Physical tips - eye strain

                    Most computer users suffer from the problem of tired eyes, dark circles and headaches. Follow these tips to avoid them:                    Studies have shown that stress, active nightlife and above all, the fact that most of us spend maximum time in front of the computer lead to dark circles, puffed and tired eyes. Timely treatment is essential for such difficulties.
                     Specifically with computer users, physical and visual discomfort is experienced by many after just a few hours in front of computers. It appears that PC users suffer from repetitive stress of their eyes and want an immediate solution to revive the tired eyes.
                     Studies show that most computer users start to feel eye-muscle stress after two or more hours at the computer. This usually starts with tired eyes. With more time at the computer, discomfort frequently spreads to the head resulting in headaches, burning of the eyes, blurred vision, loss of focus, double vision, and neck and shoulder pains. Before it is too late, your stressed out eyes need to be relaxed and revitalized so that you feel fresh later in the day.

Tips to reduce eyestrain :-

Modify your workstation. Adjust your workstation and chair to the correct height.
Use proper lighting.
Match the computer screen to the brightness of the environment. The contrast between the background and on-screen characters should be high.
Minimize the glare. Use window shades, blinds or drapes to block excessive sunlight or install an anti-glare screen to minimize reflections.
Take frequent breaks. Full-time computer users should take a 10 minute break every hour.
Blink more often. Tears in the eye evaporate more rapidly during long non-blinking phases and cause dry eyes.
Get an eye examination done.
Re-focus your eyes. Look away from your computer screen every 10-15 minutes and focus for 5-10 seconds on a distant object.
Exercise even when sitting. Move about or exercise frequently.
Get sufficient sleep. Fatigue promotes eyestrain.

The most common hazards to the eyes and face are:

dust and dirt blown around by the wind;
tree branches;
flying particles from drilling, cutting, digging and other similar operations;
ultraviolet radiation from welding and electrical work;
splashes;
fibres from insulating materials, such as fibreglass; and
irritants and corrosives.

A few suggestions

For cuts near the eye - To avoid causing further damage, do not rub your eye, exert pressure or wash the cut. Bandage it loosely and obtain medical assistance immediately.

For bumps or blows to the eye - Apply cold compresses to your eye for 15 minutes and seek medical assistance.

For foreign bodies in the eye - If dust particles enter your eyes, wash your eyes immediately with special products or clean water. Flush your eyes until the dust is gone. If you cannot wash it out, cover your eyes loosely and obtain medical assistance.

Note : Never rub your eye; you could scratch it or embed the particle in your cornea.

For particles embedded in the eye - Never try to remove embedded particles yourself; you could cause further damage. Apply a loose bandage over both eyes to avoid blinking and have someone drive you to a doctor.

For chemical splashes in the eye - Seconds count! Go immediately to the nearest clean water source. Hold your eye open and flush it with water for at least 15 minutes. Then seek medical treatment.

For injuries from light sources - If your eyes are exposed to welding rays, laser beams or other intense radiation, you may not feel any pain right away. Some four to twelve hours later, your eyes may be sensitive to light, feel gritty and be red and swollen. Keep them closed and apply cold compresses. Obtain medical treatment.

Note: Passers-by may be injured by welding rays if their eyes are not protected.
