Tech Tip

Why Black Skirt Diving and Snorkelling Masks Are Better

Clear silicone skirts on diving and snorkelling masks are popular because they minimise the claustrophobic feeling some people get when they wear a mask. Nevertheless, clear skirts actually interfere with vision. Extraneous light entering through the clear skirt makes it more difficult for the eye to focus and causes reflections that obscure vision. Demonstrate this by looking out a window from a lighted room at twilight. You will see better by cupping your hands around your eyes as you press your face to the window. For these reasons, knowledgeable divers and snorkellers seeking the best possible vision prefer masks with black silicone skirts.
