Passage: Low vision is a lesser-known but widely prevalent eye problem in India. While more than 28 million people in India suffer from low vision in our country, many people do not realize that they have this problem. Low vision people are neither blind nor do they have full vision. Technically speaking, they score less than 6/18 on visual acuity, and their field of vision is restricted to 10 degrees or less. The people who cannot see very well but whose vision is not helped by the normal glasses are often those suffering from low vision.

Assumption: It is possible to detect cases of low vision by using scientific techniques.​
