    Does anyone have experience with low volume masks and prescription ?

    I thought that if I buy a new mask I would rather have the ability to have a prescription.

    I read that you can either have prescription that you can stick on the glass or you can have specially made goggles.

    Not too sure what’s good, what’s bad and the pros/cons.

    Speaking from experience with my lab:

    Most prescriptions will have the lens bonded to the existing glass, even if the glass is removable. He can instead replace the glass for just a select few masks, at a higher cost.

    Some few very low profile masks may put the new glass so close to the face that fogging becomes an issue from body heat. (that is an issue for me on one mask) Higher corrections require glass that is thicker at the edges. High index lens (higher cost) will be slightly thinner, and may mitigate the fogging.

    All the above relates to correction for near-sighted, and bi-focals. If just gauge readers are required, there are simpler options. Some masks also offer "off the shelf" diopter replacement glass for near-sightedness, which is fine as long as bifocals and/or astigmatism correction is not needed.

    Aqualung Technika. Great mask, except for the extra effort keeping it fog free with the added glass.
    My customers frequently add an rx to the Cressi Big Eyes Evolution with no complaints, and that is also a great mask - my best seller.

    I bought the Dive Rite mask from DGX, it was too big for my face and leaked badly. I bought the DGX Ren Mask and it fits perfectly, does not leak, does not fog. It is available -1 to -8 diopters in 0.5 increments, separate for each eye. It is inexpensive, $50. The field of view is not as good as my Cressi masks. I may replace the DGX mask at some point, but it is perfectly fine.

    Sea Vision makes a mask with lenses ground to your prescription. No inserts. Their classic mask is 122 cc in volume. Debatable as to how low of volume is low enough. I'm quite happy with my Sea Vision mask.

    My wife ordered me a low volume prescription mask on amazon for about CAD60. It doesn't have any brand info on it, but it looks like it might be one of the "Scuba Choice" models. Originally I thought it was going to be my backup mask, but ended up liking it more than the higher volume one I picked up (and tried on) at a LDS.
