Keeping your eyes healthy

  • Healthy Vision

    Protecting your vision is more than an investment in your health; it’s an investment in your quality of life. Thankfully, there are steps we can all take to safeguard our sight. Get eye health tips, learn about how vision works, and discover the different types of eye care professionals.

    Need help paying for eye care? Different programs and organizations can help pay for your eye exams, glasses, and operations.

Eye Conditions and Diseases

NEI is your source for information on any eye condition or disease. Discover common symptoms and signs, learn about treatments and prevention options, and get answers to other common questions. 

  • Cataracts

    Cataracts are a common part of aging that leads to vision blurring and trouble with everyday activities. 

  • Glaucoma

    Glaucoma can cause vision loss and blindness, but early treatment can often stop the damage and protect your vision.   

  • Dry Eye

    Are your eyes burning, dry, scratchy, or red? Is your vision blurry? You might have dry eye, a condition that affects millions of Americans each year. 

Rehabilitation and Research

From offering vision rehabilitation resources to cutting-edge clinical trials, we’re doing critical work to understand, prevent, and treat vision loss for all Americans.  

  • Vision Rehabilitation

    Millions of people in the United States are living with a visual impairment. A visual impairment can’t be fixed with glasses, contacts, or other treatment methods. Vision rehabilitation can help people with a vision impairment improve their quality of life and stay independent.

  • Clinical Trials

    Every year, we lead or support dozens of clinical trials and studies focused on eye diseases. Participating in a clinical trial or study can help researchers provide new treatments, learn new information, and find new ways to help. Learn about clinical studies, find opportunities to participate, and explore the impact of past studies.
