This may be a bit off topic but it is related to insurance and so far no one has been able to give me a straight answer!
My father-in-law went for his eye test at a local branch of Boots. He doesn't have much money, so he has always got the prescription and then bought off the peg glasses. This time the optician told him that because he needs the glasses for driving he has to buy prescription lenses from them and to use off the peg lenses is illegal! Now I have never heard of this rule and cannot find any mention of it on official websites. I am concerned because Boots have forced him into ordering glasses that are at least four times what he would usually pay, and to be honest he is panicking because he can't really afford them!
Can any body help with the actual legal requirements please.
