M8.2 Focus problems with progessive glasses

[pwratt]

I have a M8.2 and wear progessive glasses and have some problems regarding focus. can anyone recommend a solution ... remove the glasses when shooting ... use Dioptres?
Thx Phil

you should get your prescription for 3 meters and then have a lens made that will fit in the Leica adapter-then shoot without glasses

Ahem... two metres.
Better get a diopter and shove your glasses onto your forehead when shooting imo. Try out the strength of the diopter you need with your optician's try-out lenses before you decide which diopter - these things cost 100 Euro! Leica has not supplied the empty adapter for along time,asi t is near-impossible to have 10 mm precription lenses made nowadays.

Progressive lenses have very poor optics. When you use a bifocal, or trifocal with lines, it is like having two (or three) single vision lenses glued together and you then have the clear optics (lens material considerations aside) without the distortions of progressives. Prior to changing lenses, make sure that as you press the viewfinder against your progressives, you aren't then pushing the lenses upwards and then trying to view through the intermediate zone of the lens. This greatly reduces your clear view. Of course, all assumes that you have a current prescription and that the optician placed the various areas of the progressive in the correct place. Contact lenses and lots of rewetting drops works great, but horrid for your near vision.

I wear progressives and have no problem whatsoever focusing my Leicas using the upper (distance) part of my glasses. Only the LED's and frameline borders are set at a fixed virtual distance (unlike an SLR where the entire field is fixed due to the ground glass plane) and that distance is 2m, well beyond the reading part of progressives. Also given the limited close-focus range of the M lenses it would be quite unlikely that you would ever find a subject you could focus on that would require looking through the lower part of the progressives to see clearly. Progressives have a very rapid progression between near and far, much swifter than I imagined until my optometrist showed me.

For a long time I needed a +1 on my Leicas in addition to my glasses, but then I went for an eye exam and found that my Rx had changed! With the new glasses I took off the diopters.

I used to have problems focusing with progressives. You need to make sure that your focusing at the same spot in the lens. I had Lasik and no longer have any problems. A diopter would probably work well.

I tried progressives and they were a nightmare. They made computer work difficult, focusing my 4x5s impossible and focusing my Leicas spotty. I ended up with a good pair of bifocal transitions and a special pair of studio reading glasses for 4x5s and the computer.

I tried diopters for my M8 but found that using my transitions bifocals was easier. I could just leave them on all of the time. I lost the easy viewing of my 24 mm frame lines, of course but, short of surgery, that's life.

Not all progressives are alike. Lenscrafters tried to BS me that they were, and that I was just not trying hard enough to get used to them. A friend who is an OD told me to find an optician who was licensed to dispense Varilux Comfort. She also told me not to passively let the optician measure me, but rather to hold my head in my normal way. With the resulting glasses I could see great from the first moment. The brand, and the placement of the center ("seg height") is critical with progressives. So then is the way the frames are adjusted on your face. If that's off, then the lens position is off too. So if your frames get loose and slip down your nose even a millimeter, it'll change things.

I can read a book for hours with my progressives, but because a computer is at the distance where progressives have their narrowest field, they aren't really comfortable (or recommended) for extended use. I have a pair of single-vision glasses I keep by the computer.
