FACTORS AFFECTING CLARITY OF SIGHT

Answer 10

1. Physical imperfections
2. ingested foreign substances
3. Environmental factors

Question 11

occurs at the point where the optic
nerve enters the retina (between the rods &
cones).

Answer 11

Blind spots

Question 12

is caused by
a shorter-than-normal
eyeball which means
that the image is formed
behind the retina .

Answer 12

Hyperopia

Question 13
