The Solar Eclipse was a once in a lifetime experience and although its over, the buzz is still alive. Have you been wondering what made those glasses solar safe?
In other words, some of you may be thinking how did a flimsy pair of plastic sunglasses that seem to closely resemble the disposable 3D glasses you’d get a movie theater protect people from blindness?
It’s all in the Polymer. The glasses are made from a black polymer (a resin infused with carbon particles). This composition blocks almost all visible light and all of the ultraviolet (UV) radiation. Standard sunglasses do a pretty good job with UV radiation but only filters less than 20 percent of visible light.
That’s right, we have got to thank plastic for this one.
