Carrots support healthy vision but do not give superhuman night sight. They provide vitamin A, which the retina needs to work properly in low light.
How carrots support vision
Carrots are rich in beta-carotene, which the body converts into vitamin A. Lack of vitamin A can cause night blindness, so a balanced diet including carrots helps prevent this deficiency.
- Vitamin A is essential for the light-sensitive cells in the retina
- Severe lack of vitamin A can lead to dry, uncomfortable eyes
- Carrots work best as part of an overall healthy diet
- Eating more than you need will not sharpen night vision further
When poor night vision needs checking
If night vision is getting worse despite a good diet, an eye examination is important. Glasses, cataracts, retinal disease, or other health problems may be involved.
- Book a check-up if driving at night feels less safe or more stressful
- Mention any difficulty adapting from bright to dim light
- Tell the clinician about medications or general health conditions
- Do not rely on diet alone if vision is noticeably changing
