Retina Big Clarity introduces a new level of optical performance thanks to unique lenses produced in collaboration with industry leaders, Carl Zeiss. Clarity lenses have been developed with specific and highly advanced tints designed to enhance vision by increasing contrast and light. Unique Spektris mirror coatings have been engineered to complement each clarity lens base tint and are applied for three distinct weather conditions: sunny; partly sunny and overcast. POCs super-sized Retina Big has a huge field of view to increase reaction speeds. The double lens is made of optical grade PC/CP and has the best anti-fog and anti-scratch treatment available to promote vision and resistance. The PU frame conforms to different face shapes and maintains its flexibility even in cold temperatures, and the triple layer face foam and fleece ensures a comfortable fit.
