Message: <blockquote data-quote="matthew_" data-source="post: 3380881" data-attributes="member: 137083">Do all standard Maven B2s have 12 diopter pass infinity (i'm talking about negative diopter or nearsightedly because farsightedness would have opposite focus knob directions)? What other central focus binoculars have this extra reaches past infinity? About having your IPD checked. My  experience was that if you have it checked by the original optometrist/optician. He would doctor the result (marking the lens area wrong) and tell you the IPD is perfect (this is because he couldn't return it to the labs since most labs have 2mm tolerances). So what I did was bring it to any other optical stores to have it checked. And all the time I'd have accurate results of the exact IPD (which is wrong all the time).</blockquote>
