Children with 75 degrees of myopia are considered pseudomyopia by degrees. Pseudomyopia is myopia caused by excessive contraction and spasm of the ciliary muscle for various reasons, which causes the lens to become convex and changes the refractive power of the eye. In principle, by relaxing the ciliary muscle with adequate rest and physical therapy, the degree of pseudomyopia can be reduced or even restored to the normal eye. The corresponding treatment measures are as follows: First, ensure two hours of outdoor activities every day. Second, for every hour of reading or writing, rest your eyes for 15-20 minutes. Third, pay attention to balanced nutrition, especially adequate vitamin supplementation. Fourth, you can take appropriate physical therapy measures, such as insisting on doing eye exercises every day, along with the use of eye drops to relieve ciliary muscle spasm.
