But most people will have the symptoms of presbyopia around the age of 50, and some people even begin to have presbyopia around the age of 40, which is generally called "less presbyopia". In fact, presbyopia is a sign of human aging. Generally speaking, when reading a mobile phone, you should use a large font, or when reading a newspaper, you should be a little farther away to barely see it.
Senile cataract is also caused by the gradual aging of the lens with age. More ophthalmologists say that anyone over 80 must have cataracts.
In fact, from the perspective of western medicine, presbyopia means wearing presbyopia correctly, and cataract is generally treated by surgery. But from the perspective of Chinese medicine, health care and prevention are generally emphasized, so today we will talk about how presbyopia and cataract start from prevention.
About preventing cataracts and presbyopia, there are about six tips:
1. Wear sunglasses scientifically.
Sunlight can lead to degeneration of lens protein and opacity of lens, which can lead to cataract. According to past experience, farmers are often more prone to cataract than urban residents, which is the result of their long-term exposure to the sun. If there is long sunshine in an area, people living in that area are also prone to cataracts.
For cataracts, paying attention to prevention when you are young can reduce the incidence of cataracts in the elderly. Therefore, doctors suggest wearing sunglasses in time when the sun is strong, and it is best to choose sunglasses that can really prevent ultraviolet rays.
2. Don't dehydrate yourself.
When the human body is dehydrated, the metabolism of liquid in the body is disordered, which will produce some abnormal chemicals, damage the lens and lead to cataracts. For existing cataract patients, dehydration will aggravate the condition. Therefore, once you encounter diarrhea, vomiting, sweating, etc. caused by various reasons, you should replenish water in time. You only need to drink boiled water and tea at ordinary times, and so does presbyopia.
3. refuse to use your eyes too much for a long time.
With the popularity of mobile phones, not only young people like to play mobile phones, but even the elderly are no exception. However, with the increase of age, the eyesight adjustment function of the elderly will decline, and it is more necessary to pay attention to excessive use of eyes. If the eyes are always in a state of fatigue, blurred vision will appear over time, which will eventually lead to the advance and aggravation of presbyopia and cataract.
4. Pinch your wrist and see clearly.
The senile point has the functions of clearing the brain, improving eyesight, relaxing muscles and activating collaterals. Pressing this acupoint often is good for relieving myopia and presbyopia.
Acupoint selection: look at the little finger side of the wrist with the back of your hand up, and the protruding part of the bone can be seen with the naked eye. Touch this part with your fingers, and you can touch the crack, and the pension hole is in the crack. You can press your finger 10 to 20 times every morning and evening. If you press it repeatedly with your fingers for about 3 months, the pain at the acupoints will disappear and the eye diseases will slowly ease.
5. Pinching your thumb can inhibit cataracts.
There are three adjacent acupoints on our thumb, namely, the bright eye, the eye of the wind and the hollow valley.
This group of acupoints are located on both sides and in the middle of thumb joint respectively. Yan Ming and Yan Feng can improve acute conjunctivitis and inhibit senile cataract. People with tired eyes usually stimulate these three acupoints twice a day as long as they feel slight pain.
6. Small methods in daily life.
Blinking often can exercise eye muscles and relax eyes; Hold your head in your hands and rub your scalp everywhere. You can also beat drums, that is, beat your head with your fingers. In addition, usually wash your face and eyes with cold water, let your eyes keep turning in the water, and dry them after repeated several times. Then gently rub the face and eye muscles with your hands for 20-40 times. Long-term persistence has a good effect on preventing presbyopia and cataract.
