Some people are just over 40 years old, wearing a depth of presbyopia, while there are also elderly people, although over the age of old but deaf, the degree of blurred eyes progress very slowly, and even do not wear presbyopia can also read books and newspapers. The reason for this, in addition to the congenital quality has a certain relationship, is mainly the usual self-care to have a square.
The so-called “presbyopia” refers to people who are older and gradually have difficulty reading or working at close distances. This is a phenomenon of the aging of human body functions. Presbyopia is also known as presbyopia, mostly seen above the age of 40, the lens hardens, elasticity decreases, the ciliary muscle contraction ability decreases and the adjustment decreases, the near point is far away, so the occurrence of near distance vision difficulties, this phenomenon is called presbyopia. In fact, presbyopia is a normal phenomenon in human physiology, and is a signal that the body is starting to age. As we age, the lens of the eye gradually hardens and thickens, and the adjustment ability of the eye muscles also decreases, resulting in reduced zooming ability. As a result, when looking at close objects, seeing close objects becomes blurry because the image is not fully focused when projected on the retina. Even with careful eye protection, the degree of presbyopia increases with age, generally at a rate of 50 degrees every five years. According to the table corresponding to age and eye presbyopia, most people with good refractive conditions, i.e., no myopia or hyperopia, usually have 100 degrees of eye presbyopia at the age of 45, increasing to 200 degrees at the age of 55, and increasing to 250 to 300 degrees at the age of 60, after which eye presbyopia generally does not deepen.
Presbyopia is often taken as a sign of old age, and many people in their early forties have presbyopia and refuse to wear presbyopic glasses to correct their vision because they don’t want to be old, which in turn increases the burden on their eyes. If you don’t wear glasses, even if you can barely see the near side of the target, you will have all kinds of eye fatigue due to forced adjustment and excessive contraction of the ciliary muscle, such as headaches, tight brows, eye pain, blurred vision and other vision fatigue symptoms.
According to Chinese medicine, presbyopia is caused by the gradual decline of qi and blood when people get older, and the loss of liver and kidney essence, which prevents them from nourishing their eyes. If you can pay attention to eye care, further vision loss can be prevented or delayed. From the perspective of Chinese medicine, foods that strengthen the spleen, nourish the liver and nourish the kidneys can be taken. Foods for the spleen include celery, taro, potatoes, lotus root, bamboo shoots, eel, cinnamon, grapes, hawthorn, yam, sweet potatoes, lentils, cowpeas, etc. Foods for the liver include lamb liver, snapper, turtle, mulberry, duck, etc. Foods for the kidneys include lamb, yellow fish, sea cucumber, nori, shrimp, walnuts, black beans, etc. At the same time should not use spicy, dry, fatty products, do not smoke, do not drink alcohol.
