Sight is one of the five senses that enable us to identify what we encounter in our environment. It can give us pleasure when we observe a beautiful sunset or a work of art, and it can protect us from traumatic injury, such as stepping in front of a car or other conveyance, falling down a step, or inadvertently stepping into a lake or pond and possibly drowning. Several diseases can impair our sight and precautions should be taken to avoid situations which could trigger these diseases.

 

In India people should take the following steps to maintain their sight.

 

Anywhere a person is outdoors, they should avoid looking directly at the sun, since the sun’s rays can cause cataracts. The cornea is the transparent layer that covers the front of the eyeball. Cataracts can cause the cornea to become cloudy, and if this happens, then sight is impaired. When out in the sun one should always wear polarized sun glasses that block the ultraviolate (UV) rays of the sun that speed up the formation of cataracts that cloud your cornea and reduce your vision.

 

The people of India should also avoid sources of dirty water that they might get into their eyes. Water infected with microorganisms can transmit microorganisms such as amoeba to a person’s eyes and destroy that person’s sight. Therefore, the water used for face washing in India should be boiled before use, or distilled water should be used. People should be educated as to the importance of these practices. It is not difficult for an adult to realize the importance of staying out of the sun to slow down the development of cataracts and avoiding polluted water.

 

Thus, there are many steps the people of India can take to preserve their eyesight and enable them to have the best vision possible well into their old age.
