Last Updated on June 27, 2023 by Snorkel Ken

Need a prescription snorkel maskIt is important for us to see the underwater world clearly, so that, we can enjoy and appreciate its beauty when snorkeling. As our eyes are designed for an open-air environment, it cannot really focus in the under-water environment. Thus, we need to wear snorkel mask or goggles in order to create an air space for our eyes to view properly under the water. Make sure that your diving mask is a good snorkeling mask as well, which is equally important.

The prescription mask is recommended for the people with far or nearsightedness. Those people, who have a prescription of about -1 diopters, can view clearly with a normal mask, as when you view object through that mask, it will appear about twenty-five percent larger as a result of refraction of light. But if your eyesight is weaker, you should use a prescription mask. Generally manufactures offer lenses from -1.5 to -8. However, you should rather not expect the lenses to match your prescription perfectly. For example, generally if a person has a prescription of -3.25, there is a high chance that he will either get a -2.0 or a -2.5. Mostly these kind of minor differences do not become too much of a problem, as they offer a much better view compared to the ones with normal lenses. These masks come in different price ranges and designs.

  1. Hi Snorkel Ken,

    Would it be better to buy off Amazon? Or should I go to a store? I’m traveling to Kona in a few months. I snorkeled in Hanauma Bay a few years ago, completely couldn’t anything without my glasses, and I don’t want that to happen again. Do you suggest for me to buy one from Amazon? Or if there a store on Kona that you suggest?
