EVO do what I did when age induced myopia struck. Get yourself a set of Randolph frames and have prescription lenses fitted. Cheaper than buying frames from a certain chain opticians who told me if it aint on the shelf you can't have it. Even after postage from the USA.
How people can drive with the current trendy letter box lenses is beyond me!
Oh yeah bayonet arms as well so they fit nice and comfy under the headset or into the bonedome/skidlid.
