Symptoms take time to show their effect.

What are Cataracts?

The inside of the eye which is the clean lens helps the light to enter and images are projected on the retina which is at the back of the eye. With time, the inside of the eye will break down and stick together. Due to this, it will form yellow, white, or brown clumps which distort the vision, block the vision, and create a cloud. In medical terms, these are referred to as cataracts.
