We polish the edge of every Poly lens since this has reduced dramatically the occurence of cracked lenses. I learned this from a post on this Forum.
But when edging a "V" bevel on a poly polarized lenses, if the groove of the frame is not deep enought (very deep), there is a transparent area betwen the dark front surface of the lens and the frame and some patients do not like that.
Any idea of how to avoid this?
