The surface finish is a flat and sort of opaque and I'm wondering if the plastic has to be polished in order for this to work... My gigaware webcam can only see them if I hold the led about 6 inches in front of the camera.. it shows up as a white circle. (Using floppy disk over lense)

I'm just wondering if polishing is needed for some reason.. I know they sell diffusers for leds that increase the viewing angle and they're sort of a frosted finish.
