Optical Lens - Cressi Big Eyes Evolution / Crystal Mask

Vision correction lenses for the Cressi Big Eyes Evolution and Cressi Big Eyes Evolution Crystal Masks.

These lenses are designed for individuals who are NEAR SIGHTED:
That condition of the ocular refraction in which the posterior principal focus of the eye lies in front of the retinal plane, so that neutral light waves, entering the eye in a state of rest, instead of focusing on the retina, come to a focus before they reach it, are reversed, and fall on the retina in diffusion circles of plus waves.

The lenses are available in negative half dioptre increments from -1.0 to -6.0.

The lenses are NOT interchangeable (they fit in only the left or right frame). If you have a different prescription for each eye, it is necessary to specify which value is for the right or left eye.
