Blurred vision is when you cannot see fine details. You may have blurred vision if you are nearsighted or farsighted and you need glasses. Blurred vision may be caused by a corneal abrasion (scratch on the cornea) or a corneal ulcer (open sore). You may have blurred vision if your eye came into contact with a chemical. A foreign body or infection may also cause blurred vision. Medical conditions, such as cataracts, glaucoma, detached retina, and nerve disorders can also cause blurred vision. Blurred vision may also be caused by a concussion or a tumor. If you have diabetes, you may develop diabetic retinopathy. Diabetic retinopathy damages the blood vessels of your retina.
