Is one pair of sunglasses just a back-up?
no
one set (normally and sunglasses) are from 2011
another set is from 2013
and this year i didn't like the style they had to i had specsavers put new lens on the pair i well use for driving.
I found that this year the style were mainly big/nerdy/round looking, and not the thinner ones that i like in the pic.
i found some online companys that can put new len on your current glasses and the extra option that you get from specsaver but are cheaper and offer some type of warranty, whereas with specsaver it cost more and there is no warranty plus they will not be responsible for any damaged done, whereas the online companys will pay you if they damage your glasses
