Recently, a study published by the National Institutes of Health pointed out that those who sit more than seven hours a day have a 20% higher risk of cataract than those who sit less than three hours a day. The thermal energy released from mobile phones and flat screens can hurt eyes, which may cause cataract and age-related macular lesions to report early.
turn off the light and play with your mobile phone, and you are prone to a variety of eye diseases.
The font on the electronic screen is relatively small, and the light source on the screen is stronger than natural light. Staring at it for a long time is bound to increase visual fatigue.
Whether it is a mobile phone, tablet computer, notebook computer or e-book, they are all electronic products with screens and can emit light. In normal times, this light is not particularly prominent in natural light. If it is in the dark, the background light of the electronic screen will appear dazzling, and the human eye will form a huge contrast between the screen light and the dark environment. In the long run, it can lead to myopia, dry eye, chronic conjunctivitis and so on.
There is a glaucoma inducing experiment in the hospital. Patients lie down in the dark laboratory. If it is glaucoma, it can occur within two hours.
On the contrary, people with short eye axes and thick lenses can also cause glaucoma if they look at light in the dark for about two hours.
How do mobile phone users protect their eyes
1. Provide background light appropriately
When using electronic products, first of all, the light entering the eyes should not be too strong. Some children hide in the quilt to look at their mobile phones. When the contrast is too strong, it will be more harmful to their eyes.
No matter watching TV, computer or mobile phone, it’s better to adjust the brightness of electronic products to a comfortable level and provide yourself with a certain background light. The background light source cannot be directly directed to the eyes or the screen of electronic products, otherwise it will cause light reflection.
2. Maintain distance and control time
Generally speaking, when reading a book or using a mobile phone, 33 to 40 cm is a suitable reading distance; When using the computer, the distance between the eyes and the screen is 60 cm, and when watching TV, the distance is better than 3 meters. It is best to stop after 45 minutes (no more than 1 hour at most) of using electronic products, and let your eyes rest for 10 to 15 minutes, so that you can look at the distance 5 meters away or close your eyes to refresh yourself.
In addition, long-term use of electronic products may increase the chance of retinal macular degeneration in children in the future. At present, most of the eye drops on the market to eliminate fatigue contain mydriasis. Older people can’t use them casually, otherwise they may cause glaucoma.
3. Eat more antioxidant vitamins
Vitamin C and E can eliminate the abnormal accumulation of oxides in the human body and avoid tissue damage. If the human body lacks these vitamins, early-onset cataract will appear in the eyes. You can take more dark green vegetables and various fruits to supplement vitamin C. In addition, you can get enough vitamin E from plant seeds, such as peanut, walnut and pine cone.
