Seems to be my day for recommending products -- I've used the Rudys with a Rx insert for years (first the Eqynox SX, now the Rydon SX) and though I am nearsighted with an astigmatism, I've had little problem with them. A little big of fogging on some days but other than that, riding and racing, no trouble. And I do like that I can switch from grey to red lenses quickly before the start of a race.
