Carrots are a good source of lutein and beta-carotene, antioxidants that support eye health and help protect against age-related degenerative eye conditions, particularly age-related macular degeneration.
The body converts beta-carotene into vitamin A, a nutrient that assists vision in low-light conditions.
While carrots contribute a modest amount of vitamin A, this nutrient is also present in other foods such as milk, cheese, egg yolks and liver. Therefore, increasing carrot intake will not improve eyesight if dietary vitamin A levels are already sufficient.
The American Academy of Ophthalmology explains that carrots alone do not enhance poor vision. Maintaining eye health relies on a balanced diet, in which carrots play a role, but are not a standalone solution.
Other Health Benefits of Carrots
In addition to their contribution to eye health, carrots offer a range of further nutritional benefits:
Digestive support: Carrots are high in fibre, which aids digestion, prevents constipation and may offer protection against colon cancer.
Blood sugar regulation: Their fibre content slows the absorption of sugar, helping to maintain stable blood sugar levels.
Heart health: Rich in lycopene, an antioxidant, carrots may help lower the risk of heart disease by contributing to healthy blood pressure and cholesterol levels.
Skin protection: Although not a substitute for sunscreen, the antioxidants beta-carotene and lycopene may assist in protecting the skin from sun damage.
Carrots support eye health but are not a cure for poor vision. A combination of healthy habits—such as eating a balanced diet, wearing sunglasses, exercising, avoiding smoking and limiting screen exposure—remains essential for maintaining good vision.
