Everyone’s vision matters! 

As always, Grafix is committed to our customers’ safety, and to innovating on your behalf. With the upcoming eclipses, we knew that making filters for everyone’s safe viewing was critical – because when it comes to viewing a solar eclipse, maintaining eye safety discipline is crucial. That’s why we spent the last couple of years bringing this special grade of Eye-Safe Black Duralar polyester film to market.

We’ve put our decades of polymer film expertise to work and created a product that’s all about your safety. Eye-Safe Duralar has been carefully designed and tested to meet the ISO Specification 12312-2:2015 for transmittance, the international standard for direct solar observation safety. You can rest assured that with proper use of our film, your eyes are protected while you enjoy the awe-inspiring spectacle of a solar eclipse.
