a.Polycarbonate in a safety frame
b.A very high-plus lens in a large, rimless drill-mount frame
c.AR coating on a plastic lens
d.Photochromic in a full-rim frame
解析
A very high-plus lens has thick, heavy edges poorly suited to a large rimless drill mount, which stresses the lens at drill points and looks bulky; a smaller full-rim frame is more appropriate.
