My constant companion – Ultavid 10x25s were giving me eye strain. I have 2 pairs and one was performing perfectly. The second pair functioned well but I could never seem to get the diopter quite perfect and I often found I had to set it differently at different times. I continued to feel eye strain. It is not the kind of problem I could reproduce on demand.
I live a few miles from the Leica’s office in Allendale NJ so at lunch time I dropped in. They were taken in the back for 5 min and the tech came out and told they were replacing them. I walked out today with a new pair in the box etc. They are transferring the Passport coverage to the new pair
The Passport service was excellent!
Galileo would be very impressed with the optics we take for granted. His field of view was about about 15 inches at 100 yards."The telescope was the first extension of mans senses - It therefore helped shift authority in the observation of nature from men to instruments."

FYI
The BBC has a downloadable audio show on the history of optics. I clicked the download link to hear it. Galileo started with 3x then moved up to 8x and finally 20X in case you were wondering!
