| Vitamin A | Prevent night blindness and protect the cornea | 900μg for men, 700μg for women |
| Lutein | Filters blue light to reduce risk of macular degeneration | 6-10mg |
| Zeaxanthin | Synergizes with lutein to protect retina | 2mg |
| Omega-3 fatty acids | Relieve dry eye syndrome and promote retinal development | 250-500mg (DHA+EPA) |
2. Ranking of eye-protecting foods
According to recent hot search data and nutritional recommendations, the following foods are particularly beneficial to eye health:
| food name | core nutrients | Eye protection effect |

4. Common misunderstandings about eye-protecting diet
According to the recent popular science content of ophthalmologists, special attention should be paid to:
1.Animal liver should not be consumed in excess: Although rich in vitamin A, consuming more than 100g per week may cause vitamin A poisoning.
2.Supplements are not a replacement for food: The absorption rate of lutein supplements is only 1/3 of food, so it is recommended to give priority to dietary supplements.
3.Cooking methods affect results: The absorption rate of β-carotene is 6 times higher when carrots are fried than when eaten raw.
5. Eye protection recommendations for special groups
| crowd | Key needs | Exclusive food recommendations |
