Laser-X radiation/laser combo protective eyewear system

摘要

A primary lens element fabricated of laser protective glass has proximal and distal faces, a central extent and a peripheral extent. A secondary lens element fabricated of lead oxide has proximal and distal faces, a central extent and a peripheral extent. The secondary lens is operatively coupled to the primary lens forming a lens laminate ground to form a composite lens with a prescription. The composite lens has a central extent of an enlarged thickness and a peripheral extent of a reduced thickness.

主权项

1. A protective lens comprising:
a primary lens element having proximal and distal faces and a central extent and a peripheral extent, the primary lens element being fabricated of laser protective glass; a secondary lens element having proximal and distal faces and a central extent and a peripheral extent, the secondary lens being fabricated of lead oxide glass; the secondary lens being operatively coupled to the primary lens to form a lens laminate; and the lens laminate being ground to form a composite lens with a prescription whereby the composite lens has a central extent of an enlarged thickness and a peripheral extent of a reduced thickness less than the thickness of the central extent.
