Sorry, but welcome to the club. I only shoot for groups and sighting in my rifles.
That said, I do the best I can.

Back in the 50's & 60's my Dad had shooting glasses, you might check into them?

 

I have my share of troubles too. Its the pits. Try shooting slower and looking away from the scope after each shot. I find starring through the scope too long causes issues. Give your eyes a break between shots.

 

What caused that with me was not carefully adjusting the eye piece to get the reticle tack sharp. That is all the eyepiece adjustment is supposed to do. Focus the reticle. Plus not having the AO adjusted exactly. My eyes were kind of bouncing back and forth focusing image vs reticle. When I was more careful with that most fatigue went away.

When I had to get progressives (bi-focals) I had a spare set of glasses without the upclose adjustment of progressives.

 

Do you shoot with both eyes open? If not you get eye strain faster because you are overloading the aiming eye, the having to refocus it to match the non aiming eye between shots. A simple blinder on the scope to block the non aiming eye (cut out plastic from a milk jug and tape it on) might help a lot.

 

I feel your pain, glasses suck! Try to get the best focus you can. You might try staring off into the distance once in a while to give your eyes a rest. Also make sure you are blinking enough to keep your eyes lubricated. I wish there was a good fix, but I haven't found it yet either. Hopefully this helps some.

 

If you are near sighted, you might want to try soft contacts. Work great. If you get contacts, don’t get the bifocal kind. You want a straight look.

Might also want to try to find a scope that has a more generous eye relief. And finally to maximize I relief, turn that power down. And do work hard on getting the scope properly set for your focus.

I have that exact same problem when shooting IHMSA UAS class. The scopes eye relief is so tight, Going to PRS scopes, my issue was relieved.

 

Being right handed and left eye dominant, I found putting a patch over my left eye helps. If I close my left eye it blurs my right eye. With the patch, I can keep my left eye open. The Diabetes and Glaucoma takes a toll on my eyes a lot anymore.

 

I carry eyedrops in my range bag

 

I’m 74 and fight the same thing. A top quality scope does help IMO.

 

+1 lubricating eye drops Before shooting
+1 on taking the little bit of time ensuring the ocular is adjusted for reticle focus for your eye (you only have to do it once but do it right)
Having an Adj Objective helped me. The graduations are possibly close but sometimes not perfect. I set the AO at say 50yd, look thru and tweak the AO for the sharpest view.
I cant look too long thru the scope, if I dont get the shot off within 5sec I need to look away, Breath, blink (I do 3 times) and get back to it. That all helps reset the brain and eye.
Be patient
Have fun
Sometimes I have a poor vision day, if it aint working out, quit and go do something less demanding.

 

I also wear glasses. Having been blessed with great vision for my first 70 years of life, I now have a pair of prescription glasses at age 72. This may be valid for those others with a mild prescription, but I can adjust the focus of the scope enough, that I can shoot without wearing my glasses. I can do this with Weaver 36x, 24x and 6-24x, scopes.
Your results may vary.

 

I normally wear glasses but when shooting I put one contact lens in my left to watch the flags and nothing on my right. Tried glasses twice and they didn't work for me. Less eye strain shooting both eyes open.

 

I had my cataracts done two years ago and it made a big difference for me. My scope is an Athlon 10-40X56 and I shoot both eyes open watching flags and target.

 

I had/have the same problem.
Now I use Optrex eye wash before going out to the range...and a secret weapon!
On another forum one member mentioned how he was advised to put a smear of 'organic castor oil, hexane free' over his eye lids. Seems that the castor oil is good for skin, and in this case it helps by soaking into the eyelid skin and making the tear glands work a bit more freely.
Does not irritate or hurt the eye.
I took that advice and now my routine is an eye wash about 1 hour before the shoot, and then castor oil on the eyelids (right eye is my 'aiming' eye, but I smear it on both eyelids).
Made a foam blinder for my scope to 'blind' my left eye (shoot with both eyes open).
I'm 78 real soon, and have cataracts developing in both eyes.
Can see much better through the scope now, and don't get that eye strain that I had before.
These blinders are just cut from a scrap of foam. The 2nd photo shows the green foam blinder sitting on my Sightron 45x45.
Total width of either blinder is ~5¼" and height is ~3¼", 3/8" thick. So it doesn't have to be a huge flappy/floppy thing. The black foam is only 1/4" thick and it sits well too.

I've seen similar setups. You must shoot without flags to monitor.

 

Yes, I shoot indoors BR.
We have a club member who has no sight in his left eye. He shoots outdoors too, and as he can't see the wind flags he aims at the target and then waits for other shooters to fire!
Then he knows it's probably OK to fire too.

 

Whatever works.

 

Thanks all. I will try the blinders. I shoot with left eye closed. I find when shooting for groups, I did better with one eye closed. I have adjusted the ocular but will check that out again incase it has moved. Now that I can afford nice stuff my eyes are failing me. Although, I always have had bad eyes. Wore glasses since I was a kid. Have tried contacts, but I don't really like the feel. Also have astigmatism, which makes things that much harder.

 

I have to put drops in my eyes every night at bedtime. Dr said make sure you do it or you will, go blind. Of course I said OK!

 

As a person that was blessed with raging glaucoma, you may consider going to a specialist and have a work up done on your eyes that goes beyond just checking to see if you need glasses. A good ophthalmologist will check your eye pressures, optic nerve health, field of view, and overall health of the eye itself. Just a thought you might consider. You might be able to save some more trouble down the road if you catch something early.

 

The woman I see checks the pressures and her assistants run field tests on me. I don't know about the nerve part. She is suppose to be a specialist. But, in this little town I don't trust any of them much. I was raised in St. Louis and probably should have stayed there. I was lucky they did a good job putting my pacemaker in. It was an emergency case so I didn't get to go to St Louis.

 

Hoping someone here can shed some light on this. I wear glasses and like precision shooting. I have always had issues focusing on the target...my eyes fatigue fast. I used to think it was the scope (cheaper side). I now have a pretty good scope by all counts and am still experiencing pretty bad fatigue. My shooting eye gets blurry after about 20 rounds and then the target start to bounce around. My groups open up and ruins my day.

My prescription is current.

Anyone have similar issues? Or know of fixes?

Do you shoot with both eyes open? If not you get eye strain faster because you are overloading the aiming eye, the having to refocus it to match the non aiming eye between shots. A simple blinder on the scope to block the non aiming eye (cut out plastic from a milk jug and tape it on) might help a lot.

Just to add a little to @Pat McCoy 's good advice. If you use a blinder, have one that is a light gray or beige color. Not black as that is almost as bad as closing the non aiming eye. There are also blinders that clip on your glasses.

If a blinder is not for you then consider a couple of pieces of frosted scotch tape on the shooting glasses lens of the non aiming eye, works the same as a blinder.

 

A lengthier path, but having a single vision lens for your shooting eye, with a focal point specifically calibrated for the scope, makes a big difference.
Similar to when you shave, your reflection is too close for glasses, but too far for without. Your eye is trying to correct and gets tired.
Finding an eye doctor that both understands and appreciates the optical physics as applied to shooting is the hard part.
Send up a signal flare for one on this and other sites. They're out there and can help you find one close to you.

 

My 2 cents:

Adjust the eyepiece carefully against a white background, so the reticle is super sharp

Adjust any parallax carefully to get the target sharp

Abort the shot process if it takes more than 4-5 seconds. Look at something else, and restart the shot process

Get as much light onto the left eye as possible, but don't let it see the target. Closing one eye will increase the size of the pupil in the open eye to bring in more light, giving less field of view. Get a semi transparent blinder, and tilt your head slightly to observe wind flags below the blinder

You may get mirage from the ground, (and obviously the barrel in a centerfire gun)

I would normally advice to skip the glasses since you already have an eyepiece (ocular) -and the frame may interfere with the field of view- but if your astigmatism is bad then maybe you should consider a separate lens installed exactly at the angle your astigmatism is worst. You will have to twist it once behind the scope to get it right

There are of course shooting glasses that will filter out wavelengths that distorts your vision slightly, but any lens will filter out some light and could potentially make things worse

I tried eye drops, but still had good and bad days

Again, just my 2 cents, hope you solve the issue.

 

As with the previous reply, I would not buy a scope without parallax adjustment if you might shoot at ranges below 100yds. Yesterday I struggled shooting with a good Vortex LVPO scope at 50yds and focusing on the reticle. I switched rifles that had a parallax adjustment and the reticle and target focus was night and day. Old eyes, with both scopes and metal sights is problematic. We have to adjust, spend more on better optics, glasses and red dots!

 

I shoot without the glasses. Adjust reticle focus and parallax for my eyesight. 80 year old eyes.

 

I won't be 70 till October 7th. But, with the health issues I feel more like 90 or 95. My neighbor is 82 and in much better health. We go into a store during hunting season he leaves me in the dust I can't keep up. He complains about being so small. I said that's probably playing to your favorite. At 5'5" and 126lbs, he may live to 100. His father did and his mother made it to 99.
