The Dilemma: How Can You Maintain Your Independence After Vision Loss?
There is no single “road map” that will help you regain self-sufficiency, improve your quality of life, or function independently, but there are many options available to help you find the right service for you.
Step 1: Start with your eye care professional
An ophthalmologist treats eye diseases, prescribes medications, and performs all types of surgery, whereas optometrists prescribe corrective glasses and contact lenses and perform certain surgical procedures.
Step 2: Have a low vision examination
Low vision optical devices, which are different from regular glasses and magnifiers, use lenses to magnify images so that objects or print appear larger to the eye. Adaptive daily living equipment includes devices designed to make everyday tasks easier for people with reduced or no vision.
Step 3: Investigate additional vision rehabilitation services
Vision rehabilitation services can help you function safely and independently in a number of key areas of daily life.
