I'm also a glasses wearer and you have a few options;Option 1; contact lenses, means you can wear any eye protection you like and is pretty cheap if you Bly use the lenses for airsofting. This is the route I went down, and it's worked perfectly well for me.
Option 2; shooting glasses with prescription inserts, you can buy special nose pads for ESS and other manufacturer's glasses which will allow you to fit a set of prescription lenses behind the polycarbonate ones. It's not the cheapest option in the short term, but long term providing your prescription doesn't change they'll last forever.
Option 3; big mesh/polycarbonate goggles with a small slit cut in the frame at the sides. I used to wear a pair of mesh goggles which I'd chopped up to allow my glasses to fit underneath. Wouldn't advise it, not particularly comfortable, reduced visibility with the mesh and still the same fogging problems because of the glasses.
Option 4; LAZERBEAMS!!! Laser eye surgery is supposed to be pretty life changing, and will give benefits in all areas of your life, but is either expensive or VERY expensive depending on what type you have. This is the route I would love to go down, if it didn't invalidate my medical category at work for a year :-(
