Question

Range of vision for a normal healthy human eye is

• A. from the eye to infinity
• B. up to the least distance of distinct vision
• C. from infinity to the least distance of distinct vision
• D. none of these

Answer 1

The correct option is C

from infinity to the least distance of distinct vision

The explanation for the correct answer,

1. The normal healthy human eye has a near point of $25cm$ from the eye lens. It is known as the least distance of distinct vision.
2. The normal healthy human eye has a far point at infinity.
3. Thus, the range of vision for a normal healthy human eye is between the least distance of distinct vision and infinity.

Thus, the correct option is (c).
