Why does myopia worsen in low light? What is the reason?

People with normal vision also have a series of adjustments when entering a dim environment, such as dilated pupils. It is normal for people with myopia to have worse eye accommodation. An eye examination should be done every year, and if there is a change in the degree, it should be adjusted in time to avoid increasing the burden on the eyes.

Eyes are used in dim light for a long time, which can cause myopia. As for whether the light is a little strong or a little weak and good for the eyes, it generally varies from person to person, and of course don't go to extremes. Some people are sensitive to light and can feel harsh if it is too strong; Some people are used to bright light, and darkness makes people feel uncomfortable.

<> best light should be bright and soft. If the light is too bright and too dark, and the eye time is too long, eye diseases such as trichiasis, ptosis, keratitis and other eye diseases are not diagnosed in time and **, it will aggravate myopia, and the medical community also has some other opinions, myopia is related to the lack of trace elements such as contour contours, or is related to excessive carbohydrate intake in children, but these have not been conclusively confirmed. People's eyes do not mature until they are around the age of 20, and teenagers' eyes are in the developing stage, and there is a high chance of myopia or myopia progression.

Relatively speaking, the visual state of adults should be relatively stable, but looking at the computer, reading for too long, and long-term eye fatigue make it common for adults to deepen myopia. Arrange your time reasonably, reduce the use of electronic products, and increase the time for outdoor activities. The protective effect is not related to exercise, but to exposure to outdoor conditions, such as 2 hours per day or 10 hours per week.

The effect of increasing outdoor activities on children with myopia is not as pronounced as that of children without myopia. Studies have shown that the protective effect of myopia is related to the amount of time spent outdoors in the sun. At least 2 hours of light per day can prevent the occurrence of myopia and delay the progression of myopia.

Exposure to the outdoors for 19 hours per week can counteract the effects of intense myopic activity. Even if both parents have myopia, 10 hours of outdoor exposure per week can still protect the eyes, and the risk of myopia in children is relatively low.

Myopia is a loss of distance vision, near vision is normal, and as the refraction increases, visual acuity decreases significantly. The darker the light, the worse the ocular accommodation, which will aggravate the development of vision.

Problem analysis: High myopia may have some effects on the inside of the eye, and there are three common complications: floaters, macular hemorrhage, and retinal detachment. These conditions can lead to photophobia and decreased vision.

Suggestions: You need to go to the ophthalmology department of the regular Yebi Good Medical Song Lead Hospital to do a slit lamp examination, optometry, intraocular pressure measurement, etc., it is recommended to go to the hospital Huiqin regularly for a fundus examination, and find out the cause after the examination**.
