Diffraction Glasses Coming Home Today.

Dear Parents,

Just a quick heads up to let you know that your kids are coming home today with diffraction glasses. They LOVE them.

You can learn more about how they work here:


The reason I wanted you to know about the glasses is to be sure that they don’t stare at the sun — or other insanely bright lights — with their glasses on! The glasses do cool things with white light, but they are not protective — so if your kids look straight into an incredibly bright light with the glasses on, they will feel pain.

As an aside, take the glasses with you when you go look at Christmas lights in the neighborhood. You’ll dig them. And your kid SHOULD be able to explain the science behind the glasses to you all at the same time.

Hope this helps,

Bill Ferriter
