There is a disease in the body, 'eyes' tell? Reminder: If there are 4 abnormalities in the eyes, check them as soon as possible
The 50-year-old Uncle Wang always finds reading books and newspapers very strenuous. His eyes seem to be covered with a dark spot that cannot be wiped off. Always looking for my son, "Help me see, what is written here? Why do I look yellowish, I can't see clearly."
Uncle Wang thought it might be presbyopia. One day he bought reading glasses on the train, but after wearing them, they were still blurry.
The son said that he should go to the hospital to have a look, but Uncle Wang was reluctant to go because he felt that his eyes would also age, so it would be too much of a fuss to go to the hospital.
1. When you get old, you see things becoming more and more blurry. What's going on?
With age, the elasticity of the lens decreases and the ciliary muscles weaken, so it is difficult for the eye to focus and vision becomes blurred. Presbyopia usually starts around the age of 45 and becomes stable by the age of 65 to 70.
But if the eyes are always dark and foggy, don't think it's just aging.
Cataracts are caused by the normal aging of the lens, which becomes blurred when seeing, and the incidence increases with age.
At present, there is no drug that can treat cataracts . Mild cataracts generally do not require special treatment. However, if they develop to the later stage, it is easy to affect vision and even cause blindness. It can be treated by surgery in time under the evaluation of a doctor.
In addition, pay attention to whether it is floaters or vitreous hemorrhage .
Floaters are age-related, manifested as dark shadows in front of the eyes, and generally do not cause visual impairment; however, if vitreous hemorrhage is not treated in time, it may cause retinal detachment and affect vision.
One of the common eye diseases among the elderly is age-related macular degeneration, also known as age-related macular degeneration, which can easily lead to irreversible damage to vision and is also the most important cause of blindness in the elderly . The main manifestations are decreased visual acuity, visual distortion, visual discoloration, central scotoma and so on.
Finally, some chronic diseases can also make eye damage worse, such as older adults with diabetes, and diabetic retinopathy .
2. Poor eyesight, is it useful to eat lutein?
Some elderly people have poor eyesight, so they want to improve the situation by eating lutein, and even spend a lot of money to buy health products containing lutein. Is this really useful?
Dietitian Gu Zhongyi mentioned that an important cause of vision loss in the elderly is age-related macular degeneration. Generally speaking, eating more vegetables and fruits rich in zeaxanthin and lutein can fight against blue light damage and vision. Fatigue , such as spinach, kale, coriander, fish, pistachios, eggs are rich in lutein.
However, the dietary structure of the elderly is often difficult to obtain sufficient active ingredients, and supplements can be chosen at this time.
According to the well-known large-scale clinical trial AREDS II, there is a dietary supplement that can improve age-related macular degeneration. This formula is now popular as a combination of "vitamin C + vitamin E + zinc + lutein + zeaxanthin" .
When choosing supplements, it is recommended to choose a single ingredient as much as possible, and it is better to choose less compound formula, which can reduce the overdose caused by the superposition of drugs. But different people may have great differences, and health food has no effect on treating and encountering diseases.
If you want to test your eyes for "macular degeneration", try the Amsler grid:
Place the square table at a distance of 30cm from the eye level, and the surrounding light is uniform and clear. If you are short-sighted or presbyopic, you need to wear glasses to test, cover one eye with your hand, and stare at the black spot in the middle of the table with the other eye. Then check the other eye in the same way.
If you see C, it means that the macula is normal; if you see A or B, it may be a problem with the macula.
3. These 4 signs appear in the eyes, check them as soon as possible
The eyes can reflect the health status to a certain extent. If you find these abnormal symptoms in the eyes, you should be alert to the possible causes of diseases:
· Yellow eyes
Yellow eyes need to be alert to liver problems, especially obstructive jaundice . Due to complete or partial obstruction of the bile ducts in the liver or outside the liver, bile cannot be discharged into the intestines and accumulate in the liver. If you are also accompanied by symptoms such as fatigue, anemia, and weight loss, you need to be alert to malignant tumors, such as pancreatic head cancer, ampullary cancer, and bile duct cancer.
· Protuberance
The most obvious feature of thyroid-related eye disease is proptosis and retraction of the eyelid, which looks like staring. It involves most of the tissues of the eye, such as orbital fat, extraocular muscles, etc., and affects intraocular pressure, eyelid, and optic nerve. .
Thyroid-related ophthalmopathy often presents symptoms such as dull eye pain, dry eyes, congestion and edema around the eyes, tearing and photophobia, and even severe corneal ulcers and exposure keratitis.
· Pupils are white
White pupils need to be alert to leukoria , that is, the pupils that should have been black become white.
White pupils may be caused by many diseases, such as cataracts, retinoblastoma, Coat's disease, intraocular infection, retinal detachment, etc. These diseases will not only seriously damage the vision, but even be life-threatening, and require timely medical examination.
· Eyelid swelling
Eyelid swelling may be physiological, such as sleeping too low on the pillow, drinking too much water before going to bed, sleeping too long or too short, etc. It usually disappears on its own after 1 hour of getting up.
But it may also be pathological eyelid swelling , such as keratitis, conjunctivitis, kidney disease, anemia, hypothyroidism, heart disease, etc. If persistent eyelid swelling occurs for several days, it is best to seek medical attention in time.
4. Always do 3 things to protect your eyes
The eyes are very important organs. Once injured, they will have a great impact on life. Usually, we can protect the eyes by doing the following things:
1. Do more outdoor sports
Studies have shown that outdoor exercise can effectively prevent eye fatigue . Maintaining two hours of outdoor activities in a sunny place every day, or more than 10 hours a week, can effectively prevent myopia.
2. " 20-20-20 " eye protection principle
Use your eyes moderately and blink more often. If you use your eyes too much, the number of blinks will decrease, and your eyes will be dry, sore, and photophobic due to lack of tear moisture.
To protect eyesight, you can adopt the "20-20-20 eye protection principle", that is, after using electronic products for 20 minutes, you should look at a distance of about 6 meters for at least 20 seconds.
3. Ensure balanced nutrition
In terms of mechanism of action, some nutrients are closely related to eye health.
Vitamin A deficiency, for example , can lead to night blindness. Liver, whole milk, egg yolks, etc. are all good sources of vitamin A.
B vitamins are beneficial for relieving visual fatigue, and can be supplemented by animal offal, milk eggs, beans, whole grains, livestock, poultry, fish and meat;
By consuming nuts, whole grains, meat, seafood, and supplementing minerals such as calcium, zinc, chromium, etc. , the importance of a balanced diet can be seen.
In short, if you always feel that your eyes cannot see clearly, and you have symptoms such as ghosting, dark shadows, and floating mosquitoes, you should go to the hospital for examination to clarify the cause. Pay attention to abnormal eye symptoms, pay attention to moderate eye use, balanced nutrition, and eye protection.
