Normal vision in the left eye and 75 degrees in the right eye may be caused by myopia, astigmatism, farsightedness, etc. If it is true myopia with naked eye vision lower than 0.6, astigmatism, farsightedness and the need to wear glasses, it is recommended to go to the hospital for further checkups, and according to the doctor’s advice to decide whether you need to wear glasses or not. 1. Myopia: myopia is divided into true myopia and pseudomyopia, if it is true myopia, vision examination, found that the naked eye visual acuity of 0.8 or more does not affect the life or learning, you can not wear glasses, but if the naked eye visual acuity is less than 0.6 to wear glasses as soon as possible, if it is pseudomyopia, can be corrected by eye exercises, keep sitting upright vision can be restored. 2. Astigmatism: Astigmatism is a refractive state caused by the inconsistency of the refractive power of the refractive system of the eye in different meridians. Parallel rays of light passing through the refractive system of an astigmatic eye are unable to form a focal point in the macula of the retina, which leads to a decrease in visual acuity and the need to wear eyeglasses. 3. Hyperopia: The light rays emitted by an object will form a focal point in the eye after refraction by the refractive media in the eye. If the focal point falls to the retina, resulting in the retina not being able to show a clear image, it is hyperopia, which will cause vision loss and require glasses. It is recommended that patients with normal vision in the left eye and 75 degrees in the right eye should go to the eye hospital for examination in time, and according to the doctor’s advice to decide whether they need to wear glasses or not, and they can eat more carrots, cabbage, spinach and other vegetables, which are good for the health of the eyes.
