First time glasses (progressives) and wonder when I use my grain focuser do I use the bottom, top, none? I have a schnider grain focuser if it matters and it looks like you can adjust the optics.

Thanks!
 
Edit: oops, my eyes and brain weren’t properly connected. You are asking about darkroom grain focuser and I replied about focusing loupe for LF camera. Sorry; not sure if there is a correlation or not. But leaving my errant comment for your amusement.

With both normal bifocal and progressive I use the reading part, with fixed loupe. I recently got a focusing loupe and did the same but did not experiment too much with it yet. I had a pair of glasses made with just the reading prescription, which helped for both reading and view camera ground glass. Much easier on the neck.

What Brian said. You will quickly find that you will automatically use the reading range for this and similar tasks.
 
I'm w/ Brian. My bifocals have me craning my neck at odd angles, stairs are a dangerous thing now, and I drop or turn things over much more using these %$@!! things. Next time it will be single vision, and 2 pairs of glasses.
 
In the darkroom, I wear drug store reading glasses with a neck strap, or no glasses at all.
And with grain focusers, just use what works for you. For me, that is usually no glasses, but the middle section of progressives also works.
In the case of my eyesight, I don't need glasses for things one meter away. For closer or farther, in varying degree, I do.

I am assuming that I want the line going through the glass to be sharp? It has been so long since I have developed anything.

Thanks everyone for their help. Hopefully in 12 weeks I will have my new enlarger and finally printing.

I find it much easier to 'tune' the scope to my eye without glasses on. I find glasses just get in the way. Try this first.

I just tried this and it works better for me too.
 
I just got an upgraded prescription and two pair of glasses. A pair of outdoor/normal bifocals and a pair of computer glasses which I got in a safety glasses frame and polycarbonate. Useful in the shop and the darkroom as well as the computer.
 
Strange - I use my focusing loupe with my glasses all the time, both progressives and readers, but I use my grain focuser without glasses. Maybe it's because I need to get my eye closer to the eyepiece than the glasses will allow for comfortable viewing.
