Usher Syndrome

Like the previous problem, this is a genetic problem as well. This problem comes with hearing loss also. Altered or mutated genes are responsible for this problem.

Light isn’t focused properly in that case and vision becomes blurred. As a result, you will feel discomfort and headache. Most people have this vision condition to some extent and the reason isn’t specified till today. Genetic conditions may be the reason behind it.
