The Sherwood Ceto mask is a colored enhanced single lens frameless mask with a durable silicone over-mold. The Tangine lens or orange lens was designed to offer optical contrast while diving. The Tangine lens drastically reduces light wavelength from 400-600 nanometers. This minimizes the UV light entering the mask which reduces glare and improves optical clarity.The Rubicon lens or red lens was designed to add more optical contrast and make things easier to spot while diving. This lens is ideal for low light levels or even night diving. The magenta lens is designed for use in waters where colors are richer and more vibrant. 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.
