So what you are saying is you have spent 130 quid on glasses that might not be fit for the purpose you bought them (to wear them all the time).
Your right you better hide that receipt!
LOL! As long as they fit they will do the business, certainly during the summer months. Not too bothered about the winter, but it would be a nice bonus if they were ok. I did read a review somewhere that suggested that they should be fine at night.
P.S. They were just over £100 not £130!
