Computer Vision Syndrome
If you use a computer regularly, you probably suffer from Computer Vision Syndrome (CVS). CVS simply refers to a collection of eye and vision problems associated with computer use and about 75% of computer users have it.
Computer Vision Syndrome Overview
Symptoms of Computer Vision Syndrome
Typical symptoms of CVS include:
- Eyestrain or eye fatigue
- Dry eyes, burning eyes
- Light sensitivity
- Blurred vision
- Pain in the shoulders, neck or back
Causes of Computer Vision Syndrome
Possible causes if CVS include:
- Most people wear glasses that do not fully correct the intermediate zone where the computer monitor is usually placed.
- Many people tend to lean forward or tilt their head to look through the bottom portion of their glasses, which can result in a sore neck and shoulders. Poor office and room lighting can be major sources of glare and reflection, which can also lead to eyestrain.
- People in their 40’s and older suffer blurred vision at the computer because of presbyopia; the loss of flexibility of the lens of the eye which makes it difficult for them to focus on close objects.
- In middle age the eye loses its ability to switch focus rapidly from distance to intermediate to near.
Treatment of Computer Vision Syndrome
Computer glasses usually make a major improvement in your comfort level while you’re using the computer.
- They correct your blurred vision and relieve symptoms caused by your struggling to focus, such as eyestrain and burning.
- Anti-reflective lenses can significantly reduce the amount of glare and reflected light that reach your eyes.
Computer Lens Designs
Our most popular computer eyeglass lens is the computer progressive, a no-line lens that addresses near and intermediate vision but still allows for some distance vision. It has a much larger intermediate zone than regular progressive lenses. This lens allows you to see well in the office environment but is not designed for regular wear as the distance area is reduced to allow for the increased intermediate zone.
