Wearing glasses and not being able to see what is near may be due to improper prescription of glasses, or it may be due to diseases such as retinal detachment. 1. Improper glasses: Usually myopic or hyperopic patients need reasonable glasses according to their own situation. If farsighted or nearsighted patients do not have a clear degree of their own, arbitrary prescription, resulting in refractive error, there will often be glasses can not see things near the situation. 2. Retinal detachment: usually considered to be due to retinal tears, vitreous pulling and other conditions, and also with aging, high myopia, ophthalmic surgery history, history of serious eye trauma and other factors. Patients often experience floating objects in front of their eyes, blurred vision, flashes of light, and dark shadows. Some patients may also experience difficulty seeing near objects with glasses, decreased visual acuity, and visual field defects. If you can’t see near things with glasses, consult a doctor to find out the cause of the disease, and actively cooperate with the doctor to take reasonable measures, so as to avoid delay or aggravation of the disease.
