What is already known about this subject:

  • Myopia ('short-sightedness') is becoming increasingly common in Australia and worldwide.
  • Vitamin D deficiency, usually due to insufficient sun exposure, is also becoming increasingly common.
  • Spending more time outdoors decreases the risk of myopia, though it is not yet known if this is due to increased vitamin D levels.

What this study adds

  • Vitamin D levels in blood samples and eye examination data from the Raine Study participants at 20 years of age found that young adults with myopia had lower vitamin D levels.
  • Vitamin D deficiency was also associated with a higher risk of myopia.
  • Further research is warranted to investigate whether vitamin D is able to directly influence eye health or if it is a marker for eye sun exposure.
