Answer 1

The correct option is B

Myopia

This defect is short-sightedness or myopia. This is either due to the fact that the eyeball is lengthened from front to back or the lens is too curved. This leads to blurred distance vision, while close vision is usually normal. It is a very common problem that can be corrected by glasses or contact lenses, or cured with laser eye surgery. Night-blindness is a condition in which a person feels difficulty in seeing in dim light or during the night. Hyperopia(Long-sightedness) is a condition in which a person feels difficulty in seeing near objects while in colour blindness colours cannot be discriminated.
