Eye infections may need to be treated with antibiotics. Nearsightedness is usually treated with glasses or contact lenses.
Side effects depend on the treatments used.
All medications have possible side effects. For example, medications used to control diabetes may cause liver damage or allergic reactions . Surgery carries a risk of bleeding, infection, or loss of vision. Contact lenses may irritate the eyes or result in eye infections. Treatment varies according to the cause of the vision change.
