Children with hyperopia experience a decrease in visual acuity after wearing spectacles, which is commonly caused by physiological phenomena, inappropriate prescription of spectacles or incorrect wearing of spectacles, and so on. If there is a decrease in naked eye vision, it is because after wearing glasses, children’s eyes are relatively in a relaxed state, and when the glasses are removed to check the vision, it is difficult for the eyes to adapt to the tense adjustment state before wearing glasses in a short period of time, which is manifested as a decrease in naked eye vision, which is a normal phenomenon. If children with hyperopia experience a decrease in corrected visual acuity after wearing eyeglasses, it is often caused by wearing eyeglasses with inappropriate prescription or not wearing them correctly, which may aggravate amblyopia. It is recommended that children go to the hospital for examination and clarification of the specific causes.
