As we age, there come inevitable changes in our bodies which affect us in different ways.Various things in our body begin to change including the eyes. Our eyes have a crystalline lens which works to focus on things at varying distances. This lens becomes stiff and hardens to some extent, losing its ability to focus properly. With these changes occurring in the natural crystalline lens with passing time, it can possibly lead to cataracts, which is clouding of the ocular lens causing loss of its clarity therefore leading to blurred vision.
