People are still young, but their eyes are getting old. For most people aged 40-50, they are beginning to face the dilemma of "early visual aging". With the changes in modern lifestyles, the needs of the elderly for close-up use of their eyes are getting higher and higher, and presbyopia and cataracts are gradually becoming the "new bottleneck" in the lives of middle-aged people. What causes presbyopia ? Presbyopia, also known as "old eyesight", begins to occur around the age of 40 and is common in middle-aged and elderly people. According to Cao Xiangrong, director of Tianjin University Aier Eye Hospital, as people age, the lens in the eye gradually hardens and the ciliary muscle function gradually decreases , causing the eye's accommodation function to decline, leading to a decline in the ability to focus at close distances, resulting in difficulty seeing close objects. In addition to age, factors such as personal physical fitness, reading habits, eye refractive state, and living environment may all affect the severity of presbyopia. It is not a disease, but a natural decline in the human eye's ability to adjust, a normal functional degeneration . Typical symptoms of presbyopia!
Causes of Cataracts The main reason for cataracts in middle-aged and elderly people is that the lens is aged or the disease itself causes lens metabolism disorder, resulting in lens opacity. However, lens opacity cannot be reversed. The current treatment for cataracts is to replace the opaque lens with a transparent artificial lens through surgery. Most people with presbyopia choose to wear reading glasses to improve their vision, but it should be emphasized that presbyopia also has degrees, and professional ophthalmological examinations are required to choose appropriate reading glasses according to vision conditions . Like cataracts, presbyopia can actually be treated with surgery. Presbyopia cataract surgery can solve the problem of cataracts while also solving the problem of presbyopia by implanting refractive artificial lenses, providing patients with better vision at all distances, near and far. After the surgery, they no longer need to wear reading glasses, and it has become a more popular choice for more and more middle-aged and elderly people. However, any method needs to be considered comprehensively based on the actual situation and combined with the doctor's advice to choose a plan that is more suitable for you. |
