Computer vision syndrome is a variety of eyestrain unique to computer users. Human eyes don’t react the same way to characters on a computer screen as to printed characters. Although the symptoms of computer vision syndrome resemble common reading eyestrain, computer vision problems may require different solutions. For example, vision tests and prescriptions for corrective lenses may need to take into account the special requirements of computer vision versus standard reading. Other improvements may be realized by providing technology furniture to make the computer reading experience more visually ergonomic.
The Level of Interior Light
Excessively bright indoor light causes eyestrain when viewing computer screens. When using computers in an office or classroom, the level of interior light should be half that of a standard environment. Shades or blinds can be utilized to take the glare of outdoor light off computer screens. Installing anti-glare screens on computer monitors can also reduce glare from indoor sources. Nova Solution’s Downview workstation incorporates a flat-screen display below the surface of the desktop, shielded from sources of reflection and glare and covered by a plate of anti-glare glass.
Constant refocusing caused by shifting back and forth between material on the desktop and an eye-level monitor also aggravates eyestrain. Because the Downview monitor is incorporated into the desktop, the workstation requires minimal shifting of focus from printed material on the desktop to the computer display, reducing eyestrain.
General workstation ergonomics, particularly those that support the head and neck muscles, also have visual benefits by reducing stress on the eyes. A standard flat-screen display mounted at eye level is not the optimal position for reading and does not promote stress-free computer viewing. In the Downview workstation, the monitor beneath the desktop is angled at an ergonomic 30 degrees, approximately the same position as a book held in your hands for reading. This more natural viewing attitude reduces strain on head and neck muscles that contributes to visual fatigue.
