I find my regular prescription glasses to be better for mtbing then my cycling glasses because they don't tend to fog up as bad. Knock on wood I have had little or no problems with them as a result of mtbing. Doing trail work on the other hand tends to scratch them right up every year.
Switching to road biking, every once in a while like last night I forget to wear my cycling glasses and I always regret it. My cycling glasses are far more aerodynamic then my prescription glasses on the road and therefore are far better due to less wind in my eyes. Eventually I will get prescription cycling glasses for the road.
My recommendation to you is, if you are getting prescription cycling glasses for the trail only, I would tend to get something well vented and less aerodynamic so they will fog less. The fogging tends to be a real problem as the temps start to get colder and especially when the temps drop below 32 the fog can turn to ice and then it doesn't go away when you get started up again.
