The DK 17M Dioptor only increases the range by 17%. I use it for extreme macro. It only gives you a slight increase. Simple fix, put your Glasses on..............................

On canon rebels the instructions say to look at the letters and numbers in the view finder and get them sharp

I had the same problem & my solution was cataract surgery. First check with camera manufacturer as much quicker & less expensive. Don't have to wear glasses now which makes photography more enjoyable.
Hope you find solution that solves your problem.

I can relate to the OP. Have had LASIK in the past. Distance is still good, but I need +2 readers. Pulling these on or off if don’t need distance glasses is a pain, and adjusting the diopter is the only practical (at least for me, YMMV) as the camera is always going up/down while shooting sports. For this reason I don’t use the LCD except at the beginning of a shoot to check for blinkies, etc.

I also did try glasses and found them to uncomfortable and distracting as it kept my eye further away

Glas to know that as, or if, I need it, can extend the adjustment. There will come a time where the standard may not be enough adjustment. Hopefully I am still shooting then. 😀

This is exactly what I do.

To adjust a Nikon camera diopter, activate the grid in the viewfinder if it is not on and get the small black lines sharp. When sharp to you your diopter is adjusted correctly.

If you need +2 reader then you would need to adjust the diopter about +1 from normal (which Nikon called it 0 because the normal position is -1).

I've been wearing spectacles since about the second grade ... lessee, that's about 68 years ago ... and I've been wearing graduated bifocals for about 15 years. As has been mentioned, you don't want to use the closeup part of your spectacles, nor any reading spectacles you might have, when looking in the viewfinder, although you may need that to read the markings on the camera body or the LCD. I think if you can see to drive, you can probably adjust your viewfinder to see.

First find another camera and see if you can adjust it OK, it could be your camera needs repair????

I had the same problem with my Canon 6D. I couldn't figure out what was wrong. It happened with all my lenses. I was convinced that something was either wrong with my camera or I needed new glasses. Using autofocus the photos came out fine, but they were blurry through the view finder. I felt like an idiot when I figured out what the problem was. There's a little wheel at the upper left corner of the eye piece to focus the view finder. That corrected the problem. Although I use Canon, I'm sure that this feature is on all major brands.

That's what the OP was referring to in his second sentence in the original post.

" I cannot adjust the diopter enough on my camera to allow me to see clear focus, it remains blurry."

That feature been on Canon camera forever. I think my film camera might have but my old rebels had it. To set it look at the bottom of the viewfinder where the scales and letters are. Twist the wheel till that row is sharp. Don't look and see through the lens but use bottom row and see how you do. Also due like the eye doctor does, this one or this one and rotate the dial. Good luck

Remove the lens and point the camera toward a plain wall that's a bright color. Adjust the diopter so that the markings on the focus screen and other things within the viewfinder are sharply in focus. You may need to "turn on" the AF points or a grid to have something on the focus screen for these adjustments. Don't worry about the "field of view".... you only need to adjust the diopter so that the focus screen is as sharp as possible. Then if the "field of view" is blurry it's because your lens isn't focused.

Yes, if you don't have enough range of adjustment in the diopter, there are little "corrective" lenses that can be placed over the viewfinder of most cameras to adjust their range farther.

You might also want to have your eyes checked. Or, if you happen wear bi-focal or tri-focal glasses, might want to get a "plain" pair to work better with the camera. These are sometimes called "computer glasses". (I also recommend avoiding the type of lenses that darken in sunlight... and don't wear sunglasses with polarizing filtration... all these may "mess" with what your seeing and lead to some unpleasant surprises later when you download your images.)

I wear glasses and rx sunglasses. Shots come out fine!
