So sorry to hear about your husbands eye sight Barbara...I would do what Carol has suggested about having a look at your husband's notes at least then you'll know if the other optician new about it. It won't help I know but it could have if he had spotted it in time. It's really annoying if he hadn't spotted it. I'm sorry I don't know much about it but sending you hugs and hoping somehow he can find a way  to make life easier as Carol's mum has done.

Love Sheila xx
