Some foods are noted to be “great for vision” – for example, carrots, mangos, etc.
What does “great for vision” even mean? I wear glasses and am under the assumption that my poor eyesight isn’t going to magically slightly improve by downing foods rich in certain vitamins and minerals.

Carrots being good for your eyesight was part of a [WWII misinformation campaign.](https://www.healthline.com/nutrition/are-carrots-good-for-your-eyes#carrots-and-eye-health) When the British first started using radar to shoot down enemy planes, they didn’t want the technology to be widely known, so they said their pilots simply had better night vision from eating carrots.
