Hyperopia, also known as farsightedness or presbyopia, occurs when the eye's axis is shorter, causing the focal point of parallel light rays to fall behind the retina without accommodation. This results in a blurry image on the retina. To see distant objects clearly, the eye must use accommodation to move the focal point from behind the retina onto it, leading to frequent eye strain. In Traditional Chinese Medicine, hyperopia falls under the category of "fear of the near in the distant." The condition is related to the liver and kidneys. It is often caused by a deficiency in yin, which leads to a lack of nourishment for the eyes, or by insufficient innate endowment or deficiency in both liver and kidneys, causing the light in the eyes to disperse and not focus properly, resulting in difficulty seeing nearby objects.
Yin Jing Deficiency Type: The ability to see distant objects clearly but not near ones, difficulty in maintaining continuous vision, with prolonged viewing leading to soreness in the eyes and forehead pain, and increased dizziness. There is also a persistent dryness and fatigue in the eyes, empty pain in the head, accompanied by dizziness and tinnitus, and soreness and weakness in the waist and knees; the tongue is red with little coating, and the pulse is deep, thin, and weak.
Gallbladder Damp-Heat Type: Clear vision at a distance but blurred vision at close range, accompanied by dizziness, deafness, headache, and eye discomfort that worsens with prolonged viewing. Overexertion of the eyes leads to increased fatigue and soreness, sometimes with nausea, vomiting, irritability, and easy anger, bitter taste in the mouth, redness of the sclera, and dark yellow urine; the tongue is red, the coating is yellow, and the pulse is tight, slippery, and rapid.
Yin and Yang Deficiency Type: Eyes are deviated, vision is reduced, and both distant and near vision are blurred and unclear, especially for near vision, which cannot be endured for a long time. Forcing the eyes to work for a long time leads to pain and discomfort in the head and eyes, and double vision may occur. It is often accompanied by dizziness, tinnitus, sore waist, weak legs, and cold limbs; the tongue is pale, and the pulse is thin and weak.
It is recommended to perform moxibustion once a day, targeting 2 to 3 acupoints each time, with each acupoint being treated for 30 to 40 minutes. Rotate the points treated, with a 10-day period constituting one course of treatment, and then rest for 2 to 3 days before continuing with the next course. (If time permits and there is a need, more acupoints can be treated with moxibustion. The specific duration should be adjusted according to one's own physical needs.)
1. Individuals with mild hyperopia generally do not need glasses, but those with symptoms of visual fatigue or who develop strabismus should have glasses prescribed as soon as possible for correction. 2. For children with moderate hyperopia before school age, it is important to have an eye examination and glasses prescribed as early as possible. As they grow older, they should have their eyes re-examined annually and the strength of their lenses reduced in a timely manner to meet the needs of their increasing visual acuity.
