That wasn't meant to happen!!!

While working yesterday my glasses were needing a bit of a clean. I took then off and started to clean them on my top as usual except this happened. I should be ok as far as getting headaches (i hope) as i have been without my specs before but that was 20 years ago and i'm a old man now lol. Got a appointment with the optician for a week on sunday so not too long without them and i needed new ones anyway. Please forgive of if my blips are a bit out of focus over the next wee while but without my glasses i won't be able to tell until on pc when too late! I have had them for 6yrs which is a long time in specs time.
