Vision 0.2 Is it serious?

Under normal circumstances, uncorrected vision should reach 1.0. At this stage, vision 0.2 indicates severe vision decline. Many diseases of ophthalmology can lead to vision decline. It is necessary to go to the hospital for eye examination to confirm the specific reasons. Different reasons lead to vision decline. The treatment methods are different. For example, vision decline due to myopia, hyperopia, astigmatism and other reasons can be treated by wearing glasses or laser surgery. For vision loss caused by cataract, surgery is needed to replace the opaque lens inside the eye with a transparent intraocular lens to restore vision. For vision loss caused by retinal detachment, surgery is needed as soon as possible to reposition the retina to restore vision. If surgery is not timely, irreversible damage to retinal function will occur.
