Making the grade with mnemonics

$currentPage/@nodeName

By Luke Arundel

Nothing so completely fuses nerdiness, comedy and essential knowledge like the medical mnemonic. They are all over the internet—mostly on websites and pinboards that were created by over-caffeinated students and then left to rot after graduation.

It’s not hard to find optometry mnemonics but it is hard to find good optometry mnemonics. Punny and crude, they just keep getting cornea and cornea.

Inspired by a similar list by Dr Richard Zimbalist on his website OD Career, Optometry Australia has pulled together a few of the best (or least bad) mnemonics for the Student Hub. Though possibly exhausting, this is not an exhaustive list.

Are their others? Send them to editor@optometry.org.au and we will add them to the list.
