I estimate I need another 3mm of available eye relief on these bins when using my specs with a 1mm thick O ring to protect them.
Could I add to each eyepiece a lens, presumably concave, to provide this and, if so, what strength should I buy taking into account the additional lens thickness?
I propose buying inexpensive plastic lenses to try first.
Thanks
