> **Summary:** Protecting eye health comes down to a balanced diet, enough sleep, limited screen time and regular eye examinations. Most eye conditions can be kept from causing permanent sight loss if they are noticed early.

## Quick Facts
- **Sleep:** Six to eight hours a day; around seven hours on average for adults
- **Screen rule:** Look at something distant for twenty seconds every twenty minutes
- **Eye exams (healthy adults):** Every 2 years up to forty, once a year after forty
- **Higher-risk groups:** Every six or every three months if the doctor advises (glasses or lens wearers, glaucoma)

## Foods Good for Eye Health
Eat them regularly and in measured portions.
- **Fish** (salmon, tuna, mackerel, sardines, trout): omega 3 acids.
- **Carrots and orange foods** (sweet potato, mango, apricot, melon): vitamin A, help the eyes adapt to darkness.
- **Broccoli:** rich in vitamins A, C and E.
- **Eggs:** high in protein; contain lutein, zeaxanthin and zinc, which support the health of the macula.
- **Citrus fruits** (orange, grapefruit): vitamin C, protection against UV damage.
- Spinach and walnuts are also listed as eye-friendly.

## Foods That Harm Eye Health in Excess
- **White bread and pasta:** linked with conditions such as macular degeneration, especially with age.
- **Fried food with trans fats:** leads to high cholesterol and diabetes, which harm the eyes as they advance.
- **Processed meats** (sausage, salami, cured meat): high sodium can raise the risk of cataract and macular degeneration.
- Foods high in salt.

## Sleep
The eyes rest properly only during sleep. Poor or irregular sleep causes dryness, itching, redness, light sensitivity and eye strain. Aim for six to eight hours a day; around seven hours is generally enough for adults.

## Screen Use
Limit device time, especially for children at a developmental age, to reduce the risk of refractive errors and needing glasses. With heavy screen work, look into the distance for twenty seconds every twenty minutes, and stay away from screens after working hours as far as possible.

## Eye Examinations
Every 2 years up to forty and once a year after forty; more often if glaucoma runs in the family. People who wear glasses or lenses, or have serious conditions such as glaucoma, may need check-ups every six or every three months, as their doctor recommends.
