Recently, a report by Canada's ValleySun website stated that even if a person has excellent vision in their youth, they still need to wear glasses to improve their vision around the age of 40; hearing loss generally occurs after the age of 50, and it often affects men earlier than women. This is similar to physical strength; even if one maintains regular exercise and a balanced diet, it becomes difficult to have the same strength and speed as in their 20s after turning 40. This is the normal process of human aging.
Wang Lihua, an ophthalmologist from the 306th Hospital of the PLA, stated in an interview with reporters that after the age of 40, the body's various organs undergo degenerative changes.
The problems with the eyes are mainly manifested in the gradual decline of eye muscle strength, hardening of the lens nucleus, and reduced elasticity. The human eye's ability to focus on nearby objects relies on the ciliary muscle's adjustment. This ability gradually weakens with age, making nearby objects appear increasingly blurry. By the age of 48, the eye's accommodative power for near vision is no longer sufficient, which is the origin of the Chinese proverb "At forty-eight, vision starts to fade."
So, can the onset of presbyopia be delayed? Wang Lihua frankly stated: strengthening physical exercise and improving one's own resistance are the best ways to delay overall aging. Locally, you can also promote blood circulation in the eyes by frequently doing eye exercises and applying hot compresses. Additionally, drinking a cup of goji berry and honey water every morning can also have a certain effect in delaying presbyopia.
Regarding the decline in hearing, Xu Anting, chief physician of the Department of Otolaryngology at Qilu Hospital of Shandong University, told reporters that although it cannot be determined why men experience hearing loss at an earlier age than women, for both men and women, to delay hearing loss, one can achieve this by eating a light diet, consuming less animal fat and offal, maintaining a cheerful mood, strengthening physical exercise, and massaging the ears frequently. Traditional Chinese medicine believes that the kidney opens to the ears, so one can appropriately consume more kidney-nourishing foods, such as walnut porridge, sesame porridge, and peanut porridge.
