In this case, vision becomes out of focus at any distance. In addition, the curvature of the lens inside the eye can change, resulting in an increase or decrease in astigmatism as well. This change frequently occurs in adulthood and can precede the development of naturally occurring cataracts also. http://vishwashospital.com/
