I'm having problems with my vision. What could be causing this?

The most common cause of vision problems is a condition called refractive error, which occurs when the light entering your eyes is not properly focused onto the retina. This can result in blurred or double vision, and sometimes even blindness if left untreated. Other potential causes for vision problems include cataracts, glaucoma, macular degeneration, diabetic retinopathy, and other eye diseases. It's important to consult an eye doctor for further evaluation and treatment.
