[Dooms]

I am not sure if anyone else here shoots on a Rifle or Pistol team but I guess i'll ask this question anyway. What kind of prescription shooting glasses should I get? (ex. Knobloch, Junker, Jaggi, ect.) I shoot NRA 3-position Smallbore and air rifle. I also do a little pistol, but I need the glasses for rifle shooting more. I normally wear small glasses and just move them around so there is less distortion but im at the point where my shooting is being affected by the glasses I wear. So, I decided to spend the $200 or so bucks on a good pair of shooting glasses. Can anyone help me out? Thanks
