Another first for Cressi in the field of masks. Ocean Eyes, extensively covered by patents, takes advantage of all the most concepts introduced in advance by the Cressi masks: raked, inverted drop lenses, very small inner volume, extremely good downward vision and fantastic comfort. Furthermore, Ocean Eyes incorporates a brand new quick-release dismantling system for the lenses, which can be replaced with prescription lenses to correct visual defects. You only need a few moments and three simple operations to assemble your tailored prescription lens mask. The adjustment buckles on the strap are attached to the frame with a new (and patented) part made from flexible elastomer, which prevents the buckles or the actual frame from breaking so you can adjust the strap instantly with just a simple pressure from a finger. This system also prevents the skirt from being deformed, a possibility on models that incorporate the strap buckle in the actual skirt. Another pleasant addition is the possibility of instantly replacing the whole strap and buckle combination for rapid on-the-spot replacement, or to choose your favourite colour combination.
