Didymium Phillips 202 Lense Glasses

Good for soft glass torchworking. Polycarbonate Phillips ace 202 Amethyst Contrast Enhancer Glass didymium lenses filter some infrared and U-V light. Advanced Didymium optics now absorb more yellow sodium flare. Multi-fit bridge and universal fitting with nickel silver temples. Plastic frames and metal reinforced arms. "ACE", short for Amethyst Contrast Enhancer, utilizes rare earth oxides in didymium glass composition to achieve unique color enhancing characteristics. This concept selectively positions transmission in the blue, green and red spectral regions, whereby one can improve color discrimination between different colored objects. ACE glass is very efficient in filtering sodium flare in addition to providing ultraviolet protection to 390NM. It makes it very comfortable to view under high ambient light when working with glowing hot glass over a long period of time. Filters the sodium flare from 575 to 600NM.
