. Myopia occurs due to
A: Increase in the focal length of eye lens
B: Decrease in the distance between retina and lens
C: Decrease in the focal length of the eye lens
D: Increase in the distance between retina and lens
- The term "myopia" is used to describe nearsightedness.
- Before reaching the retina, light from a distant object produces a picture.
- This is due to the eyeball being too big or the cornea or crystalline lens being overly strong.
- The focal length of the eye lens decreases as a result, but the distance between the retina and the lens remains constant.
Hence, option C is correct, i.e., Decrease in the focal length of the eye lens.
