Aging is always evident with symptoms such as whitening of the hair, facial wrinkles and, of course, the emergence of certain diseases. Cataract or eye opacity is one of the most important cases. Cataracts have a variety of effects on the visual system and, if left untreated, lead to blindness.
Undoubtedly, entering middle age can be an introduction to cataract. This complication typically occurs with aging, although ultraviolet rays of the sun, eye trauma, inflammation, rheumatism, the use of certain drugs and congenital causes have a role in its occurrence, and using tobacco has a greater effect.
For most people, the age range of 65-70 years is considered as the average time of this disease and its probability is predicted to be up to 50%, but from the age of 70 and above this chance increases up to 75% and will be intensified.
From an ophthalmologist perspective, the cataract is a disease caused by the aging of the lens of the eye. In this case, a group of pathologic factors and tissue changes that occur in the cells are interrupted, such that this disease will appear gradually. As a result of this phenomenon, the protein in the eye lens gradually accumulates and causes change. The compression of the lens causes changes in its strength, and the patient becomes nearsighted and long-sighted at times.
