Recently, Shanghai has opened the “high temperature roasting” mode. Faced with the “red alert” of high temperature, our “window of the soul” cannot be ignored, because the eyes are in high temperature. Whether it is indoors or outdoors, it is easy to get injured! So how to protect it?
To this end, Tong Xiaowei, Chief Physician of the Department of Ophthalmology of Shanghai Eye Disease Control Center (Shanghai Eye Hospital), presented a collection of popular science.
What kind of damage is the eyes most afraid of in hot weather?
In high temperature and heat, what our eyes are most afraid of is the damage caused by ultraviolet rays, because strong ultraviolet rays are prone to various eye diseases. So, what are the diseases of the eyes that UV rays are likely to cause?
Macular degeneration is a common blinding eye disease. Excessive exposure to ultraviolet light and other environments causes chronic light loss and is one of the important risk factors for this disease. Increased cataract risk. Ultraviolet rays affect the redox process of the lens, resulting in disorder of lens metabolism, resulting in denaturation of lens proteins and opacification, forming cataracts. Improper light exposure is an important cause of cataract development and blindness. Excessive UV exposure can cause ocular surface disease. Such as pterygium and dry eye, chronic conjunctivitis, corneal damage and so on. Because the eyes are the most direct part of receiving ultraviolet rays, improper protection, the ocular surface will become the first pressure part.
Which groups need to be highly concerned about the hot weather? It is mainly people who work outdoors and exercise a lot, drivers, IT personnel and white-collar workers who work in air-conditioned rooms, and people with existing eye diseases.
The importance of eye protection for the above four groups of people in high temperature weather is no less important than the prevention of “heat stroke” to a certain extent. Future eye health will have an impact.
So how should you protect your eyes?
1. Wear the right sunglasses
Choosing a pair of high-quality sunglasses is a matter of knowledge. When buying sunglasses, be sure to choose lenses marked with UV protection. For sunglasses, the UV index is the effect of filtering out ultraviolet rays, which should be to eliminate the light in the 280-400nm band. At present, the UV index of most sunglasses is between 96% and 98%, and dark lenses are better than light lenses.
Generally speaking, drivers are more suitable for polarized sunglasses. In addition to special effects such as anti-shattering and anti-wear, it can filter out more than 99% of dazzling random reflection light and 98% of ultraviolet rays, which makes the human eye feel more comfortable. Clear and comfortable, not easy to produce fatigue. For people with myopia or astigmatism, a chromatic mirror or tinting mirror with appropriate power can be customized.
The amount of blocking light depends on the color of the lens. The darker the color, the more light is blocked. Blocking ultraviolet rays means adding raw materials that absorb ultraviolet rays to block ultraviolet rays when the lens is in a liquid state. , General regular sunglasses are 100% UV protection that is UV400. Ordinary optical resin lenses are generally anti-UV360 ~ 380, unless there are special instructions to prevent UV400.
2. Choose a comfortable eye lotion
At present, dry eye is also very common in young people in addition to middle-aged and elderly people. To deal with dry eye, the first is to control When using the eyes, pay attention to adjusting and resting; the second is to improve the internal environment of the eyes and make the eyes comfortable by using eye lotion and other eye care products. The combination of these two methods should greatly alleviate the occurrence of dry eye symptoms. A suitable eye lotion is free of preservatives and antibiotics, so as not to cause invisible damage to the eyes during long-term use.
3. Do a good job of daily protection
For patients with macular degeneration and other fundus diseases, it is more important to do a good job of daily protection. Daily oral antioxidants, Supplementing eye nutrients such as lutein is like holding up a protective umbrella on the fundus, increasing the density of macular pigment, inhibiting the development of the disease, and protecting vision.
4. Ensure good work and rest habits
In addition, in the hot summer, we must also make ourselves have a good work and rest habits, ensure sleep, and maintain rich nutrition , remember to drink more water, eat more fresh vegetables and fruits. These are very beneficial to our eyes.
In short, in hot weather, we must learn to use more scientific methods to protect ourselves. In addition to protecting the whole body, we must also close the window of the soul that loves ourselves, so that our eyes are less damaged and we live a peaceful life. summer. Remember to protect your eyes in summer, but it has a multiplier effect!
Only healthy eyes can keep the world bright for a long time in your eyes! In hot weather, please also give your eyes a “high temperature” protection.
At present, the Shanghai Eye Disease Prevention and Treatment Center is doing its best to provide outpatient medical services in the two campuses of Kangding Road and Hongqiao Road. In response to the needs of summer students, the prevention and treatment of myopia in children and adolescents, the “mirror removal” of myopia surgery for high school students, etc., are provided for young white-collar OPT dry eye treatment, cataract surgery for middle-aged and elderly groups, retinal detachment surgery, macular edema injection treatment, etc. Special outpatient clinics and Expert outpatient clinics to solve the eye problems of patients visiting the clinic at any time.
