I'm not sure what reading contacts are and with you being an Optometrist, I'm not disputing your knowledge, however; to say No you can't dive with a pair of reading Rx contact lenses, IMHO isn't quite correct. I do it every dive.
If you see reasonably well in the distance while wearing Rx contact lenses for reading, then you are most likely hyperopic in one or both eyes and in fact your situation is an exception that I didnt think of when I made my post. In that scenario, the reading power of the contact lens is partially correcting (or slightly over correcting) a mild to moderate distance prescription in addition to helping with nearpoint vision- This is probably why your distance vision is reportedly not so good in general...even when not wearing the contacts.
Or..you are in your early to mid 40s and you require such a mild reading Rx that it has an insignificant effect on the distance vision.
Or.. you are using an underpowered reading Rx in the contacts that allows you to see larger numbers but it's not ideal for very fine print.
Or any combination of the above.
I probably should have said "In the vast majority of cases, people who wear reading Rx's will experience significant distance blur, however there are exceptions to this rule, such as in the case of uncorrected farsightedness (hyperopia) and with very mild reading prescriptions."
Thank you for bringing this error to my attention.
I dive with contacts all the time. One side is for close (computer) and the other for distance and they work great.

This is the monovision technique that I had mentioned in an earlier post on this thread.
Divers with no significant prescription for distance may need to use only one contact lens, corrected for reading.
