In the US at least, EssilorLuxottica owns a large portion of the eye glass shops (Target Optical, Lenscrafters, etc) and eyeMed insurance. VSP another eye insurance company has a similar set up where they own their own glasses maker. There's nothing really stopping anyone from buying from discount eye glass companies online, but you have to guess at which frames you'll like based on pictures and reviews instead of instore.
