These are not the flimsy low quality shields that are plastered all over the internet. Headpiece is molded from high impact polystyrene with an integral ultra clear Lexan polycarbonate lens which is 250 times stronger than glass and 30 times stronger than acrylic.

Can be cleaned with mild soap and water OR EVEN UNDILUTED 70% alcohol, hydrogen peroxide or Vital Oxide without damaging the lens. (See below lens cleaning test)

           Shield fits loupe with light!
