Okay so I saw that claim but cannot get to the local gun store because of my job to check it out with my new red dot sight.
Any feedback appreciated.

Astigmatism - substantially negated by red dot PLUS magnifier?
- Thread starter Dingfelder
- Start date
The only thing that really fixed my astigmatism was toric contact lenses before I got Lasik. So a trip to the eye doctor would be the thing. It wasn't easy though. I also had dry eyes so the disposable contact lenses all felt like sandpaper in my eyes. Luckily I found an eye doctor who was above average who had my try Cooper Preference lenses and those were not only sharper focus, but also very smooth, slippery and didn't dry out. They were "3 month" lenses that had to be cleaned an re-used and I tossed them out every 30 days.

Thanks Eddie. I have the same thing -- really dry eyes, so contact lenses never felt good. I always felt their edge under my upper eyelid too -- not painful but quite unpleasant. "Toric" is a term I've never heard before -- is that a manufacturer or a medical term?

Toric means a lens that corrects astigmatism. And no, a simple plus lens will not negate astigmatism. Astigmatism means your eye needs 2 different powers 90 degrees apart. Contact lenses can correct for this but so do prescription glasses. You should be wearing eye protection when you shoot so why not have prescription glasses? 2 birds, 1 stone.

Hmm, I should look into that. The astigmatism doesn't bother me at all, but it wouldn't hurt to have something that corrects for it either.

I got a pair of Randolph engineering shooting glass's made to my prescription for shooting with open sights (muzzleloaders) basically they made the right eye focus at 3 feet and the left at 100 yds to infinity. Doctor told me it wouldnt work when I got the prescription. But they work great. They also have an adjustable nose piece that adjusts the lens up and down so the sweet spot is aligned with your eyes when sighting the gun. Regular glass's are too low and you either look over the lens or through the top where you dont get any focus at all. When you first put them on everything is blurry but if you wear them a few hours your brain adjusts and it's fine. Best $300 I spent. Cant say it will help astigmatism which i have. havent tried them with a red dot.

A toric contact lens has an oval shaped correction in addition to the spherical correction and the lens is weighted so the lens will rotate to the correct position in the first minute after you put them in to put the toric correction on the correct axis. As said above, eye glasses can do a similar job up to a point. Contact lenses do it much more accurately and with a slightly different depth of field. I'm not an eye doctor, but I was a test mule for an eye doctor who also was part of a development team that designed contact lenses for over 20 years and I picked up a few tips and busted a few myths. I had Lasik 11 years ago, so I no longer keep up with that stuff.

Wish my eyes weren't so dry; but my eyelids were still getting sore every day after months of wearing lenses. You do have me thinking of going to the eye doctor to get something to fix my astigmatism though. Hopefully he/she will know something about shooter needs.
