Let me tell you, eyeware has come a long way. There are big names like Oakley, Wiley, Liberty Sport, ESS etc.. The military has special "approved eyeware" for their troops. Oakley has been the prefered vendor, and has saved many eyeballs. Botach or Ranger Joe's has an excellent selection of regular eyeware geared towards what our looking for. Hell, you can be cheap, and get some nice "over the glasses" shooting specs.
Now, if you want something custom, go to a good optometrist. Hopefully you keep your script up to date? See if he has shooting glasses. Sometimes they group them with "motorcycle" goggles(that's why some offices keep them off to the side). They have the same requirements. You can get them with as
many options as you can afford. I got a custom goggle/shooting/dri-eye, that totally seals around the orbs. I spent $400us for my set of progressive, blah blah blah, and still could have had more options. Look around. You might find a shooting glasses specialist. They do exist. If you go the custom prescription route, make sure you get "scratch resistant" and "anti-fog" coatings if nothing else. They can get expensive, but you don't have to break the bank. They are your eyes, how much do you value them?:
