When you work at a computer for any length of time, it's common to experience eye strain, blurred vision, red eyes and other symptoms of computer vision syndrome (CVS). This is because the visual demands of computer work are unlike those associated with most other activities.
How dose the computer screen effect your eyes?
If your eyes feel irritated and dry after a long workday in front of the computer, it is caused primarily from staring at the glow that emanates from a screen and something called blue light.
What we see – the visible spectrum of light – consists of a range of colors, from blue-violet on the lower end to red on the higher end. Light on the lowest end of the visible spectrum has the shortest wavelengths; light on the highest end has the longest wavelengths. Since shorter wavelengths emit more energy, blue light is also known as High Energy Visible (HEV) light.
Our eyes were not evolved for our modern digital world. The eye's cornea and lens aren't good at filtering HEV light from reaching our retina, the thin layer of light-receiving tissue that lines the back of the eye. Over time, this can cause damage to its light-sensitive cells. As we age, it gets worse and can make us more susceptible to eye diseases such as macular degeneration and cataracts. Young children are even more sensitive to blue light exposure since the lens of their eyes are even more transparent than adults, allowing more HEV light to pass through.

Lens designs for computer eyewear
Many special purpose lens designs work well for computer glasses. Because these lenses are prescribed specifically for computer use, they are not suitable for driving or general purpose wear.
The simplest computer glasses have single vision lenses with a modified lens power prescribed to give the most comfortable vision at the user's computer screen. This lens power relaxes the amount of accommodation required to keep objects in focus at the distance of the computer screen and provides the largest field of view.
Single vision computer glasses reduce the risk of eye strain, blurred vision and unnatural posture that can cause neck and back pain, and can be used comfortably by young and old computer users alike.
Another popular lens design for computer glasses is the occupational progressive lens — a no-line multifocal that corrects near, intermediate, and, up to a point, distance vision.
Occupational progressive lenses have a larger intermediate zone than regular progressive lenses for more comfortable vision at the computer. But this leaves less lens area for distance vision, so these lenses are not recommended for driving or other significant distance vision tasks.
Other lenses used for computer glasses include occupational bifocal and trifocal lenses. These lined multifocal lenses have larger zones for intermediate and near vision than regular bifocals and trifocals, and the position of the intermediate and near zones can be customized for your particular computer vision needs.
