custom prescription mask

I'm leaning toward one of those 'large window, close to face' designs, without side windows. I do like the idea of better vertical vision as well, since it helps to look down right in front of me at obstructions in my gear, probably make it easier to clip the rig to my BCD, etc.

I was looking at the Aqua Lung Mythos, but then I saw a lot of reviews saying the frame was fragile and broke easily.

Then I started looking at various Tusa models. Hard to pick a mask over the internet without ever trying it on.

=> never order a mask via internet. It needs to fit and you can only test it out in presence...

Incidentally, the prescription masks I'm looking at do not use inserts or glue-in panels, but instead actually grind the lenses into the mask glass itself. Supposed to be best for vision.

=> The masks with available and exchangeable optical lenses are just with a single fixed refractive power in (I guess) 0.5 dioptries increments. When you have special needs as additional astigmatism or varifocal lenses to correct for presbyopia (=you cannot read the numbers on your diving computer and/or how much bar are left from the finnimeter any more, because you eyes became old). Then you cannot use these simple optical masks any more, just because these pre-prepared lenses do not correct for astigmatism and have only a single, fixed, refractive power (e.g. -3 dioptries allover).

Then the masks with glued in lenses come into the play, since you can have any type of lens that you also would have on your regular over-water spectacles . They can be glued into any mask model, but because they are expensive this should be only a mask that fits to your face perfectly...

The standard masks with exchangeable optical lenses (e.g.: look2) are by far not the best for vision, as, as an additional problem, they do not account for individual pupil distance and if this is, by chance, extraordinary large or small, your vision is not perfect and is exhausting. They are just a simple and cheap solution for (mostly younger) people that do not need astigmatism corrected, nor have presbyopia (=need for better near vision to read dive computer or information on the camera screen/evf)...
