Hi there, I need an eyeglass prescription ... but I want to keep the glasses a bit tactical looking (and rugged of course). I have a small head (56cm/22'). It is even a challenge to find sunglasses for my head size ... but quite discreet tactical looking glasses for every day carry ... I need suggests from professionals ;-) It should not be too noticeable, that everyone is always staring at me). Yeah yeah ... I want it tactical looking because I'm peacocky ... you got me I don't know if that kind of glasses exists ... but I hope for the best! Have a great day!
