Some eye conditions, like diabetic retinopathy and certain corneal diseases, can be treated so that vision is restored or maintained.

Learn More About Your Vision Loss
You can order written or taped materials on vision loss through state agencies and non-profit organizations. You may also find it helpful to discuss vision loss with your doctor, as well as other people who have lost vision.
Seek Therapeutic Counseling for Vision Loss
While vision loss can occur at any age, it occurs most often among mature adults. Like any other major life event, vision loss can bring feelings of loneliness, helplessness, anxiety, and depression. Doctors, state agencies, and non-profit organizations offer counseling services for those with vision loss and can provide referrals to other professionals based on individual needs.
Grieving the Loss of Vision
The loss of vision is initially devastating. Understanding the process of grief associated with vision loss can help you and your loved ones cope with these physiological and emotional challenges.
Explore Adjustment Classes and Devices for Vision Loss
Tasks as simple as dressing in the morning or as complex as cooking a meal become new challenges after vision loss. In adjustment classes, individuals can learn new or alternative techniques to help maintain independence. While building mobility and motor skills, these classes and aids also teach the patience and confidence required to live with low vision on a daily basis.
