Cheap glasses

In the office today for a meeting and when everyone nipped out for lunch I took the opportunity to take some shots of the desk space. Over Xmas, I lost my glasses and rather than replace them at a cost of £200+, I am simply making do with a pair of £5 plastic reading glasses.

They do the job perfectly and don't even break if you sit on them. I know this because I did it this morning whilst getting dressed. They are also more phoeogenic than the ones I lost so that is an added bonus.

Reckon my next eye test is due this year. Question is do I stump up for a proper pair of glasses or stick with the cheapies?
