Presbyopia, (the direct translation is "elder eye"), is the progressively diminished ability to focus on near objects with age. Or, as some people put it, their arms become "too short" to hold reading material at a comfortable distance. Loss of power of the ciliary muscles (the muscles that bend and straighten the eye lens) is considered a major cause of this.

Computers have, almost overnight, become the primary medium through which we give and receive information. The near focusing effort required for working on the computer puts strain on those same ciliary muscles, a strain the eye has never had to deal with before. In people aged around 30-40 a decrease in the accommodative focusing mechanisms of the eye can be a setting for early presbyopia.

Why does this happen? Our eyes have a hard time focusing on pixels vs. print. This is natural enough as pixels are a whole new visual ball game. Our eyes relax to something called the RPA (Resting Point of Accommodation). Right now, for everyone, the RPA is further away than the working distance to the computer. Again this is natural enough as most of us have only started working with computers in the last 15 years.

When we are working on the computer our eyes focus on the screen. But they cannot sustain that focus and relax regularly to a point somewhere behind the screen (the RPA). Then they strain again to refocus on the screen. This constant flexing of the ciliary muscles is what creates fatigue, generates burning and tired eyes, and all the other symptoms associated with eye strain from computers, aka CVS (Computer Vision Syndrome).

What is the solution? Computer Vision Syndrome can cause a multitude of symptoms, leading to loss of productivity. CVS can cause headaches, blurred vision, neck and shoulder pain, loss of focus, tired, burning eyes, and double vision. If you are over forty, some of these symptoms may be presbyopia. For those under forty, ey e strain from computers likely creates a situation of CVS and the need for computer screen glasses.

Only when your eyes can clearly focus at the plane of the computer screen can you experience relief from the fatiguing effects of Computer Vision Syndrome and computer monitor eye strain. Digital performance eyewear increases visual performance when interacting with any digital screen and mitigates the effects of CVS.

Computer glasses give users a distinct advantage in visual efficiency, visual endurance and visual recovery. High-performance digital eyewear both protects you from the negative visual impact of viewing digital data, and at the same time, enables anyone on a digital screen to be more productive. The Macular Degeneration Support organization says that because your eyes react differently to the stimulus of a computer 70-75% of computer users need computer eyeglasses.
