Intro: SCUBA Mask Wiper Blades
Cars are manufactured with windshield wipers for one simple reason: they help you see better in wet conditions. Given this fact, it makes perfect sense to take this concept to other areas of life.
I like to SCUBA dive, but I have always found the mask visually restrictive. So, it is completely logical to add wiper blades to the mask to improve the visibility.
