Somehow I made it to age 62 without ever having used a scope. Hard to believe, isn't it?

Anyway, I recently got a scope and have noticed that when I am done shooting my vision is blurry for a half hour or so after. This has never been the case with open sight and peep sights.

Does this happen to you?
 
No, that doesnt sound right at all, have never heard of anything like that happening. Might be a trip to your optomotrist would be in order.
 
There is a principle called "accomodation" which is a normal function of ocular physiology. In simple terms, accomodation is when surrounding muscle tissue changes the shape of our ocular lenses as our needs for focus change.

My personal opinion is that you are simply experiencing a "slow return to normal lens shape" after you spend time in your scope. You may even notice a straining sensation as you learn to use your scope. You may also be straining to see objects far in the distance through a low power scope.

Like all other muscles, the response times of ocular muscles (aka Ciliary muscles) slow as we age, but muscles can still be trained as we age as well. The training just takes longer. I believe you will notice a shorter time to return to normal vision with more and more use of your scope. The more time you spend in your scope, the more you train your eye muscles, thus they will eventually get better at refocusing once your shooting session ends.

Happy Shooting!!!
 
You might also check to see if the scope is focused for you. There is an adjustment ring at the back objective lens that allows you to focus the scope for your eyes.
 
Yes, this happens to some small degree whenever I look through any lens for an extended period. I notice it most when I shoot with one eye closed. I find it more relaxing for my eyes to shoot w/ a patch (of sorts) on my left eye.
 
Eye fatigue, which is simply what I call it, has occurred to me, also. Generally, it's when I'm on a bench for extended periods of times and/or using cheaper-grade scopes. I've never had it happen on a Leupold or Nikon, but I've had Tasco and Bushnell scopes go black on me when I look through them for too long.

After the shooting session, the eye isn't blurry as you said, but I can tell it's working harder on focusing properly. Check to make sure your lens is focused right, and if you have an objective lens that focuses in yard increments, that it's set to what distance you're shooting.

Good luck.
 
When I shoot with my non-aiming eye closed I get gawdawful eyestrain in the aiming eye. Looks like someone jammed their thumb into it, and doesn't feel a lot better. Try shooting with both eyes open it might help.

Yep.
 
thank you all

I went to the range late this afternoon to try it again, and noticed that even though I shoot open/iron sights with both eyes open, I am squeezing my left (non-shooting) eye closed and sort of straining my right eye with the scope.

Also, it is a cheap Gamo brand sight made for air rifles and rimfires, so that doesn't help, I'm sure.

I'll try to focus it the next time and pay attention to not closing the left eye.

Thanks again for all your help.
