My DD age 14 needs new glasses.
She likes some with really thick frames which according to the optician are now the 'fashion' but which DH and I really don't think suit her colouring or face (all you see are the glasses). Also they remind me of the old 'NHS glasses' of the 70s.
We would prefer something much more subtle that we think complements her face much better.
Obviously she has to wear them and feel OK about them.
However:
We have to look at them.
We have to pay for them.
They are likely to last 2 years - fashions change.
Her current glasses which she chose are already quite strong on her face. I still don't like them at all after 2 years.
I suppose we could say she can have her choice if she likes them enough to pay for them herself out of her savings? Would that be fair?
