Refined carbohydrates like rice, pasta and white bread also cause rapid spikes in your blood sugar and those rapid blood sugar spikes are also linked to a high risk of AMD or age related macular degeneration.
Processed foods and fast foods are high in trans fats and unhealthy oils, and these trans fats and unhealthy oils clog arteries and can limit the blood flow to the brain and that blood flow to the brain and eyes is crucial for eye health as well.

To keep your eyes healthy and prevent vision loss or slow vision loss, focus on eating a diet that is rich in leafy greens, fish with omega-3 fatty acids and colorful vegetables including carrots.
Carrots are one of the best vegetables for eye health and vision.
Carrots are rich in beta-carotene and vitamin A, which help your retina function properly and prevent night blindness and reduce your risk of cataracts and macular degeneration.
Although carrots don't improve poor eyesight that is already poor or correct any need for glasses or contact lenses.
The beta carotene in carrots are converted by the body into vitamin A, which is crucial for protecting the surface of your eye or cornea.
Carrots also contain lutein, which also increases the pigment density in your eye and protects your retina.
Carrots improving eyesight is partly a myth that originated from WWII propaganda, but carrots prevent vision deterioration instead of reversing it.
Raw carrots offer health benefits for your eyes and overall health, although cooking carrots also increases your body's absorption of the beta carotene.
Other orange vegetables like pumpkin and sweet potatoes also provide similar eye health benefits.
