When thinking about maintaining good eye health, it’s easy to focus solely on regular eye exams or wearing the right prescription glasses. But did you know that your diet plays a major role in protecting your vision? At ERC Optometry, we believe in a holistic approach to eye care, which includes understanding how what you eat can impact your eyes.
While plenty of foods are celebrated for their eye health benefits—like leafy greens, fish rich in omega-3s, and citrus fruits—it’s just as important to know which foods may harm your vision over time. Some of the worst foods for eye health include sugary foods and drinks, processed meats and foods high in sodium or trans fats, fried foods, refined carbs, and alcohol. You might want to think twice before indulging in them regularly.
Sugary Foods & Sugary Drinks
Sugar doesn’t just affect your waistline; it can also harm your eyes. High amounts of added sugar in foods and beverages—think soda, candy, pastries, and some cereals—can contribute to blood sugar spikes. Over time, these fluctuations may lead to a condition called diabetic retinopathy, where high blood sugar damages the blood vessels in your retina.
This condition is one of the leading causes of blindness in adults and can usually be prevented through balanced blood sugar management and proper nutrition. Opting for fresh fruit or low-sugar alternatives can help keep your sweet tooth in check without risking your eye health.
Processed Meats & High-Sodium Foods
Processed meats like hot dogs, bacon, and deli meats aren’t just high in saturated fat—they’re also packed with sodium. A diet too high in salt can raise blood pressure, which in turn may lead to hypertensive retinopathy. This condition causes damage to the blood vessels in the eyes and can lead to vision complications.
Sodium is also a common ingredient in canned soups, frozen meals, and salty snacks. If you’re reaching for these items often, consider switching to low-sodium versions or preparing fresh meals at home. Keeping your salt intake in check is not only good for your eyes but can also support your overall cardiovascular health.
Foods High in Trans Fats
Trans fats are a type of artificial fat found in some packaged goods, margarine, and fast food. These fats are not only bad for your heart—they can negatively affect your vision too. Some studies suggest that diets high in trans fats may interfere with the absorption of omega-3 fatty acids, which are essential for eye health. Omega-3s help maintain the health of your retina and reduce the risk of dry eye syndrome.
Try to steer clear of hydrogenated oils and instead choose heart-healthy fats like olive oil or avocado oil as part of an eye-friendly diet. Checking ingredient labels can also help you avoid hidden sources of trans fats in your food.
Fried Foods
We all know fried foods—like French fries, fried chicken, and onion rings—taste great, but they can come at a cost to your body, including your eyes. Fried foods are often cooked in unhealthy oils that produce free radicals. These free radicals can damage cells throughout the body, including the delicate tissues in your eyes.
Free radicals are also known to accelerate a natural process called oxidative stress, which has been linked to conditions like macular degeneration and cataracts. Reducing your intake of fried foods and focusing on grilled, baked, or steamed options can make a big difference for your long-term eye health.
Refined Carbohydrates
Refined carbs—found in white bread, pasta, instant rice, and other processed grains—can also negatively impact your eyes, especially if consumed regularly. Foods high on the glycaemic index (GI) can cause quick spikes in blood sugar, which over time may contribute to diabetes and vision issues.
A diet based on whole grains, legumes, and vegetables with low GI values provides a steadier source of energy while supporting better eye health. Swapping refined carbs for options like quinoa or whole-grain bread is a small change with big benefits.
Alcohol
Occasionally enjoying a glass of wine or beer is fine for most people, but heavy or frequent alcohol consumption can take a toll on your eyes. Alcohol dehydrates your body, including the eyes—a common culprit behind uncomfortable symptoms like dry eyes or redness.
Chronic drinking can also lead to a deficiency in essential vitamins and nutrients, including vitamin A, which is crucial for maintaining clear, healthy vision. Excessive alcohol use has even been linked to an increased risk of optic neuropathy, a condition that damages the optic nerve and can cause vision changes.
How to Make Eye-Healthy Choices
A diet built around whole, nutrient-dense foods can do wonders for your eyes. Incorporating plenty of fruits, vegetables, lean proteins, and healthy fats ensures your eyes get the vitamins, minerals, and antioxidants they need to function at their best. Foods like spinach, carrots, salmon, and walnuts are excellent choices to include in your daily meals.
Drinking plenty of water and limiting dehydrating beverages like alcohol or caffeine can also help keep your eyes lubricated and comfortable. And don’t forget to enjoy your meals in moderation—a balanced approach to eating is key to supporting both your vision and your overall health.
