Dr. Callahan was professional, knowledgeable, and caring. She listened, explained clearly, and answered all my questions. It was refreshing. She also helped my son, and staff was friendly and kind.

Lowering Your Risk for Age-Related Macular Degeneration
Medical and Health Factors That Influence AMD Risk
Certain medical conditions affect your risk of developing or worsening AMD, even if they seem unrelated to your eyes. Managing your overall health is an important part of protecting your vision. Our eye doctors work alongside your primary care team to give you the most complete picture of your risk.
Uncontrolled high blood pressure and cardiovascular disease are recognized risk factors for AMD. The blood vessels that supply your macula, the central part of your retina responsible for sharp vision, are sensitive to the same circulatory stress that affects your heart. Controlling weight, blood pressure, and cholesterol through your primary care doctor is an important part of reducing AMD risk.
If you have been diagnosed with intermediate AMD, a specific supplement formula called AREDS2 has been shown to reduce the risk of progression to advanced AMD. This formula contains precise doses of lutein, zeaxanthin, vitamin C, vitamin E, zinc, and copper, which were tested in a large clinical trial. These supplements are not recommended for people who have not been diagnosed with intermediate or advanced AMD, and they are not a substitute for a healthy diet.
AMD in its early stages causes no noticeable symptoms. A comprehensive dilated eye exam, where drops are used to widen your pupil so our doctors can see the full retina, is the only reliable way to detect AMD before vision loss begins. Adults 60 and older are generally advised to have this exam every year, and those with risk factors such as a family history of AMD or a history of smoking may benefit from starting earlier.
Between office visits, an Amsler grid is a simple at-home tool that helps you monitor for early changes. If straight lines appear wavy or sections of the grid look blurry or missing, contact our office right away.
How Protective Steps Work Together
No single habit eliminates AMD risk on its own, but combining several protective steps produces results that are greater than any one change alone. Think of each healthy choice as adding another layer of defense for your central vision.
A person who does not smoke, eats well, exercises regularly, controls their blood pressure, and wears UV-blocking sunglasses faces a substantially lower AMD risk than someone who addresses only one factor. The benefits build on each other over years and decades, which is why starting earlier matters even if you are not yet in the highest-risk age group.
Omega-3 fatty acids from dietary fish have been linked to a reduced risk of AMD in observational research. Importantly, fish oil supplements did not show the same protective benefit in the large AREDS2 clinical trial. Whole food sources such as salmon, sardines, and mackerel remain the most evidence-supported way to get these beneficial fats for eye health.
Obesity is a recognized risk factor for AMD. Excess body weight increases inflammation and places strain on the cardiovascular system, both of which can affect the health of your retina over time. A balanced diet and regular exercise support healthy weight management and also reduce risk for heart disease and diabetes, conditions that can further affect eye health.
Frequently Asked Questions
Here are answers to questions our patients commonly ask about AMD risk reduction and what to do next.
Your risk begins to decrease after you quit, and research suggests that people who stopped smoking about 20 years ago have a similar AMD risk to lifelong non-smokers. That does not mean it is too late to quit at any age. Every year without smoking reduces your cumulative exposure and gives your body more time to recover from the damage.
Lifestyle changes can meaningfully reduce your risk or slow progression, but they cannot eliminate the possibility of AMD entirely. Age and genetics are factors that cannot be changed. What these habits do is shift the odds in your favor and, if AMD does develop, potentially delay or slow the more damaging stages. That said, the protective impact is real and worth the effort.
AREDS2 supplements are specifically studied and recommended for people with intermediate or advanced AMD in one eye. They are not shown to prevent AMD in healthy eyes or in people with only early-stage AMD. If you are in good eye health, focusing on a nutrient-rich diet is a better strategy than adding high-dose supplements. Our team can help you decide what is right for your specific situation at your next exam.
Yes, having a first-degree relative with AMD raises your personal risk significantly. This family history does not guarantee you will develop AMD, but it is an important detail for our doctors to know. Sharing this information at your exam allows us to recommend an appropriate screening schedule and personalized risk-reduction guidance tailored to you.
Adults aged 60 and older are generally advised to have a comprehensive dilated eye exam every year. If you have additional risk factors such as a family history of AMD, a history of smoking, or cardiovascular disease, our team may recommend more frequent visits. More regular monitoring helps us catch any early signs of change before vision is affected.
UV-protective sunglasses help limit cumulative sun damage to the retina and lens over many years. While no study has proven that a specific pair of sunglasses prevents AMD on its own, both the American Academy of Ophthalmology and the National Eye Institute recommend UV protection as part of overall eye health maintenance. Choosing sunglasses labeled UV400 or 99 to 100 percent UVA/UVB is the best standard to look for.
