barry surely you cannot have a pd greater than 84mm?
i have been a dispensing optician for thirty years and i have seen 76mm max!

Pat
measured at 83 last set of specs, the majority of binoculars only give vision through one eye. Low percentile I know.

was it not set at 83mm for prismatic purposes eg. base in prism barry?
83mm is hard to believe mate, cheezes!

My IPD is 75mm - I know your pain!!! I find it near impossible to use binoculars (so don't), and light microscopes at work are a constant drama (usually have to go mono). Getting glasses for the first time was a real exercise in frustration, for me and the optician.

75mm is very wide lewis, deffo at the upper limit of my experience............but we are talking about nearly another centimetre!
the only times i have seen optical centres that wide was to induce prism by decentration if the optical presription had sufficuent dioptres to achieve it in a stock lens

i must say barry i am intrigued!!
