I just had a Katzeye put in my 50D. I love it but it was expensive (at least it was for me)
I bought a split screen for my K20D. $16 on EBay. Took less than 5 minutes to fit and it works fine. I have a lot of manual focus lens that I use on my Pentax cameras and split screen is the way to go.

I bought a special lens that snaps into my viewfinder. This combined with the viewfinder adjustments,provide the correction I need without glasses. I then bought a pair of Hoodman eye glass frames that lets me flip up one of my eyeglass frames. Check this out:

I wear progessive lenses - have 3 prescriptions in one. Also have separate pair of "computer" glasses that I put on when I "come in the door". That all said, I wear my glasses when I shoot and have no trouble. If there seems to be an issue, I trust the auto-focus. I don't notice any problem when I manual focus.

The problem for me usually starts with manual focus when the lens is wide open (f/1.8 or wider). There I need the assistance of the etched focusing screen.

What has been your experience? I wear graduated bifocals (no line), which I usually leave on when I am using the viewfinder. Will I get better or worse results (focus) if I take them off.
I bought a diopter for my camera (under $20) that matches my correction for distance. I have noticed that it makes a difference even when I am shooting auto. I could never get the right part of my glasses lined up with the view finder.

Adjust your viewfinder, slide glasses to top of head when shooting or hang em on a croakie.

I used split screens on one of my Mirandas, great for focusing except with tele lenses, one half would black out, my understanding was that it was a common problem with tele or slow lenses, Bob.

I succumbed to the old lady chain for my glasses. Sigh. Now I can just slide them off my nose and drop them with out worrying about where I set them or as I was doing bending them while trying to hold them while focusing.

If you adjust the diopter on your camera for your eyesight without your glasses ... you won't see much of a difference. I do that now and then but then I forget to remove the glasses .. so I have to reset it again.
I have no line trifocals .. so I can get the camera to focus in just fine but I can't see the photo on the screen w/o my glasses ... it's a vicious circle.

When you focus without your glasses you're asking the diopter control on the camera to do the work of your expensive prescription spectacles. Not impossible, but not all that great an idea if your vision needs serious correction.
If you wear bifocals you'll experience the least eyestrain if you focus through the upper (distance vision) part of your lenses. Then use the diopter control to maximize sharpness in the viewfinder.
Incidentally, it's a lot easier to adjust the diopter setting accurately if you turn on your camera (shutter button half-press) in order to illuminate the exposure data in the bottom or right stripe of the viewfinder, and focus on that rather than on the image itself.
Happy shooting, manual focussers!

Thanks for the tip about split circle focusing screens. I wear no-line bifocals, too. I am not always pleased with the auto focus and have trouble seeing through the viewfinder to manually focus. I see a trip to the local camera store in my near future!

This is exactly what I do as well, not only for photography but for birding through a spotting scope. Plus, having your glasses on of course makes it easier to use the LCD screen for focusing if you ever do that.

The Hoodman frames are a photographers best tool!! You can adjust your viewfinder for no glasses and never have to pull your glasses off. Just flip up your lens, focus and shoot without taking a chance of dropping or looseing your glasses. You never know when the next shot will come and having to remove your glasses while trying to focus with glasses in hand can be tough. There are a few other brands out there. Its worth checking into.

Most of these comments involve camera/lens offering auto focus. Nice if you have it, but in my case only one of my five or six lenses is an auto-focus. That's the one that came with the camera, (Pentax K2000) and it's OK, but not the top of the line. I have to manually focus all of my other lenses, although the little "In focus or not in focus" dot in the viewfinder does work even when the lens being used is not auto focus. I use tri-focal glasses, with the lines, but one of my eyes - the right one - has 20/20 vision in all but closeup situations. Still, not bad for 81 years old.

try adjusting the dioptic adjuster near the view finder (CANON)
to get a clear picture....double check the focus with and without glasses to check
after adjusting the adjuster + or - check it against auto focus to compare
if you don't want to fool with the dioptic adjuster use your glasses
