Whether the 4.8 visual acuity can be restored depends on the nature of myopia and the treatment method. Usually, a 4.8 visual acuity caused by pseudomyopia can be gradually restored by relieving visual fatigue, etc. If a 4.8 visual acuity is caused by true myopia, it is more difficult to be restored by self-regulation, and it is necessary to control the development of myopia by wearing spectacles, or undergo laser corrective surgery in adulthood. Through the method of dilated optometry, we can find out whether the 4.8 vision is true myopia or pseudomyopia. If the refractive error disappears after pupil dilation, it is usually pseudomyopia, which can be regulated by paying attention to eye hygiene and avoiding eye fatigue, so that the vision can be restored gradually. Vision loss caused by pseudomyopia can be gradually restored through adjustment and correction. If the astigmatism or myopia exceeds 100 diopters after dilated optometry, it is mostly true myopia, which causes irreversible growth of the eye axis, and it is more difficult to recover the vision through traditional correction methods. Individuals with a visual acuity of 4.8 due to true myopia will need to wear eyeglasses to control the trend of vision loss. However, if the individual meets the indications for myopic laser surgery, vision can also be restored through surgical methods. If you have a visual acuity of 4.8, you should go to a specialized eye hospital for a complete examination to clarify the nature of your myopia and have it treated as soon as possible under the guidance of a physician.
