Although slightly off-topic, if you think you need new specs, then this will gladden your heart ...
At the age of 6 our daughter had perfectly good vision (I knew that because two days previously she'd had her eyes tested). T'was the school summer holidays, so, being a nice day we took her to the beach and, later went for a walk along the prom.
Because Daddy stopped every few yards to scan the horizon through his binoculars, he was soon left well behind, until I couldn't actually see him at all - with or without me specs - but the 6 year old could and having the younger, sharper eyes I was daft enough to believe her. So, we turned around, retraced our steps and walked for what must have been well over žmile, until it finally became obvious that 'Daddy' was none other than one of those giant plastic ice-cream cones!
From this we learnt a couple of valuable lessons: (1) be very careful which Optician you pick for your child and, (2) if you
do happen to have grey hair by the time you're 38, do not wear beige trousers and/or stand still for very long - you may find 6 year-olds mistake you for an ice-cream.
