What is the eye defect shown in the picture below?
The correct option is a)Myopia.
- Nearsightedness or myopia is an eye condition caused by a refractive error that causes distant objects to appear blurry. A nearsighted person can clearly see nearby objects.
- Myopia means that the focus of the eye is in front of the retina instead of on it. The retina is the surface at the back of the eye that collects light.
- It converts light into electrical impulses that the brain interprets as images. Blurry vision can occur when the eye focuses light in front of the retina.
