What context is this used in? Is it general slang, optometrists' jargon? (If you don't think it's attested at all, feel free to move this to RFV.) - -sche (discuss) 03:29, 12 February 2014 (UTC) Moved from the Tea Room, since no-one vouched for it being used in a particular context/jargon, and I can't find it in general (or specific) usage. - -sche (discuss) 22:19, 15 February 2014 (UTC)


 * This seems to be a mistake for O2 or O2. That is, it should be the letter, not the numeral.  It is an alternative to the medical abbreviation OU (oculus uterque or, in some sources oculo utro) and is coordinate with OD (oculus dexter) and OS (oculus sinister).  I can find it listed in numerous medical dictionaries/guides, e.g. .  The O2 form seems the more common but the subscript form is also found e.g. .  I did not see any examples of a superscripted form but doubtless it occurs.  Uses in running text are going to be hard to find, and frankly, I doubt they occur.  This seems more like abbreviations that gets written on charts, forms and prescriptions. Spinning Spark  11:53, 24 February 2014 (UTC)
 * Aha, thanks for the information! I've moved the entry to O2, added a tag and removed the  tag, since I presume there are uses out there, even if they're hard to find (given the context they'd be used in and the staggering number of other things O2 means or is a scanno of). - -sche (discuss) 21:57, 24 February 2014 (UTC)
