Myopia

Myopia, or nearsightedness, happens when the eye grows too long, so distant objects look blurry while close ones stay clear. It usually starts in childhood and progresses through the teen years. Vitamin D and omega-3 fatty acids are the supplements most often discussed for it, but little research on their effects has been reviewed here so far. Much of the interest in vitamin D comes from outdoor light exposure, which is linked to slower progression.
