What is cataract, how it does effect the humans and what are the steps to cure cataract. Does it only attacks humans or also animals?

Question

The lens inside the eye works much like a camera lens, focusing light onto the retina for clear vision. It also adjusts the eye's focus, letting us see things clearly both up close and far away. The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and gets light pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see. No one knows for sure why the eye's lens changes as we age, forming cataracts. But certain factors that may cause cataracts or are associated with cataract development. Besides advancing age, cataract risk factors include: ?Ultraviolet radiation from sunlight and other sources ?Diabetes ?Hypertension ?Obesity ?Smoking ?Prolonged use of corticosteroid medications ?Statin medicines used to reduce cholesterol ?Previous eye injury or inflammation ?Previous eye surgery ?Hormone replacement therapy ?Significant alcohol consumption ?High myopia ?Family history One theory of cataract formation that's gaining favor is that many cataracts are caused by oxidative changes in the human lens. This is supported by nutritional studies that show fruits and vegetables high in antioxidants may help prevent certain types of cataracts.- Prevention of Cataract Although it iss still a debate if Cataract can be prevented but a number of studies suggest certain nutrients and nutritional supplements may reduce your risk of cataractsSome studies have shown that higher dietary intakes of vitamin E and the carotenoids lutein and zeaxanthin from food and supplements were associated with significantly decreased risks of cataract.Good food sources of vitamin E include sunflower seeds, almonds and spinach.-Good sources of lutein and zeaxanthin include spinach, kale and other green, leafy vegetables.--Other studies have shown antioxidant vitamins such as vitamin C and foods containing omega-3 fatty acids may reduce cataract risk.Another step you can take to reduce your risk of cataracts is to wear protective sunglasses that block 100 percent of the sun's UV rays when you are outdoors
