dasalomon:
1) sticking something in my eyes if I don't have to. Dr's in general advise against it.
2) needing glasses to counter the lenses between dives
3) having to use the cover when asseding/descending to accomodate for the distortion
4) difficulty in clearing the max - larger volume to clear
I know the vision is supposed to be fantastic but it does seem like a lot of draw backs.

I just bought a HO mask - my vision is naturally +3.5, so I usually wear -3.5 contacts. With the HO, I can skip the contacts, and have perfect vision underwater (I played with it in the pool for about an hour last week). So I'm the opposite of you - however, I do have plenty of experience with contacts and glasses, so...
1) - contacts take a little getting used to, but once you do they're no big deal. Some of us poor myopians are stuck with them 16 hours a day our whole lives; as long as I take them out at night, my eyes feel fine. A few hours every now and then for diving will be annoying at first, but shouldn't screw up your eyeballs!
2) Yep, glasses are a pain. I actually plan on usually popping my lenses in and out between dives, because I hate glasses so much. (But, I've gotten really good at contact removal/replacement - you might indeed be stuck with glasses) We'll see how long I stick to that plan, though - glasses would definitely be simpler!
3) I wouldn't bother with the cover. +3 or 4 vision isn't so bad that you can't find a boat! I'll probably bring the monocle along in case I REALLY want to see something in that much detail, but unless you need to be able to read signs at a distance, it's no big deal.
4) This was my biggest concern with the mask - I HATE clearing; it's always been my weakest skill (sad, I know). I have to say, the hydrooptix mask was WAY, WAY easier to clear than my small-volume flat mask. Those two purge valves at the bottoms of the eyes? They actually work! It totally blew my mind; I could clear it twice on one breath, and with just the lightest tough to the top of my mask. Really cool.
I can't wait to get this thing in the actual ocean - I'll be reporting back on it next week; its virgin trip is July 5! I'm so excited I've actually been DREAMING about using the darn thing.
