Causes of Cataract -
The lens is situated behind the iris and the pupil and it works like a camera lens. If focuses light on the retina so that an image can be formed on the retina. Like the camera lens, the eye lens can also adjust the focus and helps you to see things from all the angles. This lens is made up of water and protein and hence it is very clear and pure. But with growing age, this protein starts clumping together and this can cloud some area of the lens. This is what is known as cataract and if you will not get it treated then it will spoil the entire lens by clouding it more and more. Smoking and diabetes are also responsible for causing cataract. People can have cataract in their forties and fifties also. But by the age of 60 the clouding of the lens is more and thus many people get diagnosed with cataract in this age.
People who are diabetic are among the ones who can have cataract. Also those who smoke and drink too much alcohol can also have cataracts.
Preventing Cataract -
You should protect your eyes from harsh sunrays by wearing sunglasses and sun hats. Avoid smoking and stop drinking alcohol, as these are among the top causes of cataracts. Having vegetables, fruits, seeds, nuts can reduce the chances of getting age related cataract. You should undergo an eye check once every year in your young age. As you reach your thirty, forty, fifty, etc. make sure that the number of eye check ups per year increase in the same manner. If you have any other eye conditions then get fast treated for them. If you get any eye injury then show your eye doctor and ensure that it has not caused any internal damage to your eyes.
