Negative Diopter Lenses?

Anyone know of a source for negative diopter lenses for the front sight? I am looking for about -.25D. Anschutz has what appear to be positive .3 and .5D lenses -- are these really negative?
Best,
Joe

I'd suggest you do a google search on diopter and see what decimal numbers refer to, I don't know the maths behind diopter calculations.

anschutz makes a thingy for the rear sight, it screws in like an iris, that goes from -4.5 to +4.5. no idea where you might get it. the front sight lenses you are talking about are positive.
