• B. The most comfortable distance at which one can read with a normal eye is about $50cm$
• C. If still images of a moving object are flashed on the eye at a rate faster than $16/s$, then, the eye perceives this object as moving
• D. Eye lens becoming cloudy is called cataract

Answer 1

Answer: (B)

The most comfortable distance at which one can read with a normal eye is about $50cm$

If still images of a moving object are flashed on the eye at the rate faster than $16/s$, then the eye perceives the object as moving.

Iris is responsible for characteristic colour of our eye.

The minimum distance at which objects can be seen most distinctly is called the least distance of distinct vision or near point of eye.It is $25cm$ for a young adult with normal eye.

In cataract, the eye lens becomes hazy or cloudy.
