The eye is the sensory organ most rapidly affected by the aging process. The sense of sight can be affected by age, as well as by some physical and natural changes. As a result, the pupil, called the pupil, which allows the light to fall on the retina, becomes smaller. Adaptation to light slows down and vision difficulties are observed in dim light. As the lens of the eye loses its flexibility, the problem of nearsightedness begins.
Keratoconjunctivitis, known as KKS, or dry eyes may occur. In dry eye, tear volume and function decrease, and the person complains of complaints such as blurred vision, redness and burning. Another age-related eye problem is cataract. In cataract, the adaptability of the lens, which changes in weight and thickness, decreases with age. New fiber layers form around the lens. This compresses and hardens the lens core. In this process, in which the lens core proteins undergo chemical changes, brown and yellow discolorations occur on the lens. Cataract is the most common cause of visual impairment due to aging. It is the most common cause of blindness in the world and the only treatment is the removal of the cloudy lens by operation and replacing it with an artificial lens.
