Eye strain is a common problem nowadays (especially for those who work in front of computer all the time). This include a number of symptoms, including dry eyes, irritation, sensitivity to light, trouble focusing, and blurry vision. If not addressed, these symptoms can turn into something chronic. If you strain your eyes and have trouble seeing or focusing, it could end up impacting your productivity and effectiveness too.
TAKE A BREAK
The best way to prevent eye strain is not to use them as much. That might be difficult to do. Luckily, your eyes use more than one set of muscles. That means you can relax one muscle while using another. Shift your focus from near to far on a regular basis. Shift focus from up close to at least 20 ft away. If you are at your computer look out the window for a minute. If you are driving check your speedometer every so often.
Use indirect or reflective lighting whenever possible to reduce glare. Try switching your monitor or TV to flat screen technology. They are not as reflective. Use anti-glare technology. Use an anti-glare filter on monitors. Use anti-glare glasses when driving (especially at night) or working in general.
Ensure there is a good contrast with what you are looking at but reduce contrast. Too much contrast with the surrounding area will cause strain through your peripheral vision. Keep overall lighting levels at a moderate level, so there is good contrast around you, but glare does not become a problem. Use task lighting to aid eyesight at specific tasks. Adjust the contrast setting on monitors and screens to the best effect. Use glasses or sunglasses with polarized lenses as they increase contrast and cut down on glare.
Use full spectrum lighting. Lighting, like sunlight, that covers the visual spectrum makes things easier to see. Adjust the colour setting on monitors and screens. Some even allow you to adjust the colour temperature. Use a combination of fluorescent and incandescent lighting. Use full spectrum fluorescent bulbs.
STRENGTHEN YOUR EYES
Eye strain is the strain of the muscles controlling the eyes. Strengthening these muscles with a series of eye exercises will go a long way to preventing eye strain. You can go to You Tube and watch some videos on exercises for the eyes!
