Question

___ is the ability of eye lens to change its focal length to form sharp images.

• A. Accomodation
• B. Range of vision
• C. Dispersion
• D. None of these

Answer 1

The correct option is A Accomodation

The ability of the eye lens to adjust its focal length is called accommodation. However, the focal length of the eye lens cannot be decreased below a certain minimum limit. The minimum distance, at which objects can be seen most distinctly without strain, is called the least distance of distinct vision. It is also called the near point of the eye.
