Clouding of the natural lens of the eye, causes the vision to become blurry.
Cataracts are when the lens, a small transparent disc inside your eye, develops cloudy patches. Over time these patches usually become bigger causing blurry, misty vision and eventually blindness. When we’re young, our lenses are usually like clear glass, allowing us to see through them. As we get older, they start to become frosted, like bathroom glass, and begin to limit our vision.
If your cataracts aren’t too bad, stronger glasses and brighter reading lights may help for a while. But cataracts get worse over time, so you’ll eventually need surgery to remove and replace the affected lens. Surgery is the only treatment that’s proven to be effective for cataracts.
