IMO, the weird part is taking your glasses off in the first place, especially when you apparently need them for desk work. It's not like they're coming in from outside or were taking a shower, they were clearly already sitting at the desk in working position.
Some people don't wear their glasses full-time. Could be they only usually use it for computer work and forgot to put them on until some eye strain set in.
I can't conceive of seeing... anything without my glasses, but some do.
