Four Eyes

Last week, I accidentally broke my boyfriend's glasses. When we went to buy new ones I decided to get a check-up and buy some new glasses, too.

Weirdly my prescription had changed from just over a year ago; my eyes have actually got better! Right eye changed from -2.00 to -1.50 and left eye from -2.25 to -0.75!! I was sceptical, but my new glasses feel comfy and I can see fine with them.

Can you guess which are the old ones?
