Why does a flat mask make things look fuzzy around the edges?
A Chromatic aberration, also called color fringing, is when light breaks-up into its constituent colors (just like a prism!). To observe this using a FLAT mask, hop into a clean pool and look straight on at two stationary markings that are high contrast (i.e. a black tile on a white background). You’ll notice that the tiles appear very sharp and in focus. Now, rotate your nose away so that you are looking at the same markings at an angle through the lens. You’ll notice that one edge of the darker object is not only out of focus but fringed in orange / red! The opposite side of the darker object is fringed in blue / violet. That is chromatic aberration. In murky ocean water, you may not see the colors… but things do look fuzzy. By contrast, HydroOptix masks deliver razor-sharp vision, no matter which direction you look. So while a flat mask gives you a slightly enlarged (therefore sharper) view in that narrow cone where you point your nose, your overall vision is 10 times worse than M
