if you had -2.75 perscription glasses with thick(ish) frames would you pay extra money for 1.6 thinner lenses OR Crizal Alize + coating? Thanks in advance!
I'd get professional advice from my optician - that's why specs are pricier from the High Street than from a website. You get all the associated "niceties" etc.
The link was for others to see the opinions on thinner lenses for your moderate topic correction. The coating vs hi index argument is flawed without knowing if you would benefit in a cosmetic manner. Otherwise the question is "do you want a thinner lens or one with an antireflection etc. coating.
