Nutrition plays a crucial role in the performance of different organs, including the eyes. Our eyes are made up of vascular tissue, which means the foods that are unhealthy for the heart are unhealthy for the eyes too. The tiny capillaries in the eyes supply the retina with oxygen and nutrients to keep it healthy. However, foods rich in unhealthy fats can block these blood vessels, compromising eye function and leading to vision problems.

French fries
French fries are often made in the same oil and even reheated multiple times, leading to molecular changes that increase the concentration of harmful fats. A high amount of these fats affects the eyes, heart, and other organs. Also, free radicals in fried foods increase oxidation in the body, which can damage the eyes.

Margarine
Margarine is often advertised as the healthier butter, but it is rich in trans fats— the fat that increases bad cholesterol levels. Increased cholesterol leads to blockages in arteries and other blood vessels, restricting the flow of oxygen, blood, and nutrients. It, in turn, can increase the risk of eye diseases. Healthy alternatives to margarine are coconut oil, avocado oil, and olive oil.

Processed meat
Highly processed meats, like sausages, bacon, and hot dogs, are convenient snacking options. But they are another reason for high cholesterol. The high-fat content harms the eyes, heart, and other vital organs. Regular intake causes plaque build-up in macular vessels, obstructing blood flow to the eyes and increasing the risk of macular degeneration and retina damage.

Frozen meals
Frozen pizzas and other ready-to-eat meals are convenient when in a rush. But that is their only benefit. They have a lot of added preservatives, sugar, and salt, which are detrimental to eye health. Adding a lot of frozen foods to the meal plan can also lead to an increased risk of eye conditions caused by diabetes and lifestyle diseases.

Dressings
Sauces and dressings brought from the store add a touch of taste to the food and make it look attractive. However, high amounts of sugars, salts, and preservatives in these products can harm the eyes. They also have a lot of fat, which, when eaten regularly, can lead to an increased risk of macular degeneration. One can replace store-bought sauces and dressings and use homemade alternatives instead.

Besides avoiding the above-listed foods, doctors recommend eye gels or drops that benefit the eyes. These treatments combat eye dryness and irritation and prevent more serious conditions.
