Studies suggest the average office worker stares at a computer screen, anywhere between 6 and 8 hours per day. This type of behavior can drastically affect vision in the long term, and can cause:
- blurred vision
- neck pain
- eye strain
- dry eyes
- irritated eyes
- double vision
- difficulty re-focusing
Fortunately, the detrimental effects of what is known as “Computer Vision Syndrome” can be fought by employing five simple ways:
Wear “computer Glasses”
Computer spectacles are fitted with special anti-reflective prescription lenses designed to reduce the harmful effect of glare from digital screens and light sources. Beware: computer glasses are designed for use in environments poorly lit, and not ergonomically optimized. Use of these devices in an environment with adequate lighting and where digital screens have been optimally calibrated, can turn into a hindrance.
Optimize your monitor settings
When staring at a screen for long periods, the eye goes through a self-adjustment, to compensate for poor, or excessive lighting. This causes the eye to strain. It’s important to adjust contrast, color, brightness and frequency of the monitor. bigger, ideally 21-inches and up, LCD monitors with a higher frequency are best, as they offer less flicker and a larger display area that can be seen from a distance. It’s important to keep the eyes at at least 20 inches from the monitor. the screen should also be positioned slightly inclined, so as to look at it slightly downward.
In most office environments, overhead lights can be excessively bright, producing harmful glare. the same can be said for desk lamps, as well as any other light source that hits the eye directly, including window light. The goal is to avoid bright light being projected directly on the surface of your eye for extended periods of time. Overhead lights should be diffused, softer, so as to create a clear, yet soft ambiance. Desk lamps should be pointed downwards, with the shade allowing light to bounce off the surface of the desk, instead of the eye. Using blinds and a glare screen can also improve lighting substantially.
The 20-20-20 rule
A clever trick to remind yourself to take a break, every 20 minutes, to stare for at least 20 seconds, at an object that is at about 20 feet away.
Blinking is the natural way to wash your eyes. It produces tears that coat the surface of the eye and disinfect it from bacteria.
Following these five simple rules, will make a difference in your productivity and comfort. Come and see our professional optometrists at Iris Optometric Center, for more information on preventative eye care and what you can do to protect your vision.
