The decision to prescribe glasses for myopia requires great attention. Teenagers and children often experience pseudomyopia due to excessive reading or writing, which can cause regulatory tension or spasms. Of course, people with pseudomyopia are absolutely not allowed to wear myopia glasses but should receive timely treatment and strengthened guidance on visual hygiene to restore normal vision. However, due to the decrease in vision caused by true myopia, which affects learning and workers, whether it is mild, moderate, or high, optometry and glasses should be performed.

Glasses not only restore normal vision or improve vision, but also restore balance or near balance in adjustment and convergence, eliminate muscular eye fatigue, and are beneficial for learning and work. As for myopia glasses, do you often wear them well? Do you only wear it when looking far? Is it better to wear partially corrected glasses? How about wearing completely corrected glasses? This depends on the patient's age, occupation, degree of myopia, and habits.

The principle of prescription glasses for myopia is to use concave lenses for correction, excluding emmetropia and hyperopia refractive errors. Among lenses that achieve the normal or satisfactory corrected vision, the weaker one should be used as the prescription for glasses.

Teenagers and children with mild myopia who do not wear glasses still do not affect their learning, so there is no need to rush to wear glasses. Most people with distant vision above 0.8 are pseudomyopia, which is partially true and has a very light degree, so there is no need to wear glasses; But if mild myopia with significant visual impairment is required to wear glasses, the prescription for glasses should be determined by paralyzing the ciliary muscle and optometry. The glasses provided at this time can be worn only when looking far or frequently.
