What Kids Eat Might Affect Their Vision

Hong KongWed Aug 20 2025

A recent study looked at over 1,000 children in Hong Kong and found that kids who ate more omega-3 fatty acids had a lower chance of becoming short-sighted.

Key Findings

  • Omega-3s are found in fish and other foods.
  • Kids with the highest omega-3 intake had healthier eye measurements.
  • Kids who ate a lot of saturated fats (like butter and red meat) were more likely to have vision problems.

Eye Measurements and Diet

  • Kids with the lowest omega-3 intake had longer eye measurements, a sign of short-sightedness.
  • The opposite was true for kids who ate a lot of saturated fats.

What the Study Suggests

  • The study does not prove that omega-3s cause better vision.
  • It suggests that omega-3s might help by improving blood flow in the eye.
  • Better blood flow could prevent oxygen deficiency, which can lead to short-sightedness.

The Growing Problem of Short-Sightedness

  • Short-sightedness is becoming more common worldwide.
  • By 2050, it's expected to affect half of the global population.
  • Risk factors include:
  • Too much screen time
  • Not enough outdoor activity
  • Genetics

Diet Matters for Eye Health

This study adds to the growing evidence that diet matters for eye health. It's another reason to encourage kids to eat more fish and less junk food.

questions

    Will we soon see parents bribing their kids with sushi to improve their eyesight?
    How does the study's observational nature impact the conclusions drawn about omega-3 fatty acids and myopia?
    If fish oil can help prevent short-sightedness, does that mean kids should start wearing fish-shaped glasses?
