Nowadays, blindness is a big concern that bothers a large number of people worldwide. But as for the causes for blindness and how to prevent blindness, most people do not have a clear idea. The following will give a brief introduction on this. Researches show diabetic related eye complication, glaucoma and degeneration of the central retina tissue are leading causes of blindness in the USA.

Among all the causes for blindness, cataracts are No. 1, which affect 20 million people. But thanks to the rapid development of eye technology that most cataracts can be treated with surgery and artificial lens implants. But why it can also cause so many people blind? This mainly has the following two reasons: First, for some people, due to some other diseases, such as uncontrolled diabetes or bleeding disorders, they can not take the surgery. Besides, the surgery cost is also another reason for not able to take the surgery in time and then miss the time for treatment.

The second leading cause for blindness is diabetes complication, which leads more than 4 million people to blindness. The reason is that people with serious diabetes and blood sugar can not be controlled, their blood vessels in the retina will change, which will lead to tiny aneurysms, bleeding, proliferation of fragile new blood vessels and detachments of the retinal tissue. For the treatment, it is proved it will be better to treat retinal complications early so as to reduce the possibility of blindness.

Glaucoma is the third main reason for blindness. High eye pressure is traditionally regarded as the cause for glaucoma, but recent researches show that a circulatory problem to optic nerve death and neurological degenerative disease can cause glaucoma. If this is true, and then we can protect ourselves from glaucoma or control glaucoma by taking care of the nerve health and increasing our blood circulation.

The above are three leading causes for blindness. But as for how to prevent ourselves from blindness, eye doctors and optometrists have done a lot of researches. It is proved the following methods will be good for saving our eyesight: First, healthy diet will be helpful for us to keep good eyesight.
