Blindness is a feared condition among human beings. Blindness can change much of our world and rob us of our freedom. These fears should remind us to protect our eyesight now for better eyesight in the years to come.

One of the keys to better eyesight is a regular eye exam. After a person reaches age forty, he should be tested for glaucoma. The test should then be preformed every five years. Glaucoma is the second leading cause of blindness around the world.

In countries that are just developing, the water supply is not pure and parasites can cause blindness. In addition, treatment is not available for cataracts which can also lead to blindness. Providing pure water can prevent parasitically cause blindness and surgery can cure blindness caused by blindness, however these treatments must be made available.

One of the leading causes of blindness in the U. S. Is macular degeneration. Macular degeneration is hereditary and becomes apparent as its victim ages. It can cause a loss of sight in the central field of the retina, allowing the person to see only around the edges of the field of vision. Currently, there is a study testing nutritional supplements effect at improving the lives of macular degeneration.

There are also diseases that may cause the cornea to become clouded causing blindness. The treatment for this condition is a corneal transplant.

Diabetic retinopathy causes blindness in diabetics. Blood vessels form around the retina and break. In mild cases, this leads to blurring of the vision. As the problem develops, it can cause the patient to only be able to distinguish between light and dark.

Blindness may also be caused by an accident. Therefore, it is imperative that you do everything possible to protect your eyes from foreign objects being thrown by power equipment as well as harmful chemicals. The best protection is the use of safety glasses.
