Lowering Your Risk for Age-Related Macular Degeneration
Risk Factors You Can Change
Some of the most powerful steps you can take to protect yourself from AMD involve everyday habits. Addressing even a few of these modifiable risk factors can meaningfully reduce your chances of developing the disease or slow its progression.
Smoking doubles your risk of developing AMD, and the effect compounds when combined with genetic risk factors and poor diet. Research has shown that women who carry two high-risk gene variants and smoke are more than four times as likely to develop AMD compared to women without both of those factors. The good news is that quitting now begins to lower your risk, and the benefit grows with every year you remain smoke-free.
A Mediterranean-style eating pattern, which emphasizes leafy greens, fatty fish, fruits, legumes, and nuts, is associated with a meaningfully lower rate of AMD progression. Foods like kale, spinach, salmon, and sardines are especially valuable because they supply lutein, zeaxanthin, and omega-3 fatty acids, all of which support the health of the macula (the central part of the retina responsible for sharp vision). Aiming for fatty fish at least twice a week is a practical starting point.
Regular physical activity is associated with reduced risk of wet AMD, the more advanced and vision-threatening form of the disease. Exercise helps lower blood pressure, supports cardiovascular health, and reduces inflammation throughout the body, including in the eye. You do not need an intense fitness routine to benefit. Brisk walking three times per week is enough to make a difference.
Prolonged unprotected exposure to sunlight is associated with increased AMD risk. Wearing sunglasses that block 99 to 100 percent of UVA and UVB rays every time you are outdoors helps reduce that cumulative damage. Look for lenses labeled UV400 or 99 to 100 percent UVA/UVB protection. Adding a wide-brimmed hat gives your eyes extra coverage and also lowers your risk for cataracts and other sun-related eye conditions.
Medical and Health Factors That Affect AMD Risk
Certain health conditions and medical interventions also play a meaningful role in AMD risk. Partnering with both your eye care provider and your primary care physician helps you manage these factors in a coordinated way.
Uncontrolled high blood pressure and cardiovascular disease are recognized contributors to AMD risk. The circulatory system that keeps your heart healthy also nourishes your retina, so what harms the heart can harm the macula as well. Working with your primary care physician to manage your blood pressure, weight, and cholesterol is an important part of a complete AMD prevention strategy.
AREDS2 supplements are a specific formula developed and studied through large clinical trials. They contain precise doses of lutein, zeaxanthin, vitamin C, vitamin E, zinc, and copper. For people diagnosed with intermediate AMD, these supplements are associated with approximately a 25 percent reduction in the risk of progression to advanced AMD over five years. These supplements are not recommended as a general prevention tool for people with healthy eyes or those with only early-stage AMD. Your eye care provider can tell you whether they are appropriate for your situation.
Early AMD often produces no noticeable symptoms, which means it can quietly progress before you are aware of it. A comprehensive dilated eye exam, in which your provider uses drops to widen your pupils and examine the retina directly, is the most reliable way to detect AMD before vision loss begins. Adults aged 60 and older are generally advised to have this exam annually. If you have a family history of AMD or a history of smoking, your eye care provider may recommend starting earlier or scheduling visits more frequently. Using an Amsler grid at home, a simple printed grid used to check for distortion in your central vision, helps you notice any changes between appointments and report them promptly.
Lifestyle Habits That Work Together
No single change eliminates AMD risk on its own, but multiple protective habits layered together create a stronger defense. Understanding how these habits interact helps you build a sustainable routine that supports your vision over the long term.
Someone who has quit smoking, eats a varied diet rich in vegetables and fish, exercises regularly, controls their blood pressure, and wears UV-blocking sunglasses faces a substantially lower AMD risk than someone who addresses only one of these factors. Each step adds to the others. Small, consistent changes across several areas tend to produce the most meaningful results over time.
Observational studies have linked dietary omega-3 fatty acids from fish to reduced AMD risk, but fish oil supplements have not shown the same benefit in clinical trial data, including the AREDS2 trial. Whole food sources like salmon, sardines, and mackerel are the preferred way to get these nutrients. Aiming for two or more servings of fatty fish per week is a practical and evidence-supported goal.
Obesity is a recognized risk factor for AMD. Carrying excess weight increases low-level inflammation throughout the body and places additional strain on the cardiovascular system, both of which affect the health of the retina. The same habits that support a healthy weight, including balanced eating and regular movement, also lower your risk for heart disease and diabetes, conditions that can further affect your eye health.
Frequently Asked Questions
These are some of the questions our patients most often ask about reducing their AMD risk. The answers below are meant to help you apply this information to your own situation and know when to reach out to your provider.
Risk reduction is gradual but real. Research suggests that people who quit smoking approximately 20 years ago carry a risk comparable to lifelong non-smokers. That said, your risk begins to decrease from the moment you stop, and the benefit compounds the longer you remain smoke-free. There is no point at which quitting is too late to be worthwhile.
No lifestyle strategy can guarantee you will never develop AMD, because age and genetics are factors that cannot be controlled. What you can do is meaningfully lower your likelihood of developing the disease and slow its progression if early signs are already present. Think of these habits as long-term investments in your vision rather than a guaranteed cure.
AREDS2 supplements are specifically studied and recommended for people with intermediate AMD. They are not designed for general eye health maintenance in people without the disease, and taking them without a diagnosis does not provide the same documented benefit. If you are concerned about your risk, a comprehensive eye exam is the right first step before considering any supplementation.
Adults aged 60 and older generally benefit from a comprehensive dilated eye exam once a year. If you have specific risk factors such as a family history of AMD, a history of smoking, or certain cardiovascular conditions, your provider may recommend a more frequent schedule. Routine exams are also an opportunity to catch other age-related conditions like glaucoma and cataracts early.
UV-blocking sunglasses reduce the cumulative sun damage that reaches your retina and lens over a lifetime. While no single study has proven that a specific pair of sunglasses directly prevents AMD, UV protection is broadly recommended by major eye health organizations as part of a responsible eye care routine. For the best coverage, look for sunglasses labeled UV400 or 99 to 100 percent UVA and UVB protection, and wear them consistently rather than only on bright days.
Yes, having a first-degree relative with AMD raises your personal risk by roughly three to four times. This does not mean you will definitely develop the condition, but it does mean earlier and more frequent screening is often appropriate. Let your eye care provider know about any family history so they can tailor your monitoring schedule and give you personalized guidance on the preventive steps most relevant to your situation.
