Children with a lazy eye may wear an eye patch on one eye or need surgery to help with weak eye muscles. Therapists who have been trained in vision problems can suggest exercises that may improve some vision problems. Surgery and medication may also be appropriate, as in glaucoma . If vision cannot be improved, training and special devices may help the person adjust to the impairment. It is possible to live a nearly normal lifestyle with most visual impairments.
Many people use eyeglasses or magnifiers so they can still perform certain activities.
To function safely, affected people may, however, need to rely on signals other than sight. For example, some lighted signals at a crosswalk also make beeping sounds to indicate when it is safe to cross the street. People who have severe vision problems or are blind can benefit from special devices and training. A white cane and a guide dog are familiar aids for helping blind people function on their own. Computers are now able to recognize speech and can talk to the person.
