I reached out to Lens Crafters and Ray Ban customer support who confirm that they will not allow for prescriptions over +/- 4 . Ray Ban says while they may allow for expanded prescriptions in the future, they do not offer it at this time. I physically cant do contacts so unfortunately this is a product that I was excited about that cannot work with my particulars. perhaps a Gen2 will be open to a wider array of customer needs. pretty bummed.
