What are Atomic UltraClear Lenses?
Most of (if not all) the Atomic mask range are fitted with what they called UltraClear lenses which are made from an optical grade glass.
What's Wrong with normal lenses?
It's probably not something you've ever noticed before but standard glass used in most masks have a green tint to the glass. To see this tint, put your existing mask up to a piece of white paper or if you can see the lens from the side it is immediately obvious. The green tint is the result of iron impurities left over in lower quality “float” or window type glass. That green tint distorts true colours and some of the light that passes through the lens bounces off these impurities, preventing it from reaching your eyes.
What makes UltraClear so Special?
Atomic UltraClear is an optical quality glass with exceptional clarity and high light transmission, with no colour distortion. The exceptionally high light transmittance and lack of distortion in the UltraClear lens maximises the light available for improved visual acuity, especially underwater in low light conditions.
To give you some numbers to compare, standard float glass lets through approximately 86% of the available light but UltraClear lenses can allow up to 92% light transmittance. That may not sound like a great deal but it really is something you have to see to believe. Combine that with the increased colour vibrancy and clarity and you'll never want to dive with a standard lens again.
