I got a set of the SeaVision 2100 masks (all 3 color lenses), all with their gauge reader lenses. I could not be happier with the performance. Bonus: They accepted my HSA debit card for payment, so I had no out of pocket cost!

I was diving with an Atomic Frameless (2? I can't remember) mask. I always had a slow leak, which I just chalked up to having a mustache (even though I would trim it really, REALLY short before diving). This, after trying on a BUNCH of masks at my LDS and determining that the Atomic gave the best seal of them all. I would now recommend to anyone trying on masks that they do so with a snorkel or regulator in their mouth as I believe it changes the shape of your face and CAN affect how a mask seals. But I digress...
I went to Hawaii in March and my dive buddy had SeaVision 2100 masks. He got me to try his so I could see how cool the magenta lens is, in blue water, and how the gauge reader lenses worked. I loved the magenta lens. The gauge reader lenses worked great for me. And I happened to eventually notice that I was having no leaks. Nice! I went back to my Atomic mask for the second dive of that day and was right back to clearing my mask every few minutes.
So, I ordered my own SeaVisions as soon as I got home. I've now got about 15 or so dives on them and still think they are the bee's knees.
I also really like that you can order the SeaVision masks with either a clear or black skirt and your choice of colors for the trim. They make each mask to order. That does mean you need to be prepared to order and wait at least 2 weeks before you receive your order. With so many options, I went for black on black! LOL
As a less expensive alternative, I was using $15 HydroTac stick-on reader lenses form Walmart in my Atomic mask. They also worked fine. They even have the benefit of getting whatever power you want. +1.5, +1.75, +2.0, etc.. The SV gauge readers are only offered in +2.0, I believe.

I followed the instructions and info I found here on SB and put mine on and let them dry for a couple of days before I went diving with them and they stayed on through all 10 dives that I used them for, before I got the SeaVision masks. I think the HydroTacs are an excellent option for anyone who needs readers and already has a mask that works well for them otherwise. And I think they may be the only option for frameless masks (vs subframe masks).
HydroTac does have a scuba-specific version of their lens. From what I could tell, they cost twice as much and the only difference is that they are a little bigger. The regular $15 ones have been plenty big enough for me. I don't think I'd really want bigger ones.
I also put a set of the HydroTac lens on the inside of my regular sunglass lenses - which are quite curved. They have been on there for over 4 months now. One did pop off, once, but it came off when my glasses were laying on my desk, so I found it immediately and put it right back on and it has been secure ever since. Fortunately, you can see when air is getting under the HydroTacs and they are getting near to coming off. They get a LOT of air under them before they come off. And the air under them is not noticeable when you are wearing them. You only see it when you take the glasses (or mask) off and look at them. When that happens, you can just put your glasses in some water, then squeeze the air (as much as you can) out from under the HydroTac and let them dry again and you're back to good. I have done this once with the ones on my sunglasses.
