Normal structure of the eye
Cataract causing blurry image

What is cataract?
Cataract is clouding of the normally clear lens of your eye

What is lens?
Part of the eye that helps to focus light, or an image, on the retina. It is CLEAR

What causes cataract?
Mainly long-term exposure to ultraviolet light (sun)

Effects of cataract?
Clouded, blurred or dim vision

Who has cataract?
50% of 65year olds
70% of 75 year olds

Prevention better than cure, how?
Ultraviolet-protective sunglasses

I remember clearly the words of my honourable Professor in Ophthalmology (eye specialist).

"Cataract is a leading cause of visual impairment in the elderly and can be EASILY prevented by wearing UV protective sunglasses! Elderly people didn't have the chance to wear sunglasses in the past, hence they succumb to cataract now. You youngsters should wear sunglasses as often as possible to prevent cataract!"

Those words remained in my mind till now, and I'm sure you'll benefit from this sharing!
