[Northern Xinjiang Science Popularization] How to wear defocus glasses?

Among the many myopia prevention and control methods, defocus glasses that can delay the development of myopia are becoming more and more popular. So, what are the precautions for wearing defocus glasses?

First of all, defocused glasses should be worn all day except when sleeping and bathing to achieve a more ideal control effect. In daily life, pay attention to taking off and putting on glasses with both hands to avoid the problem of the frame shifting downward. If it is the first time for a child to wear defocused glasses, he will feel tired or blurry when looking at close objects for a short period of time. This is normal. Secondly, wearing defocused glasses requires equal defocused stimulation for both eyes. Be sure to avoid tilting your head to read and write, and lying on your side to read, which will cause anisometropia, which has a great impact on vision. Rinse the defocused glasses with clean water. If they are particularly dirty, you can use a little glasses detergent to make foam, wash gently, and absorb the moisture with a soft paper towel.

Finally, defocus glasses are not a panacea. They can indeed control the rapid growth of the eye axis, but they cannot stop the growth of the eye axis. If the wrong eye use continues, and the factors that stimulate the growth of the eye axis are stronger than the control power of defocus glasses, myopia will still increase. Sufficient outdoor and visual function training can reduce the stimulating factors that form myopia and achieve ideal prevention and control effects.
