The Optitune Adjustable Smart Glasses are glasses with adjustable focus, so the wearer can tune the lenses to their own eyesight without a prescription. That makes them useful as a spare pair, for reading at different distances, or for people whose vision varies. They are a niche product: they lack the audio, camera and app features of smart glasses from bigger brands, and their appeal rests on the adjustable lenses rather than on connected features.
