The Eyeglass file format is an example file format developed by digital preservation researcher Ross Spencer to illustrate the process of creating file formats. It is not known to have been put to any actual use in the optical industry, but might be capable of doing so, as it encodes the standard pieces of information which are part of an eyeglass prescription.
Spencer wrote a blog post explaining the choices that went into devising the file format, and created a Github site hosting some Python code and a sample data file.
