Myopia.
The affected person can see the nearby objects but not the distant objects. This condition may result due to an elongated eyeball or thickened lens, so that the image of distant object is formed in front of the yellow spot. This error can be corrected using concave lens that diverge the entering light rays and focuses it on the retina.
