I'd like to be able to see through the clear glass at the top and a reading prescription at the bottom. With these same lenses, can I get transitions lenses? and how much? Also, can I get this in the progressive style with no lines? How much extra? My frame is a Bvulgari frame with Swarovski crystals. Are these safe to send? I would insure them, but what steps do you take to ensure they arrive back to me? Thanks
