Myopia of 300 degrees may usually be 4.1 or even below 4.1. Often identifying the maximum visual scale of the vision chart may feel like a struggle. Myopia 300 degrees belongs to the dividing line between low myopia and moderate myopia, which is not a very low degree of myopia and needs to be corrected with glasses, especially for children who are attending school. If children do not wear glasses, it will definitely affect their studies, they will not be able to see the blackboard, and it will also accelerate the progress of myopia. In addition to glasses, adults can also choose surgery to correct their needs. Laser surgery or crystal implant surgery can meet the degree of correction, and the recovery of vision after surgery is also good.
