Are you aware of the disease called Cataract? Cataract is a disorder that is progressive and painless creating a layer on natural, internal lens of the eye, behind the iris and the pupil. It blocks the light entering our eyes and makes it difficult for us to see. It can also result into blindness if not cured in a certain period of time. This problem is generally caused to people above the age of 40. But in some cases it may develop in younger people. According to Prevent Blindness America (PBA), more cases of cataract have been found than that of Glaucoma, macular degeneration and diabetic retinopathy combined.
What Causes Cataracts?
Just like the functioning of camera, the eye lens also focuses light onto the retina for clear vision. It adjusts the eye’s focus, letting us see things clearly both up close and far away. Water and protein is what the lens is actually made up of. The protein is arranged in a precise way that keeps the lens clear and let’s light passes through it.
These proteins start to cloud a small area of the lens in the form of clumps due to age factor. And this might grow bigger and cloud more eye lens, making it difficult to see.
Besides advancing age, cataract risk factors include:
Types of cataracts include:
Certain nutrients and nutritional supplements may help you reduce the risk of cataracts. In order to decrease the risk of cataract, higher dietary intake of vitamin E and the carotenoids lutein and zeaxanthin from food and supplements is essential.
Cataract may also be reduced with antioxidant vitamins such as vitamin C and foods containing omega-3 fatty acids as shown in other studies.
