vision in these three zones, they are often thought of as a type of trifocal.
In reality, progressive lenses are neither a type of bifocal or trifocal – they are “aspheric” in design, which means the curvature (and focusing power) gradually changes from the top of the lens to the bottom. It is this gradual change or “progression” in power from top to bottom that gives rise to the name “progressive.”
Progressive lenses provide a great solution for many people who find their present lens design limits their vision for a particular distance or activity. Progressives offer a range of vision as close to natural as can be obtained from prescription eyeglasses. They provide clearer vision not just for distance, intermediate and near but also for all distances in between. Because there is no abrupt change of power in the lens, there are no visible dividing lines.
The distance zone of the lens allows you to see objects from a few feet away to as far as your eye can see. The mid-range portion of the lens (“progression corridor”) allows you to clearly see anything at an arm’s length, such as your computer screen, objects on your desk, or items on a shelf at the supermarket. The lowest part of the lens, the near zone, allows you to see up close. The design of progressive lenses also allows a more natural and relaxed head posture when viewing objects at slightly longer reading distances, such as a newspaper or computer screen.
More Options – A variety of progressive lens designs are available today. Some progressives are designed with a wider intermediate zone to work especially well for computer use. Others have a larger reading zone. In the past, a larger frame was often required when selecting progressive lenses. If a frame was too small, a large portion of the near zone was removed when cutting the lens to fit the frame. Many lens manufacturers now offer “compact” progressive designs that work very well with smaller frames. Progressives are available in glass, plastic, polycarbonate, and photochromic (light-sensitive) lenses.
Modern progressive lenses offer outstanding clarity and comfort for seeing at all distances. Modern designs also make the adaptation process much easier than in the past. if you’ve tried progressives before, realize that much has changed in both lens design and materials. The next time you update your glasses, be sure to ask if progressive lenses might be right for you.
The benefits of modern-day computing and the Internet have led to a group of eye and vision-related problems. Collectively, this group is called Computer Vision Syndrome or CVS. CVS is caused by spending an extended amount of time looking at computer screens and other digital devices.
Between work and home computers, laptops, tablets and smartphones, it’s easy to log a lot of hours staring at a screen. (We’ve certainly experienced it ourselves!)
Looking at a computer screen is different from reading printed pages, and often makes your eyes work harder. For example, screen glare and reflections, low contrast, and poor definition make text difficult to read on a digital display. The way we interact with digital displays, software and Internet pages is also different from “traditional” paper-based reading and writing. And uncorrected vision problems and age-related vision changes can also be contributing factors for CVS.
Symptoms of CVS
Common symptoms that can begin or become worse due to CVS include:
- Blurred vision
- Dry and irritated eyes
- Neck and shoulder pain
When patients describe these symptoms, we use a comprehensive exam to check for visual clarity, focus, alignment, and movement issues.
Treatment and Preventive Measures for CVS
Reducing the stresses that build up with prolonged computer and digital device use is key to treating CVS. A combination of treatment and preventative measures can help protect and improve your eyesight. For example:
Find your sweet spot. Our eyes naturally look out and downward. To accommodate this, position your computer monitor so the center of your screen is a few inches below eye level, and 20 to 28 inches from your eyes.
Adjust your lighting. Give yourself ample lighting, but position your digital screen and your light sources to avoid glare.
Use anti-glare screens. When you have little or no control over your surrounding light, use an anti-glare filter over your computer screen. If glare is a problem at work, ask your employer to supply an anti-glare filter for your computer.
Take breaks and blink frequently. Allow your eyes to refocus at a distance and relax by looking around the room every 20 minutes. To prevent eyestrain, rest your eyes for 15 minutes every two hours. And be sure to blink! It helps keep your eyes moist and reduces your chances for developing dry eyes.
Your eyes work hard for you. Give them the rest and support they need to stay healthy. And if you’re concerned about CVS for yourself or a loved one, please call us to schedule an appointment. We’re here to help!

The eyes are highly metabolically active. In fact, the retina has the highest metabolic rate of any tissue in the body and is therefore vulnerable to oxidative injury. The most notable antioxidants which help to support the eye are vitamin C, vitamin E; the carotenoids lutein and zeaxanthin; selenium and phytonutrients. One method of assessing the antioxidant capacity of a particular food is expressed in ORAC units (Oxygen Radical Absorbance Capacity). Spices such as cloves, cinnamon and turmeric have a very high ORAC value. Natural cocoa, coffee and green tea are all great sources of antioxidants and have high ORAC values. Other foods high in antioxidants include berries, nuts, dried fruit, vegetables and beans.
Culinary preparation influences the quantity of antioxidants present in a particular food. Since many antioxidants are found in the peel or outer parts of fruit and vegetables, peeling eliminates a significant portion of antioxidants. When berries are boiled to make jam, the heat denatures the antioxidant capacity of the vitamin C and phytonutrients. Jam has little antioxidant capacity especially when compared to fresh berries. Steaming vegetables retain more antioxidants than boiling in water. The nutrient lutein found in kale is more accessible to our bodies when the plant cell walls are broken down through cooking or pureeing.
Oxidation is a natural process that occurs during normal cellular function as oxygen is needed to produce energy by the cells in our eyes and bodies. Free radical formation is derived from this normal metabolic process and from external sources like x-rays, cigarette smoking, air pollutants and sunlight.
Free radicals have a strong affinity for electrons and can damage cells and genetic material. To help with the battle against free radicals, every cell in the body creates its own antioxidant enzymes to diffuse free radicals. In addition, we can acquire antioxidants from food. A balance between free radicals and antioxidants is necessary for proper physiological function and to reduce oxidative stress.
Oxidative stress is thought to play a role in age-related macular degeneration, age-related cataract formation, glaucoma and other diseases. Including antioxidant rich foods in your diet everyday will help to reduce the risk or slow the progression of many chronic eye diseases associated with aging.

Acute inflammation is a normal and healthy part of the body’s immune response; it is needed for healing an injury or fighting an infection. However, chronic inflammation inside our body diminishes our body’s ability to repair itself. Researchers believe inflammation is linked to many chronic diseases such as rheumatoid arthritis, cardiovascular disease, Alzheimer’s and certain cancers. Eye conditions associated with inflammation include age–related macular degeneration, dry eye and uveitis.
An anti–inflammatory diet helps to promote the lowering of overall levels of inflammation in the body. Certain foods can ramp up the body’s inflammatory response while other foods dampen the response. Two essential fatty acids important to the balance of inflammatory response are omega-3 and omega–6. Omega–3’s form the building blocks of a number of anti–inflammatory compounds and lower the production of inflammatory proteins. Foods high in omega–3 fatty acids include oily, cold water fish like mackerel, salmon and black cod. The pro–inflammatory omega–6 fatty acids are found abundantly in corn, safflower and peanut oils, as well as processed and refined foods. The current recommendation is a ratio of one omega–3 fatty acid to four omega–6 fatty acids.
Culinary herbs and spices contain a vast array of powerful phytochemical compounds many which have anti–inflammatory properties. Turmeric is a highly pigmented root noted for both its anti–inflammatory and anti–oxidant attributes. Turmeric most notably is found in tandoori and curry powders. Ginger root is a common ingredient in Asian cuisine having both anti–inflammatory and anti–nausea properties. Oregano, basil and rosemary are delicious anti–inflammatory herbs. The phytonutrients allicin and quercetin found in garlic and onions have immunity boosting properties. Antioxidants protect the body from the inflammatory effects of free radicals. Colorful food like berries and peppers, as well as kale, beets and green tea are all excellent sources of antioxidants. Food high in fiber helps to minimize the inflammatory response that can occur following a rapid increase or decrease in blood sugar levels. Foods high in fiber include raspberries, beans, legumes, vegetables and cinnamon.
While dietary changes are not intended to supplant traditional medical therapies recommended by your doctor, food offers a delicious symphony of nutrients with anti–inflammatory disease–preventive benefits. The researchers at Oregon Health & Science University state that tart cherries have the “highest anti–inflammatory content of any food.” Making smart food choices to keep the immune system in balance will help facilitate health and well being. According to Emperor Charlemagne in the 9th century, “An herb is the friend of physicians and praise of cooks.”

At one time or another, nearly everyone struggles to balance the demands of work and family. Work isn’t necessarily associated with a career – it can be volunteer work, or tasks associated with a hobby or passion. And family can be a spouse, siblings, a much–loved pet or an aging parent.
So, it goes without saying that nearly everyone – including stay–at–home moms and professionals with no children – experiences the frustration and ensuing stress of being tugged at from different directions and feeling like there’s just not enough time in the day.
What’s even more complicated is that these feelings of anxiety, frustration or hopelessness often multiply, says life coach and intuitive teacher Amy Piper.
“Stress is not only created by a response to an external situation or event – a lot of daily stress is created by ongoing attitudes or recurring feelings of agitation, worry, anxiety, anger, judgments, resentment, insecurities and self–doubt,” Piper says. “These emotions are known to drain our emotional energy while we are engaging in everyday life. This leads to more fatigue and an endless cycle of negative emotions.
Piper says that finding balance starts with defining your identity and recognizing your personal mission in life. It means knowing who you are and what matters most, so that you honor your priorities in the way you want and need to honor them rather than adhering to society’s or someone else’s expectations.
“When your mind and emotions are balanced – when you are in heart coherence – your physical systems function more efficiently, resulting in emotional stability, mental clarity and improved cognitive function,” she says.
Here are a few tips Piper says can help balance out your world:
- Clearly define who you are and what’s important, and prioritize accordingly. Start the day with a list of priorities that are intimately related to the larger goals of your work, and then give yourself a 6 p.m. deadline to complete them. In the meantime, commit to the larger values in your life – relationships, exercise, spirituality and fun – in a concrete way by putting those activities on your calendar.
- Establish routines and habits that support the goals you deem important. Habits (good and bad) become the cornerstones of your lifestyle over time. For example, if long–term health and vitality are important to you, incorporate walking into your daily routine, and plan family time that’s activity–centered. The steps add up over the weeks and years, and can make a huge difference. And don’t forget your vision. Remember to protect your eyes from the sun, take breaks from your electronic devices and schedule regular eye exams.
- Eliminate or reduce time suckers (activities or people) that don’t add value to your life and support your long–term goals or mission. You need to know how to recognize and hold honest boundaries in relationships, remaining true to your own needs while being connected to other people.
- Delegate tasks that are not important to your goals. This means you must recognize that some things just don’t matter – being an awesome cupcake baker is not essential to being a loving mother. Hire someone else to bake your cupcakes or turn the baking experience into a project you can enjoy with your child.
- Be present and experience the fullness of the moment. If you’re off the clock, unplug from work, set your phone aside and immerse yourself in the present situation and company without burdening yourself with guilt, frustration or anxiety. Engage in authentic conversations with your family members and enjoy their company without being distracted or otherwise preoccupied.
Learn to recognize when imbalance is creating stress and be deliberate about honoring your priorities. You’ll be happier and healthier – mentally, spiritually and physically.
Working for long periods on a computer is a demanding visual task. Daily, millions of Americans use a computer for hours at a time, both at work and at play. Many of them routinely experience symptoms of headache, fatigue, blurry vision, scratchy eyes, or pain in the shoulders, neck or back.
Our eyes and brain react differently to characters displayed on a computer screen than they do to characters printed on paper. Computer images are less distinct than printed characters, may have perceptible flicker, and usually have less contrast between characters and the background. Computer users must rapidly switch focus from keyboard to monitor and vice versa; this constant refocusing can also contribute to symptoms.
What are computer glasses?
Computer glasses are prescription glasses that are specifically designed to wear when doing computer work. They allow you to focus your eyes comfortably on a computer screen, which is usually farther away than reading material is held.
General purpose bifocals and trifocals are not designed for computer work. Bifocals force the wearer to tilt the head back in order to focus on the screen, while looking through the lower portion of the bifocal lenses. While conventional trifocals allow a more normal head posture, they generally have too small an area for viewing the computer screen and the visible dividing lines can be a significant distraction.
Which kind of computer glasses are the best?
There is no one type of computer glasses that fits all or is the best for everyone. Visual ability, personal preferences of the computer operator, the type of work, the distance between the computer user’s eyes and the monitor, and lighting design in the workplace should all be taken into consideration when selecting computer glasses.
Lens design and lens options vary significantly from manufacturer to manufacturer. It’s always best to make your final selection of computer glasses based upon the advice and recommendations of your eye doctor; however, all of the options listed below have proven to be beneficial for computer users.
Progressive Addition Lenses
Surveys conducted among persons working long hours with computers revealed that Progressive Addition Lenses (PALs) were the lenses of choice. These modern lenses have more than just the cosmetic advantage of “no lines.” They provide all the benefits of bifocals but add the feature of continuous clear vision at all distances, including mid-range distance (arm’s length). Several lens manufactures have introduced PALs designed specifically for computer use. These specialized PALs allow an even wider field of view for near and intermediate working distances than standard PALs.
Today’s advanced Anti-Reflective (AR) coatings eliminate bothersome reflections from overhead lights and computer monitors. AR coatings not only reduce reflections but increase the amount of light transmitted through the lenses to the wearer’s eyes. It may seem strange but AR coated lenses actually appear clearer than uncoated clear lenses…sometimes appearing to be nearly “invisible.”
Natural light sources (windows) can be especially bothersome in the workplace. When a window is located over the wearer’s shoulder, natural light striking the back surfaces of the lenses bounces directly into the wearer’s eyes. Since outside light levels are quite high, the intensity of these reflections can be even greater than reflections from light sources within the workplace. An AR coating placed on the back surfaces of the lenses eliminates these “outside” reflections as well.
High Index Lenses
Modern technology has created lenses that bend light differently so that stronger corrections are thinner than when made in conventional materials. Such lenses are called “high index”. High index materials can drastically reduce the thickness and weight of prescription lenses. Lens thickness can sometimes be cut by as much as 50% by simply using a higher index material and choosing an appropriate frame. High index materials are more shatter resistant than traditional plastic and will improve the appearance of any prescription.
Note: High index lenses bend light to a greater degree so an anti-reflective coating is especially recommended to maximize their performance and cosmetic advantages.
- Computer glasses provide a wide field of view so that the user can clearly read both their computer screen and closer printed material.
- Anti-glare coatings can be used to eliminate bothersome reflections from windows, overhead lights and other nearby computer monitors.
- Use of high-index lens materials keeps lenses thinner and lighter in weight.
- Computer glasses give the most natural, comfortable vision possible.
- Computer PALs provide clearer vision for reading and viewing screens at intermediate distances better than any previously designed lens.
If you’re one of the millions of people who use a computer on a regular basis, be sure to ask your eye doctor about “computer glasses” the next time you have your eyes examined or replace your current prescription.
