Question

Give one point of difference between following on the basis of what is given in bracket myopia and hypermetropia (cause of defect).

Answer 1

Myopia and hypermetropia:

1. Myopia is the condition that occurs where distant objects appear to be blurred while the nearby objects are seen clearly. It is also called Short-sightedness.

2. Hypermetropia is where one can’t see close by objects clearly while distant objects appear to be clear. It is also called farsightedness.

Difference between myopia and hypermetropia (cause of defect):

MYOPIA	HYPERMETROPIA
This defect can be caused due to: Increase in the length of the eyeball in front or back. When the lens of the eye becomes curved. The person can see the unclear image of the distant objects. The unclear image of the distant objects formed due to the image presents in front of the retina.	This defect can be caused due to: Shortening of the length of the eyeball. Either from the front or back, If the lens becomes flat and curvature is lost. The focal length of the eye lens is large in size. Eyeballs are small in size.
