I've been assuming that you wear prescription eyewear, but I now suspect not.

No? It's time to go visit an optometrist, they take care of fitting every type of face and will know what safety frames can be had. The selection my not be great, but hey, they are safety glasses, you won't be wearing them where anybody will care. After that it's just a matter of having a zero power safety lens cut to fit the frames.

It will be a LOT more expensive that anything purchased over the counter, but you will get what you need.

Who knows, the optometrist may even know where the get something OTC.
