BRT, I haven't gotten any fogging during a dive or after. Are you doing cold water dives or warm? I wonder if that might be a factor.
I do sometimes get fogging when the lens is a bit dirty but a good cleaning helps. I use the peroxide bubbly thing every day and once or so a week I use the liquid rub cleaner and conditioner. I also use "Blink" drops that help remove protein deposits during the day because I seem to have lots of protein trying to build up.
If you have these you know about them. If not, you probably don't know much about them but probably wouldn't be reading this anyway so I'll not go into what they are, just why I have them and my diving experience with them.
Typically these are used for folks with Keratoconus which is not me. My issue is that my corneas are hopelessly buggered up with scar tissue from old refractive surgeries. (I do not know if Keratoconus in contraindicative for diving or not, so I can't give advice on that.) My vision fluctuates greatly during the day and the scars result in halos and stars of glare as well as seing several ghost images of whatever I look at. At night it was much worse. Neither glasses nor regular contacts gave me reliably useful vision, and that lead me to sclerals.
While I was getting fitted I searched for good advice on whether I could dive or not wth these. Since there is basically no exchange of fluid/tears behind the contact I didn't know if there might be pressure issues or not with descent and/or ascent and if I would experience discomfort and/or changes in vision as a result.
The results of my search were mixed and not very encouraging. I was getting fit for a just-released type called Ampleye by Art Optical and the company didn't offer much help either way since they are not diving experts. My optometrist isn't a diver either. He didn't see a problem diving but wasn't sure.
I called DAN which I should have done first.
Ther guy on the phone knew instantly what I was talking about. He said there was absolutely no reason in my case that I could not dive with them. So I went to Grand Cayman and did so.
I found no noticeable changes in vision during the dives, nor did I feel any pressure or discomfort. With old smaller hard or soft contacts there is a fear of losing a lens if you flood your mask. I do not think this is a concern with sclerals since, at least in my case, they are pretty well suctioned on. As hard as they come out sometimes, I'm sure they won't wash out!
So, my experience was very positive. I hope this helps others out and, of course, if you have any doubts call DAN!
Cheers,
DS
