Question

The normal eye which can sufficiently refract light rays from an object 20 ft. (6 mt.) away to focus clear object on retina is called as

• A. Myopic
• B. Emmetropic
• C. Hypermetrophic
• D. No specific name

Answer 1

Answer: (B)

Emmetropic

A myopic eyed person focuses the light rays from a distant object in front of the retina, it can not focus distant objects sharply on the retina. Emmetropic eyes are characterized by sharp focusing of parallel light rays from distant objects on the retina when the ciliary muscle is completely relaxed to make the person see all the distant objects clearly. Hypermetropic eyes can not sufficiently bend the parallel light rays from the distant object to focus it on the retina in time.
