World Health Organization research shows that 80% of all vision damage can be prevented and cured, so it is especially important to pay attention to protecting your eyes in life.
Put a humidifier next to the computer
Staring at the computer screen for too long, the eyes will feel fatigue and dryness, which is a lot of people's suffering, but scientists have not known the reason for it. Research published in the Journal of the American Medical Association - Ophthalmology shows that people who work on the computer for seven hours or more a day have significantly less tear production than the average person.
Researchers at Keio University in Japan also found that the composition of tears changes when looking at screens for long periods of time, and that the concentration of one of the mucins (MUC5AC) that can adequately wet the eye decreases. Reduced tear production and changes in composition cause symptoms somewhat like the eye symptoms of dry syndrome, making people very uncomfortable, as if the eyes into the sand or foreign objects, and in severe cases, photophobia and redness. Modern office can not be separated from the computer, in order to protect the eyes, may be placed next to the computer screen a humidifier, in addition to avoid the air conditioning vents directly to the eyes.
A cup of coffee every day
Cornell University found that an antioxidant in coffee called chlorogenic acid helps prevent the degeneration of the retina. The retina is a transparent membrane within the wall of the eye, which contains millions of photoreceptor cells and optic nerve cells that help our brain collect the images we see and do the initial processing. Once oxidative stress occurs in the retina, free radicals are produced, ultimately leading to tissue damage and vision loss. Glaucoma, aging and diabetes all contribute to the degeneration of the retina. Chlorogenic acid prevents retinal degeneration, and coffee contains up to 7%-9% chlorogenic acid.
Eat more spinach
When people age, their eyes are prone to degenerative diseases such as macular degeneration, and eating more spinach rich in lutein can prevent retinal macular degeneration. The macular region of the retina is where vision is sharpest, and high concentrations of lutein in the macula can protect the eyes from harmful light and maintain a normal blood supply to the eyes. However, the human body cannot synthesize lutein and must take it from food. In addition to spinach, corn, kale, pumpkin and carrots are also rich in lutein. In fact, people of all ages should pay attention to lutein supplementation, which is the equivalent of "invisible sunglasses".
Eat more cold water fish
Omega-3 fatty acids not only protect our heart, but also our eyes. Omega-3 fatty acids promote the development of infants' eyes, and research at Harvard Medical School shows that formula with DHA (an omega-3 fatty acid) can significantly enhance the vision of infants from 2 to 4 months of age. DHA supplementation for mothers during pregnancy also helps babies' vision later in life. Adults can take more omega-3 fatty acids to prevent age-related macular degeneration and dry eyes, and to reduce the risk of glaucoma. Cold-water fish such as salmon are a good source of omega-3 fatty acids, as are dark green vegetables and pecans. You can also take dietary supplements of omega-3 fatty acids.
Eat less sweets
When metabolizing sugar, the body needs to consume large amounts of vitamin B1. The vitamin is an important element involved in and maintains the function and metabolism of the optic nerve cells. When vitamin B1 is insufficient, we may feel dry eyes and even develop optic neuritis. Therefore, in order to protect the optic nerve, one should eat less sweets, while lean meat, peanuts, corn, millet, nuts and mushrooms are all foods rich in vitamin B1 and can be eaten in abundance.
Wear sunglasses
Wearing the right sunglasses can protect your eyes from UV rays. Receiving too much UV rays can increase your chances of developing cataracts and macular degeneration. Sunglasses that filter out 99% to 100% of both UVA and UVB can help protect your eyes. Lenses with curves prevent harmful rays from entering your eyes from the sides, and polarized lenses are best for wearing while driving. Some contact lenses have their own protection against UVB rays, but it is best to wear additional sunglasses to give your eyes complete protection.
Wearing protective glasses
If you have to stay in heavily polluted air for long periods of time because of your job, then be sure to wear goggles or protective glasses to prevent infectious eye diseases. When playing sports that are prone to eye injuries such as hockey, squash, and field hockey, you should also do a good job of protecting your head and eyes.
Don't order more eye drops
The computer workers, in order to relieve eye fatigue and dryness, do not move to order eye drops, in fact, this is not good. As long as the eye drops are not disposable, they contain preservatives, which are not harmful to the eyes in the short term, but to use them for a long time, it may cause damage to the cells on the surface of the conjunctiva and cornea, and over time, the secretions of these cells will be reduced. Therefore, ordering eye drops can relieve dry eyes in the short term, but long-term use can aggravate dryness. If you really suffer from dry eyes and need to order artificial tears for a long time, then you can buy disposable ones, which are more expensive but do not contain preservatives.
