Sublime OpticsSublime Optics Replacement Lenses for BOSE Alto S/M BMD0008 or BMD0007 frame SM

Quality is good

These are nowhere near the quality of the genuine Bose lenses. They're pushing a boundary stating "mirrored" finish. They'll do as a temporary replacement but I think I'll stick to the original ones, you definitely get what you pay for.But, they fit the frame fine no issues with the size just the quality for me.

Doesn't fit S/M

Only source I know of for M

speedy delivery and although a tiny bit fiddly to fit they do fit - am very pleased with purchase - would recommend as bose themselves do not make clear lenses - these are ideal for winter or when indoors as you can still use the glasses for calls without looking like an idiot :-)

They fit perfectly into my SM Bose frames! Got them way earlier than shipping said they would take! The lenses come with nice packaging to help keep them safe and they also come with a microfiber bag to put the glasses in. They were super easy to install! There were no instructions on how to install them but in two clicks I found a video on how to do it through Bose!
