The ultimate in comfort and performance, the Big Eyes Evolution Crystal combines the best of Cressi technologies. 

Raked lenses, with Cressi’s inverted tear-drop shape, are placed close to the eyes for an exceptional field of view, and the Crystal Silicone skirt delivers excellent light transmission while resisting discoloration and fogging. 

The Crystal Silicone skirt also seals gently against the skin with a very open angle that accommodates a wide range of facial shapes. 

Graduated glasses for myopia from -1 to -6 dioptres (half by half).
