I have two deer rifles. My primary is a .270 (3X9 scope) and my secondary is a .243 (4X12 scope). My vision is 20/20 while wearing glasses. I am 61 years old. This season on my first trip with the .270, the scope image did not appear to be as powerful. I switched to the .243 for the rest of the season, and it worked better, but although the sight picture was clear, it did not appear to have the same level of power. Same thing with my binoculars. Has anyone else experience this?

Put all three on a consistent power (may not be able to with binos) and compare against a scope you or someone else is confident in and see what irregularities there are.

If all three have changed, this indicates to me a change in your eyes/perception of the sight picture rather than any mechanical issue with the scopes or Binos

I’m 81 and scopes and binoculars work ok. I wear my glasses when I shoot with iron sights. But, gotta admit, I’m not as good with a pistol as I used to be. It’s best if I use a rest instead of off hand.

Also check the rear objective adjustment. The rear objective will be able to dial the "focus" of the reticle. Check this. I get in a lot of rifles with a similar concern only to find out the rear objective is badly out of focus.

All of the above are valid, but also consider the last eye exam and how old your glasses are. If its been a year or more, I would suggest getting another exam. I see people all the time who think they are still seeing good and they are far from it. Vision can change slowly and you adapt pretty quickly to small changes, and before you know it there is a big change you are unaware of. I have even seen people be completely blind in one eye and not know until they show up to their eye exam and cover one eye for testing. It is fascinating how some people can not tell something is off.

Get your eyes checked. This fall on 3 of my rifles which I've shot and had for years were blurry. I thought oh well and adjusted the focus, I'm 67.
I had an annual eye exam today and when the lady had me cover my left eye and read the chart everything looked like Chinese letters on the smallest size.
Guess what I need new glasses and my right eye needs more correction.

Good luck,

I don't wear glasses, but I am probably overdue for an eye exam as I am 66 and can't remember the last time I took an eye test.

It is amazing how many people at 66 think they see fine, and get tested and find out they shouldn’t even be driving without glasses (or cataract surgery).

I see people every clinic day that say they have no issues with their vision yet are seeing in the 20/50 to 20/60 range…denial is a great thing. But as mentioned above, sometimes you just adapt to the slow changes and dont realize that your vision is pretty garbage, but can be fixed.

Unless I am missing something one scope is 9 power and the other 12 power at maximum setting. If both are clear and you had them dialed to the maximum setting, that is a 3X difference in power.

Eyes can do strange things, but with a pucker in the middle of my vision in the right eye and vision that varies between 20/25 and 20/40 throughout the day it is what I have and proud to have after 5 eye surgeries.

First I would get the vision checked
Next adjust the diopter for the best view to you.

Truth! Out of the blue around 50 years old, had same issue, ended up needing a prism, then few years later T2 diabetes and vision has not been near as good. Does effect any scope, binos and spotting scope for me now.

Here's a tool for your toolbox. The last year before I retired, my vision had degraded to where I couldn't read street sign names and I passed my last driver license renewal by making a couple of lucky guesses. After I retired and moved to my ranch, my vision started improving over the span of several months, I had to adjust all my binoculars back to zero. My vision is like nothing ever happened and everything at any distance is clear and bright. The only things I can come up with is that after I retired, I didn't sit and watch computer screens for several hours a day anymore. My blood pressure also went from needing to medicated, to no medication and normal blood pressure today.

There is a more likely scenario which you are dealing with, tho no way to prove it….but heres the explanation i would give for what you described above:

Eyes naturally shift toward far sighted as we go from mid adulthood to late adulthood. This is different from the onset of presbyopia, or the lack of focusing ability, many people will see a shift to a more far sighted (also why a lot of people think their lasik wore off, buts thats a different subject). This stops and reverses course as cataracts start to form , and cataracts create a near sighted shift. So many people will experience what you did, good vision that gets poor which then gets better on its own. This all typically starts happening late 50’s and then the reversal starts in the 60’s. Your timeline fits perfectly

The early stages of cataracts don’t typically cause much trouble with vision other than a shift in the prescription, so for people like you, there can be no rush to do surgery. But eventually the shift will continue and you will see well up close but your distance will be lousy again.

I’ll see what happens (literally). I just couldn’t help but notice the immediate difference when I retired. It started getting better in just a few weeks.

What you may have experienced if it was just a matter of weeks is a relaxation of accommodative spasm, so you may be correct it was just not looking at screens and such near as much.

If I wasn’t looking at one in my car, I was looking at one on my desk so that was the best I could come up with when it dramatically changed, in a good way, so quickly.

Cataracts . Can cause slow progression problems that one hardly notices. My wife works with a cataract surgeon and you would be surprised how many patients say
they didn’t realize how bad their vision was before they had surgery.

I always had good vision and then all of a sudden I found out my left eye was carrying my right eye, which is my shooting eye.

Both eyes open, saw great. Left eye open and right closed, saw great. Right eye open and left closed, vision was worse.

An eye exam is worth the piece of mind but nice new scopes will help too.
