One eye is nearsighted and the other eye is not, indicating that the refractive state of both eyes is not equal, a phenomenon known as refractive aberration, which can easily lead to visual fatigue and a lack of three-dimensional sense. This phenomenon is called refractive aberration and is easily treated with glasses, which can be used for one eye with nearsighted glasses and the other with flat lenses. When the degree of myopia exceeds 300 degrees, wearing frame glasses may cause dizziness and discomfort, then you can wear contact lenses for nearsighted eyes. If you do not want to wear frames or contact lenses, the myopic eye can be treated with excimer laser or femtosecond laser surgery.
