Need a lens made

[leedubno@gmail.com]

I have an Olympic 25mm lens holder that my optician cannot make a lens for. I tried Champions Choice, but they do have an optician to recommend.
Anyone have a suggestion ? I am trying to use my distance prescription with a +.5 correction added to it.

Thanks, Lee

Neal Stepp is a wizard when it comes to lenses. He has made a couple for me. He can even take you old set of glasses and have lenses made, not just monocle lenses.

Any optician can make you a lens and 25mm should not be an issue. The question is what prescription to fill. As a rough determination is to add +0.75 diopters to your current prescription. This is most common way to get to shooting prescription but it can vary from +0.5 to +1.0
The best ways is to find an optometrist that can do a shooters eye exam and they allow to bring a gun into the office and actually can work with you to fine tune the corrective lens as you are actually taking the aim.

If no shooting exam available - just go with +0.75

Make sure to ask them to put a notch/mark on the side of the lens so you can alway properly orient it in a holder even if have to reset and to avoid accidental rotation. If you have astigmatism this is super important to avoid accidental lens rotation

Because shooting glass lenses are typically round, you can fine tune the axis yourself. There are all sorts of astigmatism test patterns on-line you can print out. It's nice if the lenses are marked, but it's hardly fatal if they aren't. You may even find that you can do a tiny bit better than the mark from the optics shop due to variations in the measurement at the optometrist and the lens grinding/cutting operations.

Talk to www.customsightpicture.com, get their kit and use it. If you can actually visit Dr. Toler in Richmond, VA, that's best.

'Clocking' astigmatism, rotate the lens until a window frame appears 'square'.

As for round lenses, I've dropped off several holders to have lenses fit to them. None of them fit ... because the lense holders aren't ROUND. They're rolled from a milled strip. And lenses are somehow cut with a tracing system with a follower in the lense frame.

After who knows how many years ... I still haven't figured out how that works... from a toolmaker/machinist/mechanical designer background.

Not that I had any major issues ... worst case they're a bit loose when oriented correctly... which a little patch or 2 of tape to tighten the grip can fix.

But ... next round of this gets my distance prescription sent to a 'specialist' ...

I cut my own. Got the lens blanks from a Gmei Optical on Ali Express. Just under US$ 6.00 for 2 single vision scratch, UV, reflection, aspheric coated blanks which are 75mm diameter. Cut out a 32mm circle on my CO2 laser and added the edge bevel with a diamond file by hand. Price was so low I bought a range of strengths and just tried them until I found what I liked. After 8 months or so I swapped out for .25 lower strength and decided I liked that better. Lens is as good as the $35 + a few bucks shipping official Champion lens that ended up not being strong enough.

I also got a complete set of glasses from them with my distance prescription on the left and my iron sight prescription on the right for the powder range where eye protection is required. I use the little suction cup stick on iris and a clip on blinder on them. US$ 20.00 delivered for the glasses.
