Who Is Affected by Computer Vision Syndrome?

More than 143 million Americans work on a computer each day, with 88% of them suffering from Computer Vision Syndrome (CVS). In addition, nearly 54 million children work at a computer each day either at home or in school. Prolonged computer use can place excess stress on the focusing system of the eye and impact performance and comfort.

What Are the Symptoms of CVS?

If you or your child spend more than two hours each day in front of a computer monitor, you likely are experiencing some degree of CVS. CVS symptoms include:

• Headaches
• Loss of focus
• Burning/tired eyes
• Double/blurred vision
• Neck and shoulder pains

Will Crystal Eyes RX ^TM Make the Monitor Clearer?

Yes, because they will eliminate the constant refocusing effort that your eyes go through when viewing the monitor. It has also been proven clinically that having the correct prescription designed specially for computer use increases productivity and accuracy.

Will Glare Screens Prevent CVS?

Glare screen filters may help somewhat, but they only solve the problem of monitor glare-not the visual problems related to the constant refocusing of your eyes when working at a computer. Crystal Eyes RX ^TM use the custom tailored prescription for the computer user's monitor distance, which alleviates the fatiguing effects of CVS-Guaranteed.

What About the Tints for Computer Lenses?

If you work in a brightly lit office, you will benefit from the Crystal Blue tint applied to your computer lenses. This can cut the amount of light that reaches your eyes by 15% and provide relief from the stress of fluorescent lights.

If I Don't Have Symptoms of CVS, Can I Still Benefit From Crystal Eyes RX ^TM?

YES. According to a University of Alabama study (2002), computer users who are not experiencing symptoms of computer vision syndrome may also need computer eyewear. The study reports that it does not matter whether subjects reported symptoms of CVS. The fact is that viewing a computer screen is a different stimulus for the eyes than reading printed materials. It is much more difficult for the eyes to focus on pixels than on printed characters. Individuals with no visual problems may still be losing productivity and accuracy at the computer. This is the number one reason to get a regular eye exam from a computer vision specialist

Will Insurance Pay for These Glasses?

Most of the vision insurance plans cover an annual routine eye exam. However, not all of the insurance plans cover computer eye exams. In order to maintain the highest level of quality, we fabricate our own lenses and inspect each lens for quality and accuracy. If your insurance carrier is an authorized supplier of Crystal Eyes RX ^TM, the glasses should be covered under your plan.

Will My Reading Glasses Work at the Computer?

NO. As with anything else you do in life, it is important to have the right tool for the job. You would not wear dress shoes to run a marathon. The same goes for your vision: you would not use distance glasses for doing close work. Reading glasses are usually prescribed to read at a distance of 16"-18", but computer glasses are usually designed to work at 20" to 28" because this is the recommendation by doctors. So, your reading glasses are not going to do the job.

Isn't Ergonomics the Solution to Computer Eyestrain?

Ergonomics is important - changing one's computer workstation can certainly help to minimize other physical symptoms. But ergonomics cannot fix a visual problem. Clear, comfortable focus at the proper computer distance (20" to 28") is most important. This can be done only with the right computer lens prescription.

Is It True That Wearing Computer Eyeglasses Will Make My Eyes Worse?

This is not true. Crystal Eyes RX ^TM can prevent the strain caused by computer use. Depending on your age and prescription, an eyecare professional will probably fit you in either single vision or multifocal lenses.

What Can I Do About It?

The solution is simple: see an eyecare professional that treats CVS. In most cases, standard glasses or over-the-counter readers are not accurate enough, because they fail to address the area where the computer monitor rests (20-28"). Once your eye doctor has performed an examination, your Crystal Eyes RX ^TM can be fabricated to increase your comfort and productivity while using the computer.

Glossary

Accommodation
Eye's ability to automatically change focus from seeing at one distance to seeing at another.

Anti-reflective coating (AR coating)
Thin layer(s) applied to a lens to reduce the amount of reflected light and glare that reaches the eye

Aspheric
Aspheric lenses are popular among people who have strong prescriptions because they are thin and lightweight, and reduce distortion and eye magnification. Astigmatism Condition in which the cornea's curvature is asymmetrical (the eye is shaped like a football instead of a baseball); light rays are focused at two points on the retina rather than one, resulting in blurred vision.

Bifocal
Lens with one segment for near vision and one segment for far vision.

Bridge
The part of eyeglasses that extends across the nose.

Computer Ergonomics
Ergonomists study human capabilities in relationship to work demands. The arrangement of the computer user's work space is dictated by the length of their arms and legs.

Computer vision syndrome
Collection of problems, mostly eye- and vision-related, associated with computer use. Symptoms include eyestrain, dry eyes, blurred vision, red or pink eyes, burning, light sensitivity, headaches and pain in the shoulders, neck and back.

Cylinder
this is the measurement of the amount of astigmatism in the prescription.

Diopter
Unit which measures the refractive (light-bending) power of a lens; eyecare practitioners use it in eyeglass. A negative number refers to nearsightedness, while a positive number refers to farsightedness.

High-Index
Type of lens with a higher index of refraction, meaning that light travels faster through the lens to reach the eye than with traditional glass or plastic. It is denser, so the same amount of visual correction occurs with less material so the lens can be thinner.

Monovision
Vision correction method for those with presbyopia in which one eye is corrected for near vision and the other for far, either through contact lenses or refractive surgery. Monovision eliminates the need for reading glasses, but does have some drawbacks, including decreased depth perception.

Multifocal
Type of spectacle or contact lens design that includes more than one focal area, such as bifocals or trifocals.

Myopia
Also called nearsightedness. Condition in which the length of the eye is too long, causing light rays to focus in front of the retina rather than on it, resulting in blurred distance vision. Additional symptoms include eyestrain, poor night vision and squinting

Nearsightedness
Also called myopia. Condition in which visual images come to a focus in front of the retina, resulting in defective vision of distant objects

Presbyopia
Condition in which the aging eye beginning at around age 40 is unable to focus at all distances, often noticed when print begins to blur. Additional symptoms include eyestrain, headaches, and squinting

Progressive lenses (PALs)
Multifocal lenses whose corrective powers change progressively throughout the lens. Each area is blended invisibly into the next, without the lines that traditional bifocals or trifocals have.

Pupillary distance
This is the distance between the center of each pupil

Reading glasses
Glasses to help with close work, particularly for people who are presbyopic.

Scratch resistance coating
A coating applied to lenses to help prevent scratching. Although no lens is scratch proof it helps minimize scratching.

Tint
color applied to a lens to absorb part of the light spectrum. Can be applied in different colors and different amounts.

Ultraviolet (UV)
the invisible part of the light spectrum whose rays have wavelengths shorter than the violet end of the visible spectrum and longer than X-rays. UVA and UVB light are harmful to your eyes and skin.
