It's necessary to wear glasses. Some people afraid that after wearing galsses, myopia will be heavier. However, it's not true. the use of glasses or contact lenses does not affect its progression. In fact, because of using eyes frequently, muscle of eyes is easy to get tired. After wearing glasses things become clearer and eyes get relax. To some degree, glasses can prevent myopia. Generally speaking, myopia of -3.00 diopters or less called low myopia. So you can try the following methods, including wearing galsses, eye drops, and participating in more outdoor activities. I was nearsighted with -2.50 diopters, now i am nearsighted with -1.00 after graduation. So i believe you can have perfect vision again.
