Product Description
Schott Glass Technologies has developed a new contrast enhancement glass for spectacle lenses. The new material, called ACE, short for "Amethyst Contrast Enhancer," utilizes rare earth oxides in the glass composition to achieve the unique color enhancing characteristics. Basically, the color enhancement concept works by selectively positioning transmission in the blue, green, and red spectral regions whereby one can improve the color discrimination between different color objects. These are the same colors used to produce a color television picture. They optimize the readability of such displays under high ambient light conditions. ACE Glass utilizes rare earth oxides in its composition to provide the same filtration. This glass is very efficient in filtering sodium flare in addition to providing ultraviolet protection to 390 mm. The 2 ACE glass is becoming a preferable choice of lamp workers. It is very comfortable for viewing under high ambient light conditions such as when working with glowing heat sources for a duration of time. Also, although it has a relatively low luminous transmission of 38%, it is not recommended for sun protection use unless UV filtering coatings are applied.

I work in a laboratory, and part of my duties include working pyrex glass. The sodium flare-off is bright enough that it is often hard to see the workpiece. I've been using didymium eyeware for many years. When my previous cheapie plastic pair finally failed, I went looking for a replacement.The ACE glass spectacles I bought were not the pink didymium I was used to, they tend towards more of a pale cobalt shade. However, in practice, they are most excellent for removing the sodium line from the working flame. I found them to produce high contrast, minimum darkening, and better color rendition than the pink shades I was used to. They are comfortable and do not get heavy on your face with extended use.The only downside to these glasses is that they are a bit pricey. Time will tell, if they hold up nearly as long as my cheap plastic lenses, they will have been well worth the price.If you need a pair, these are good and cheap enough.
