Recently my eyes became inflamed; actually I have been carrying red eyes for a long time, only I didn't notice it. There is also indication of vitreous opacity. Yet I still feel lucky that my eyesight haven't dropped since college, maybe as a result of sufficient sleep and diet. I plan to buy tea leaves made of medlar, chrysanthemum and others tomorrow and hope they will do good to my eyes. Last week I talked about treatment of myopia with one of my friends. We both thought that current treatments, like femtosecond, laser and quasimolecule, seem to be cutting the feet to fit the shoes. The prblem of refractive errors hasn't been resolved at root, neither has vitreous opacity been treated with effective medication. We hope that modern medicine can put more efforts into curing those eye diseases which are not so difficult to conquer. Stop wasting public money on extravagant dishes and travels. Cherish our eyes and stay awary from ignorance.
1. Alternate work and rest to prevent tendon strain. Using computers for a long time may cause pain in your finger joints, wrists, arm muscles, neck and back. Therefore, computer users should rest for 10 to 15 minutes after 40 to 50 minutes of work. Don't work nonstoppingly for over one hour. Do some exercises during work break.
2. Use your eyes in a healthful way. Keep your eyes at least 50cm away from reading materials or computer screen. Better take a 20-degree downward visual angle. Apply anti-radiation skin cream to your face and hands while using computers.
3. Pregnant women should not use computers for more than 20 hours a week. Long-time sitting can cause unsmooth blood flow, so alternate work and relaxation; adjust the heights of your computer and chair to ensure the healthy growth of the embryo.
4. Those who are long engaged in computer operation should eat more fresh vegetables and fruits. Meanwhile take in more vitamin A, B1, C and E. Computer users should eat food that are rich in vitamin A, such as bean products, fish, milk, walnut, pakchoi, Chinese cabbage, tomato, water spinach and fresh fruit, to prevent cornea dryness, eye dryness, eyesight drop or even nyctalopia. Vitamin C can check cell oxidation effectively while vitamin E can reduce cholesterol, remove intestine waste and prevent cataract. Walnuts and peanuts contain rich vitamin E. The function of Vitamin B1 is to provide more nourishment to nervous cells and ease the tension of nerves.
5. Drink green tea everyday. The lipopolysaccharide contained in tea leaves can improve our bodies' hematopoietic function. Shortly after the body is injected with lipopolysaccharide, its non-specific immunity will improve greatly. Besides, tea leaves can prevent damage from radiation.
6. To avoid reflection or unclearness of the screen, don't place computers in the opposite or at the back of windows; use soft lighting. Draw the curtain if there are windows at the back of the computer user to prevent reflection from causing eye fatigue.
7. Ventilate computer rooms regularly. Install ventilating fan or air conditioner to mitigate the effect of polybrominated dibenzofuran on the body. The dust density around computers is hundreds of times higher than other spaces in the computer room. The dust long adheres to the skin and thus causes various skin diseases. Keep the computer room clean and swab the computers regularly.
8. For the average people, to blink less than 5 times in one minute will lead to eye dryness. A person will blink 2/3 times less than usual while working with computers. As a result, there be less secretion of intraocular lubricant and enzyme. Therefore, computer users should blink more and rest eyes at least once a hour.
