Knoblock glasses

Hello fellow shooters
I recently bought a used pair of Knoblock glasses. I had my prescription installed and also purchased 1.00 lenses. The glasses came
  with some colored filters but the wrong magnification. What manufacture can I go to to be able to purchase  magnification lenses for the  Knoblock glasses?. I want to use these glasses strictly for air pistol.

FYI it sucks being older and you need this type of lenses

Champions Choice has some. I added 0.5 to my distance prescriptions

The lens test kit is out of stock. but this is what I used to dial in my prescription. Trying to get perfect vision a few inches past the front sight.

I have Champion frames and a local shop that my family gets their glasses from would fit lenses for a low cost. I should say I spent some time helping them get their eyeware geek on by showing the technicians the manufacturer's websites/products and showing them ISSF competition videos.

I use a +1 over my normal lens for air pistol in indoor competitions. YMMV.

I simply brought the lens holder to my optometrist and had him measure the needed prescription with the pistol in hand. He gave me prescription for the dot, which I what I wanted.

He then had the lab make the 37mm lens with my prescription and another one with frosted glass. This way I now have glasses with 2 lenses, one working as a blinder, so I can abide by the CMP rules.
