Our lens recognition system will recommend the most suitable lens package for you based on the prescriptions values which you have entered.
When your prescription is a high minus or plus (for example, -5.00 or +4.00 Sphere and higher), we would advise you to choose a frame as small as possible (preferably in plastic) in order to reduce the thickness.
Additionally, aviator frames are not recommended for prescriptions over +/-2.00 Sphere as they have a large lens diameter.
