Any ophthalmologists on board re: dot sights?

I had recent cararact surgery to correct my dominant eye vision to set it for distance vision. Following this surgery I found that I could no longer focus my dominant eye on fixed sights (sights were very blurry). I also found that using a dot sight with my dominant eye resulted in a crystal clear sight picture and dot.

I discovered this morning that using a rifle telescope with my dominant eye resulted in very blurry crosshairs. I guess I expected the crosshairs to be clear just as the dot sight was.

Wonder if I will have to go to dot sights for everything? Can anyone explain what is going on here?

Can you adjust the scope? Mine all have adjustments at the rear lens. Try low power reading glasses to see you sights. I have some 1.25 diopter safety glasses that I use for target shooting.

I'm not an ophthalmologist, but I did also have cataract surgery a few years ago. After talking with the surgeon and convincing him that I understood basic optics from photography training and explain that I wanted to be able to exit a patrol car and see my front sights without glasses. I also felt that if the depth of field was sufficient to overlap between the two eyes, setting my dominant eye to focus at the close end of near to include the end of my arm.... out, and the non dominant eye at a distance. During the day I wear no glasses at all and can read, do paper work, shoot, basically like I am 21 again. The depth of field overlap and brain work together to let me see almost perfectly. Reading and paperwork are easier with glasses, but I can function completely without them.

At night, when my iris opens and there is no depth of field overlap, I wear a very low power set of prescription glasses appropriately set for each eye. This is only to keep my eyes from getting tired and watery from overwork. My brain will compensate for most so I can still function just fine without them, short of reading small print.

He did a bunch of tests, and some calculations and ordered lenses to the spec he came up with. Had to wait a couple weeks for those to arrive, but after the second surgery my eyesight is better than it has been since I was a very young man. It was a blessing.

I think MAYBE you went the wrong way with your dominant eye for shooting.

I just needed to not have to rely on glasses to shoot and he gave me exactly what I needed.

I had cataract surgery last year for my right eye(right handed) with a dominant left eye.
Bad combo for shotgun.
I am now right eye dominant!!!
I went with single script distance vision lens.
My shooting glasses have a right lens for pistol shooting that is set up for pistol shooting.
I had to change that lens to a clear lens for rifle.
We have an iron sight 22lr match coming up and the clear lens right eye is very sharp with 20/15 vision.
This is on a 52D Heavy Barrel and Olympic front and rear.
Your rifle scope should at minimum have a diopter adjustment at the eye piece.
Try varying the diopter adjustment.
All of my target scopes have parallax adjustment also.
If the red dot is sharp, your vision with scope should be ok, check another scope with diopter and parallax adjustment-Richard

I was incredibly near sighted all my life. When I had the cataract surgery all the doctor told me was that medicare paid for the "standard" replacement lens and it would cost a few thousand dollars if I wanted custom lenses. He did not tell me that I would wind up super far sighted and never again be able to read a book, use a computer or shoot a hangun without glasses!

I am not a long distance truck driver! I do not need to see a mile ahead without glasses!

That was several years ago and I will never get over being upset at the results which turned my world "inside out." Had I been told in detail what I could have had for $$$ vs. what I would get for "free" I would have gladly spent the thousands of dollars for both eyes just to be nearsighted again and be able to read the small print - or even to read a newspaper! For what little it is worth, I do not go to that opthalmologist for anything anymore.

Thanks for the suggestions I received. I just tried focusing on fixed handgun sights using some of my pre-surgery reading glasses and found that using readers in the range of +1.5 - +2.0 allows me to focus on handgun sights. I will try the readers and adjusting the eyepiece on my scope next time I take a scoped rifle to the range. I appreciate the suggestions above and those I received via PM.

Shooter Granny - there is another solution that MIGHT have worked for you. I had my dominant eye set for distance vision and my non-dominant eye set for close vision (reading). I believe this is called mono-vision and for many people the brain will automatically decide which eye to use. I had used mono-vision years earlier with contact lenses so I was pretty sure this would work for me. My goal was to eliminate the need for glasses for either distance or near vision. It worked very well for me but it looks like I may need readers for focusing my dominant eye on fixed sights. I think I can live with that.

There was no extra charge for this setup since both eyes used simple single vision lenses. This is an alternative to the several thousand dollars required to achieve similar results using lenses that allow multiple focus ranges.

Did you adjust the diopter on the scopes eyepiece? If it doesn’t have one go to a gun store that has a scope that has one and try it. Not sure what your scope set up is.
