Night blindness is a common ophthalmological symptom, primarily characterized by poor vision in dim environments. Many factors can cause night blindness, such as advanced glaucoma, retinal pigment degeneration, vitamin A deficiency, etc. It is crucial to seek timely ophthalmic examination at a hospital to diagnose the specific cause of night blindness and then implement targeted treatments. Otherwise, the condition may gradually worsen. For example, night blindness caused by advanced glaucoma can progressively lead to blindness. If night blindness caused by a deficiency in vitamin A is not treated in time, it can also lead to dry eye syndrome, keratomalacia, and other issues. Regarding treatment, night blindness caused by vitamin A deficiency can be treated with oral vitamin A capsules. For night blindness caused by advanced glaucoma, surgical treatment to reduce eye pressure is necessary to halt the progression of the condition.
