A fantastic eye glass by Schweizer. The housing is aluminum (anodized), it has a biconvex silicate glass lens with a plano-convex front lens and an air-vent hole.

The lens is scratch-resistant and produces a very sharp and extremely high contrast image. Schweizer uses a UV absorbent optical crown as used with prescription lenses (refractive index n=1.52).
