I recently signed up for vision insurance with my employer in hopes to get some blue light glasses. I went to the eyeglass website my insurance is affiliated with and I want to use my frame allowance but I can’t spend it unless I get either single vision or progressive lenses. Can I just order one of these without a prescription? Will it be as if I ordered non prescription lenses? My whole reason for getting vision is for getting blue light glasses because I am on screens all day.
