First light with contact lens!
Success! I now have a single multi-focal contact lens for my non-dominant left eye.
This allows normal viewing through the eyepiece with my dominant right eye, and reading of my Argo Navis and observing lists etc. with my left eye.
I've found that I can wear the contact lens all day without too many problems. I've effectively gone 'mono-focal', left eye for reading, computer time etc. and right eye for distance stuff and the scope eyepiece.
I don't think I will be able to do this full time as, for everyday use, my vision is slightly compromised for both distance and reading.
Despite the moon, I've had a couple of short viewing sessions and I'm very happy with the result.
I would recommend anyone who has issues with continually taking glasses off and putting them back on again, to have a session with their optometrist.
A big thank you to those who suggested the contacts!
Cheers
Chris
