Cataract is a condition where the natural lens of the eye becomes cloudy, leading to blurred or reduced vision.
Simple Explanation
Normally, the eye’s lens is clear and helps focus light onto the retina so we can see clearly.
In cataract, this lens loses its transparency, making vision look:
- Blurry

- Like looking through a dirty glass
