摘要
The safety dark glasses (P 1) have a frame (1) containing a single panoramic filter lens shaped to fit over the bridge of the user's nose. The filter glass consists of two separate layers of glass or plastics with an air space between them. The absorption characteristics of each layer are optimized for lasers of different wavelength. Broad temples or side frames with hooked ends (4.1,4.2) are attached to the sides of the lens frame.
