Quoted from Maken:Bent plastics help to reduce glare from PF lights on all versions of colordmd.
When I first bought colordmds, I thought I didn't need the bent plastics anymore, and removed them. I was wrong, they are still needed for the reverse glare.
This product works amazingly well for both the LED & LCD (I have both). I removed the bent plastics after installing the glare film.
