I know there must already be a thread on this somewhere, but I'm buggered if I can find it. I have typical 'old bastard' vision. From a metre away my vision is excellent, good enough for a pilot medical without glasses, but from a metre and closer, it goes to hell in a basket. I am looking to buy some wrap-around sunnies like the 'Wiley X' range or similar, with prescription lenses that are bifocal, ie clear from the top to around 2/3rds down, and then about +1.5 for the last third. Has anybody bought any similar sunnies? if yes how do you find them in use, and where did you buy them?
