In addition to adjusting your camera you may need to use a supplemental diopter they range from a -3 to a plus 2 for most cameras A Optometrist can make a customized one this is all very simple and will easily work out for you. Make some good photographs

Thankl you everyone for your prompt replies. This octogenarian status certainly slows you down. I am Only n eed a few clikcks now 'left' eyed and remembered how to focus with the diopter. Only needed two clicks and I am nowq back in focus.

Thanks to you all.

I too have cataracts and have focus issues. The cataracts seem to move making my eyesight somewhat variable.
I do mainly landscape photography so focusing time is not an issue. I found using a number 5 or number 7 Optivisor
and dialing up a scene in live view works best. I have tried other devices with live view but you have to touch the monitor with them to work possibly causing camera movement. I have found it best to relax when focusing and not be concerned with which eye is dominant, that will automatically happen with both eyes open when looking through the Optivisor. Some long-range rifle shooters call this,"sinking into the rifle".

My left eye is my dominant eye. While I am right handed, I bat left handed and kick left footed. When I bought my first Single Lens reflex camera in the 1960s one of the reasons I chose Nikon was that the prism viewfinder was offset to the left (looking at the back of the camera). They still are.

After my cataract surgery I still needed progressive lens glasses. I always set the diopter adjuster for my vision with glasses on since I don't take them off when using the camera. This should make it correct for anyone with corrected glasses.

When I went to my optometrist in my ‘40s he said that everyone gets cataracts but they are not a problem at first. Eventually they should be addressed.

I lived with them until I was around 81, then the optometrist recommended getting the procedure. They call it a procedure instead of an operation because it is done on an outpatient basis.

Of course I was concerned about someone taking a knife to my eyes but I did it and it was no problem.

The surgeon studies your eyes and takes measurements. That took about a month. Then he did one eye. I went in to the clinic and they put in some drops. After about an hour he made some more measurements and put some marks on my eyeball. An IV drip provided anaesthetic. 15 minutes later the deed was done. He put a plastic cover over my eye for protection and I couldn’t get it wet for a day or two. Two days later He checked the eye and since it was good he did the other eye a week after the first one.

Both eyes are fine and my vision is good for distance. But now I have to wear glasses for reading. Since I was nearsighted before, the worst part of the cataract removal is the inversion of my glasses needs. I used to be able to read without them, now I need them to read. I used to need them for driving, now I can’t drive with them. I’m always losing glasses because I put them somewhere and walk away. The good news is that I don’t need prescription glasses. Cheap reading glasses from Costco or the supermarket or the hardware store work fine.

I recommend that you check with your optometrist to see if you’re ready.

Take the lens off the camera or turn off autofocus and defocus it as much as possible.

Point the camera toward a light colored, plain, well lit surface.

Looking at the markings in the viewfinder.... such as AF points on the focus screen or anything else... turn the little dial until everything in the viewfinder looks its sharpest. That's your best possible setting.

If you find the built-in adjustability isn't enough, often there additional diopter lenses that can be added to the eyeport of the viewfinder, increasing the range of adjustability. Contact your camera manufacturer, if needed.
