“Don’t sit too close to the television. You’ll go blind!”… “Turn on the light when you read. If you don’t, you’ll go blind!”… “Don’t cross your eyes, they’ll stay that way and you’ll go blind!” 

These classic bits of eye health wisdom from my dear mother still ring clearly in my ears.

Unfortunately, I sat way too close to the tube, I read in the dark more often than not, and my friends and I probably spent a collective week of our lives looking at each other through crossed eyes… and guess what? My eyes didn’t stay crossed and, believe it or not, I didn’t go blind! 

Fortunately, none of these timeless words of eye health advice shared for years by millions of mothers around the world have turned out to be true.
