Browline frame
Frames with a heavy upper rim that follows the eyebrows and thin metal or no rims below.
Also: browline, clubmaster style
Browline frames have a bold top rim, usually plastic, over thin metal lower rims or none. The American maker Shuron launched the Ronsir browline in 1947, and by the 1950s browlines were a large share of glasses sold in the United States. They faded in the 1970s and returned from the 1980s. The strong top line echoes the brows, and opticians suggest it for triangle and diamond faces.
