Poor vision and zeroing

[migikesagiri]

So This is something that I haven't really seen anyone talk about before. I'm looking at getting corrective surgery to fix my very bad vision (hopefully in a couple of months.) So in the past and currently I shoot with glasses, which can me covinient as I always have some eye-pro. Do you guys think that getting the surgery will cause me to have to re-zero my rifles? Or if your prescription changes, for that matter?

It shouldn't matter.

The most common issue is when you get older, your eyes don't accommodate (adjust for distance) as well as younger eyes.

The trick will become focusing on the sights and the target at the same time.

I've had both eyes done for cataracts (intranet-ocular lens implants); I now see better than 20/20 in each eye. However, I can't focus for close work; I need "readers."

To shoot, I wear a lighter reader prescription (+1 instead of the +1.5-2.5 I usually wear for reading or computer work. This allows me to see the sights well, with a little blur on the target (more distance, more blur).

It's different for everybody; but overall, you'll be able to to find a solution that fits your needs.

Now I'm trying wearing a +1 reader on the right eye (for sights) and a zero-correction for my left eye (for target) and shooting with both eyes open like I used to with glasses.

Once your surgery is complete and you're ready to shoot again, you should at least go out and re-confirm your zero. Everybody's eyes are different, and everybody acquires targets and sight alignment/sight picture differently. You may not have to readjust your sights at all, or you may have drastic changes. It's better to be safe and at least re-confirm. Besides, it gives you an excuse to go shoot at least....LOL.

As an addition to the above: If you're using optics, the only adjustment you should need is the "diopter" adjustment, usually like a "focus" ring on the eyepiece (not the Parallax adjustment of some scopes). Eye-side optics are focused to infinity, the diopter adjust is correction for near or far-sightedness. If it was adjusted to your old prescription, you'll probably need to back it down closer to zero correction.

If using optics, yes. You should at least reconfirm your zeros. Lenses, especially prescription lenses can induce extra parallax when looking through a scope and change your eye relief. I've seen this problem several times as a marksmanship instructor especially while transitioning Marines from iron sights to ACOGS. If your stockweld and eye relief isn't perfect while wearing glasses (meaning the focal point of your glasses and optic are perfectly in line) it can induce extra parallax. Nixing the glasses will probably change your eye relief and possibly your stock weld.

I recently had to get progressive lenses because of my inability to focus the front sight and the target. It has been some getting used to nodding my head to get the sight picture as necessary.

I have not heard the need to resight a rifle scope though for different vision problems. I sighted scope should work for any shooter that shoots that rifle.

Thanks for the input.

Something to think about. I was almost legally blind. Severely near sighted. I was always right eye dominant. I went and had laser surgery done. Now I'm 20-20 and 20-15. Almost perfect. The only problem is that my dominance switched from right to left. So make sure any optics you get has a good right eye diopter.
