#40. 1. Presbyopia 2. Color blindness 3. Myopia 4. Night blindness 5. Long-sightedness Select the correct codes form options given below:

Solution
C
A person with myopia or near-sightedness can see nearby objects clearly but cannot
see distant objects distinctly. In a myopic eye, the image of a distant object is formed
in front of the retina and not at the retina itself. A concave lens of suitable power will
bring the image back on to the retina and thus the defect is corrected.
A person with hypermetropia can see distant objects clearly but cannot see nearby
objects distinctly. This is because the light rays from a close by object are focused at
a point behind the retina. This defect can be corrected by using a convex lens of
appropriate power.
Aged people often find it difficult to see nearby objects comfortably and distinctly
without corrective eye-glasses. This defect is called Presbyopia. Sometimes, a person

may suffer from both myopia and hypermetropia. Such people often require bi-focal
lenses.
Both Color blindness and night bl

Statement 1 is correct.
It is because of the fact that the force of gravity is stronger on heavier objects than
lighter ones. It can also be explained that the gravity has to pull harder on a heavy
object than a light one in order to speed them both up by the same amount, as it
accelerates everything at exactly the same rate, g.
