Cressi Quantum Dive Mask + Fitted Prescription Bi-Focal Lenses

Cressi Quantum Dive Mask + Fitted Prescription Bi-Focal Lenses, Fitted Optical Correction Lenses In Your Cressi Quantum Mask With Anti Fog System. The ultimate Cressi diving mask. The Quantum combines the raked lenses for maximum vision, evolved from the Big Eyes mask family, with Cressi Anti Fog technology and Cressi's Crystal Silicone, the ultimate diving mask. Simply choose your Quantum Mask and select the LH and RH prescription and we fit the bi-focal lenses and ship it to you ready to go! The Quantum uses Cressi Fog Stop Antifog technology (more below) to prevent warm moist exhaled air fogging the mask up. Despite the antifog system, heat exchangers and small radiators the quantum is still incredibly compact and offers superb visibility. The Quantum uses top quality materials like crystal silicone, incredibly transparent and long-lasting crystal silicone won't turn yellow with age. And thanks to its special chemical composition it drastically reduces the irritating effect of lens fogging. An absolute cressi exclusive. The low volume of the Quantum mask makes it equally suited to spearfishing, snorkelling and freediving as well as diving. The quantum also takes a range of bi-focal lenses ranging from +1.0 - +3.0 in 0.5 diopter increments as well as negative optical lenses.

Cressi Fog Stop Antifog Technology

The major innovation with the Quantum mask is that as well as offering enhanced downwards vision it avoids the fogging phenomenon through the internal thermoregulation of the warm, damp air exiting the nose. Exhaled air from the nose is channelled by a system of membranes set in the moulding around the eyes and nose and deviating the flow towards the  skirt rather than the lenses. The external part of the skirt features a cooling system composed of two small heat exchangers that act as radiators. The effect is that the temperature inside mask drops, coming closer to the external temperature and the droplets of humidity are trapped before the air reaches the lenses, preventing them from fogging up. Note: This is a customised product and therefore it is not eligible for standard returns. There is a handling charge of £40 to return this mask + P&P and the mask must be returned unused and with the original “plain” Lenses as well as the lens packaging.
