Can Eating Carrots Improve Vision? Scientists and Doctors Separate the Facts From Fiction
You have probably been told since childhood that eating carrots will sharpen your vision. With more Americans turning to TikTok wellness trends and supplement aisles for answers about their eye health, the question of whether carrots actually help your eyesight has taken on new urgency. The short answer from experts is yes and no, and the difference matters.
The vegetable does carry real nutritional benefits for your eyes. But the dramatic vision-boosting reputation carrots have carried for decades traces back to a wartime deception, not science.
How Carrots Actually Affect Your Eyes
Carrots are rich in beta-carotene, a plant pigment that your body converts into vitamin A. Also called retinol, vitamin A is essential for good vision, especially in low-light conditions. It helps the light-sensing cells in your eyes, called photoreceptors, function properly by forming the pigments they need to detect light. Without enough vitamin A, seeing in the dark becomes harder.
“Carrots can help maintain your eye health, but they probably won’t cause any noticeable change in your eyesight unless you have a vitamin A deficiency. In that case, consuming them could potentially help repair some vision problems,” according to Warby Parker. “In short, carrots are good for your eyes, but they don’t automatically improve your vision.”
You can also get vitamin A from eggs, dairy and liver. Other orange or yellow plants like sweet potato, cantaloupe, pumpkin and winter squash work the same way carrots do.
Where the Carrots-and-Eyesight Myth Started
The popular belief that carrots dramatically improve vision largely comes from World War II-era British propaganda, per Warby Parker. During the war, the British Royal Air Force developed improved night-fighting success against German bombers and wanted to keep the real reason, new airborne radar technology, a secret.
So British officials spread the story that pilots were eating large quantities of carrots to explain their sharp night vision. The story misled the enemy into thinking diet rather than technology accounted for the success. After the war, the tale stuck and blended with the real science about beta-carotene and vitamin A.
Why Eye Doctors Still Recommend Them
Despite the myth, ophthalmologists across the country agree that carrots earn their place on your plate.
“I don’t think it is a myth,” said Dr. Joseph Chacko, director of neuro-ophthalmology at UAMS. “Carrots and other colorful vegetables have lots of vitamin A which helps the retina to function. We want our patients to eat more vegetables in their diet.”
Duke ophthalmologist Jill Koury says, “Vitamin A in normal, recommended quantities is essential for the maintenance of good vision.”
Milam A. Brantley, M.D., an associate professor of ophthalmology and visual sciences at Vanderbilt University Medical Center in Nashville, told AARP that “the retina needs vitamin A to function.” Adequate vitamin A also helps with night vision and dry eye, both of which worsen with age.
Can Carrots Really Help You See in the Dark?
This is where the myth runs out of road.
“No, carrots do not actually help you see in the dark. This is a common misconception that needs to be addressed,” says Blue Fin Vision. For people with a vitamin A deficiency, eating more carrots may improve overall eye health. But for most people with adequate vitamin A levels, more carrots will not further enhance night vision.
Eye Health Clinic frames it the same way. “While carrots do give us tons of benefits when it comes to their nutrient content, these veggies will not improve our vision alone.” A balanced diet of greens, vegetables and antioxidant-rich foods supports eye health, and so does wearing quality sunglasses.
The American Academy of Ophthalmology recommends a nutritious diet for eye health that includes orange vegetables and fruits with vitamin A, produce rich in vitamin C and vitamin E, leafy greens with lutein and zeaxanthin and beans for zinc.
