A:Answer Hello!
Thank you for your interest in our Alto Frames. At the current time, there are no bi-focal or prescription lenses available for this product. To maintain the warranty of your Bose Frames, lenses can only be replaced with authorised/approved lenses from our collection.
At the current time we are exploring partnerships to allow for prescription/bifocal lenses, but there are no approved channels for this yet. Please keep an eye out on our social channels for future information regarding this!
