Does 1.25 magnifier need a dioptre adjustment?

Robert, it would be harder to use with glasses but, not a lot harder than the 1.25. You mainly use it for longer lenses so, the 75 frame lines are well within your field of view with glasses. I'd try it.

 

You may also want to peruse refractive surgery options. Lasik or other refractive surgeries may not be your best choice but, you might be a good candidate for clear lens exchange.

 

After the procedure you would use no glasses with your Leica and with a high degree of probability you would prefer this option over glasses in general. Of course, you would still need reading glasses. GMB might also look into CLE.

 

It all becomes a bit of a compromise as we age but, there are options to help....

Rick,

 

Many thanks for your explanation. I have to try to figure out whether my two eyes really focus differently or whether I simply got it wrong with the reading glasses.

 

I don't think I am over corrected (went to a test recently). In fact, about a year ago, I got a stronger correction for both eyes, but for the left eye I went back to the old correction because I felt overcorrected.

 

BTW, the left eye is my dominant eye but I trained myself to also shoot with the right eye (amongst other reasons to avoid nose grease on the screen),

 

Again, many thanks for your extensive explanations. I may give the other maginfyer a try.

Rick, going off topic ... I was surprised that you recommend CLE as I thought that was only for cataracts etc. I have been considering Lasik but concerned that, as my prescription has been slowly changing over the last decade, the results would not be effective after two or three years.

 

Rather than tie up the forum with a non-M8 discussion, is there a source of good information on CLE and Lasik you could point me to?

 

Thanks

 

Robert

Rick, the virtual distance of the framelines and RF patch at 2m is the value given by Leica over the years. I have the impression that some people on this thread confuse the actual viewfinder image with the RF patch. These are two different images.

Robert... CLE is very viable and for someone who has virtually no accommodation and who has such a high prescription, it might be worth considering. I just finished the 1 week post-op on one of our peds doctors who had an Rx of about -8.00 and about -1.50 astigmatism. She has become increasingly contact lens intolerant. She is 47 and has thin corneas. She wasn't suitable for LASIK because of her thin corneas. So, she opted for CLE. She is very happy with the outcome.

 

I, on the other hand do very well with contact lenses and therefore will wait. So, you can see that it is important to seek counsel from someone who knows you and your case as there are so many things that need to be considered. This forum is not a place to be counseled but, information can be enlightening.

 

jaapv... I agree with you. I don't believe that the virtual distance of the frame lines places any accommodative burden on the visual system when focusing the range finder. Your eye is looking at the image. The image is what it is.

I did look into it. Lasik is, for the reasons you explained in your other threat, not an option. So far, I am ok with the contacts and the reading glasses. But one day, may be CLE is the better option.
