Computer Eye Glasses

Computer glasses refers to the use of special eye glasses to reduce eye strain from viewing computer monitors.

When you work at a computer for any length of time, it’s common to experience blurred vision and other symptoms of computer vision syndrome (CVS). You’re more likely to experience eyestrain and eye fatigue while sitting at the computer, because of unique visual demands that are unlike those associated with most other activities.

If you’re under age 40, blurred vision may be due to inability of your eyes to remain accurately focused on your computer screen for a sustained time period. Or eye fatigue and blurriness may be related to problems with quickly and accurately changing focus, such as when you shift your gaze from your monitor to your keyboard and back again. This lag of accommodation can be associated with CVS.

If you’re over age 40, the problem may be due to the onset of presbyopia — the normal age-related loss of near focusing ability. This, too, can cause CVS symptoms.

What can you do? For one thing, obtaining customized computer glasses can make a world of difference in your comfort level while you're using the computer. These special-purpose glasses are prescribed specifically to reduce eyestrain and to give you the most comfortable vision at your computer.

Design Considerations for Computer Glasses

A solution is to provide low powered rimless reading glasses with ultra light frames and permitting the selection of lenses to match each eyes requirements.
If you do wear reading glasses you will find that a lower power is needed for computer use and these are not readily available over the counter.

The Best Possible Solution, from the optical supply system, is of course computer glasses made to your exact prescription and workplace setup. Unfortunately the cost is often very, very high and it is difficult to ensure you obtain exactly the Rx and lens coatings and design (bifocal, progressive, which manufacturer)

Of course you must be prepared to work out the corrections required by following our advice in selecting a set of step diopter lenses to provide the proper computer glasses for your Rx and workplace distances.

• Anti-Reflective Coatings on Computer Glasses

While A/R coatings do require more frequent cleaning the coating also increases scratch resistance.

Glare, when referring to computer use really refers to light intensity higher than that of the monitor that acts as “visual noise” and affects the eye’s ability to focus clearly on the monitor.

• Tinted Lenses in Computer Glasses

Tinted Lens to cut down on excessive “blue light” spectrum.
However any tint will cut down on light transmission and cause pupil dilation resulting in a narrower depth of field.

• Reading Glasses as Computer Glasses

Reading Glasses are not suitable for most computer users as you cannot choose individual eye strengths and the interpupillary distance can be quite far off (one size fits all) thus inducing “prism” and causing additional eyestrain.

• Progressive Lenses for Computer Glasses

Progressive lenses are often prescribed for use in Computer Eye Glasses.

Aside from costing more than normal lenses these require very careful prescriptions and fitting of the eyeglasses for comfortable wear AFTER an adjustment period.

Without appropriate eyeglasses, computer users can often end up with blurred vision, eyestrain, and headaches (computer vision syndrome).
Worse still, many people try to compensate for their blurred vision by leaning forward, or by tipping their head to look through the bottom portion of their glasses. Both of these actions can result in a sore neck, sore shoulders and a sore back.

These lenses are only 26mm in height to permit viewing “underneath” to focus on keyboard etc.
