This magenta lens is designed for use in waters to see are more rich and vibrant colors. This unique product is designed to filter out blue wavelengths in the water, allowing your eyes to see the brilliant reds, oranges, yellows and green colors that are lost as a diver descends. For example, at a depth of 25 feet, red is no longer visible to the naked eye. At 75 feet, yellow looks greenish blue because the yellow light has been absorbed by the water. The Seavision© technology adjusts the color bands to allow users to actually see and enjoy the colors there in front of them at lower depths.
This yellow lens is for use in low light situations such as lakes, quarries, caves, rivers, and night dives. It helps to optimize available light and help improve vision at the same time.
