Refractive Errors | MCQs

Explanation

Short-sightedness is caused due to elongation of the eyeball

 It also may result when the curve of the cornea is too steep. 

The messages sent from the retina to the brain are perceived as blurry

Explanation

Long-sightedness is also known as hyperopia.

It is a vision defect where the image is formed beyond the retina, rather than directly on it.

This occurs when the eyeball is too short or the cornea is too flat, causing light to focus at a point behind the retina.

As a result, close objects appear blurry, while distant objects may remain clear.
