Elderly people with visual acuity of 1.0 and above are considered to be in the normal range. Elderly vision, like adult vision, must be 1.0 and above in order to be considered normal, but as we age, degenerative eye disease occurs, so many elderly people develop eye diseases that lead to vision loss. For example, age-related cataracts, age-related macular degeneration, presbyopia, etc. can cause different degrees of vision loss. If you notice symptoms such as vision loss and blurred vision in your daily life, you should go to the hospital for a detailed specialist examination to clarify the cause of vision loss. If it is caused by age-related cataract, cataract surgery can be performed if the vision is seriously affected; if it is caused by age-related macular degeneration, it can be treated with intravitreal injection of anti-VEGF drugs; if presbyopia seriously affects the vision, it can be corrected with glasses. Elderly people should pay attention to the changes in vision, develop good eye habits, such as vision loss should go to the hospital in a timely manner, consult the doctor for the next step in the treatment.
