Why We Need Glasses

This has been a mystery for a long time. We have blamed genetics and environmental factors and other factors for many years. I listened to a fascinating podcast about this topic. The resercher found that being born in the summer may be linked to becoming nearsighted but can’t tell us why there is an association between summer birth month and being nearsighted.

I think that you’ll find this podcast interesting, and its not very long.

Here’s a link to the podcast.
