Side effects of myopia table in Shanghai Eye Hospital
Myopia is a common vision problem. The patient's eyeball is oval and cannot focus on distant objects correctly. Myometer is a commonly used method to treat myopia. Wearing a myometer can improve vision problems. However, there are also some side effects of the use of myopia watches. This article will elaborate from four aspects: eye fatigue, vision dependence, corneal deformation, and decline in adaptability.
Eye fatigue
Wearing a myopia watch for a long time will easily lead to eye fatigue. Because the lens in the myopia table refracts the distant light, the eye needs more adjustment to adapt to different focal lengths. This long-term eye adjustment work will make eye muscles overuse, which is prone to eye fatigue symptoms, such as dry eyes, itchy eyes, blurred vision, etc. In addition, the number of blinks will be reduced when wearing a myopic watch, resulting in dry eye surface and further aggravating eye fatigue.
In order to reduce eye fatigue, people who use myopia watches should take regular breaks, especially those who stare at the electronic screen for a long time. At the same time, keep the indoor light moderate to avoid eye fatigue.
Visual dependence
People wearing myopia watches are prone to rely on lenses, leading to a decline in naked eye vision. This is because the myopia table provides a focusing force suitable for the eyes, but long-term dependence on the myopia table will lead to the loss of the eyeball's ability to adjust its own vision, thus reducing the naked eye vision. In particular, children wearing myopia watches are likely to affect normal visual development.
In order to avoid visual dependence, people who use myopia tables need to regularly carry out naked eye vision training, such as outdoor long-distance eye movement, and try to reduce the time of using eyes in short distance. Parents should also guide their children to use myopia watches correctly to avoid excessive dependence.
Corneal deformation
Wearing a myopia watch for a long time will also cause certain pressure on the cornea, leading to corneal deformation. Cornea is the transparent tissue of the outer layer of the eye, which directly affects vision. The myopia table will generally increase the corneal shape of the eye, thus improving vision problems. However, if the myopia watch is worn for a long time, the cornea may flatten or become thin, increasing the risk of patients suffering from corneal foreign body sensation, dryness and other uncomfortable symptoms.
Therefore, people who use myopia tables need to regularly check the health of their eyeballs in eye hospitals to avoid discomfort caused by corneal deformation. The doctor will also adjust the wearing time and degree of the myopia watch according to individual conditions to reduce the pressure on the cornea.
Decrease in adaptability
The use of a myopia watch may reduce the ability of the eye to adapt to a long distance. Because the myopia watch provides a focusing force suitable for the eyes, the eyes will adapt to the focal length after long-term wear, thus reducing the ability to adapt to a long distance. This will make the patient have poor vision after taking off the myopia chart, and it will take some time to adapt to the naked eye sight distance.
In order to avoid the decline of adaptability, people who use myopia watches can try to gradually reduce the wearing time and increase the time of naked eye sight distance training. It is also necessary to go to the ophthalmic hospital regularly for reexamination, so as to adjust the use of the myopia table in time.
Summary
Myometer is a commonly used method for myopia treatment, but it also has some side effects. The use of a myopia table can easily lead to eye fatigue, visual dependence, corneal deformation and decreased adaptability. In order to reduce these side effects, people who use myopia tables should take regular rest, carry out naked eye vision training, and regularly check the health of their eyeballs. Ophthalmologists should also adjust the use of myopia watches according to individual conditions to reduce the impact of side effects.
