I’m still trying to commit to some Persol - either the folding 714 or the 649. Probably.

I like the Havana colour frames and the colours that are relatively similar to it.

They often seem to have blue or blue gradient lenses in. I’ve never owned blue sunglasses and it seems to me to be a strange colour: I can’t imagine it greatly improving colour or contrast.

I’ll certainly wear whatever ones I buy when driving etc so I’m wondering if there’s any non-fashion related reason to buy blue lenses or whether they’re best avoided for actual use rather than fashion use.

Thoughts?
