The eyes are one of the most precious gifts of God to mankind. It is best to take proper care of the eyes because modern lifestyle puts the eyes through a lot of stress and strain. It is important to protect the eyes from damage as far as possible.
If you want a healthy eyesight, you should avoid looking at very bright objects like the sun or a flash light. Compute screens and TV screens should be lowered down if possible. Use a glare guard when using computers.
Avoid reading and studying in places where there is poor lighting. Always try to do all reading in a place where there is plenty of light. This is going to protect your eyes from undue strain and exertion. Choose a soft light that is not productive of a glare and uses a reflective lamp for interaction with your eyes.
While using the computer or watching the television, use the 20-20-20 rule: look at something kept at least 20 feet away from you after you spend 20 minutes before the television or the computer.
Do this every 20 minutes. This is going to reduce the strain on your eyes. Blinking the eyes occasionally helps too because it puts in an amount of lubricant in your eyes.
Quit smoking and drinking at once if you are looking for a good eyesight. Both smoking and drinking have been found to be detrimental to a good eyesight.
There have been cases of optic nerve damage and even blindness due to the incidence of smoking.
