The Tusa Paragon S is a single lens version of the popular Paragon Mask which offers all the same great features of the original but with a reconfigured frame and lens design that is perfect for divers that don't need corrective lenses. The lens is still made from optical grade glass and is still treated with the same UV 420 and anti-reflective coatings.
The Tri-Mix frame comprises three layers to produce a single frame structure. A polyurethane (PuRiMaX) material provides bump protection whilst a cross-beam metal frame structure combined with a polycarbonate frame bolts together to create a seriously tough mask.
The Paragon S features Tusa's new Freedom Fit II skirt which builds upon the original version with additional strength and rigidity to make the mask more suitable for use in tough environments. The Freedom Fit skirt design uses a series of dimpled areas, varying silicone thicknesses and stability ridges to ensure the mask fits a wider range of face shapes in a more comfortable way.
As an additional level of personal protection the Paragon S uses UV 420 treated lenses that protect against harmful high-energy visible (HEV) light and its potential to damage the Retina. High-Energy Visible (HEV) light in the 400-420 part of the spectrum is known to cause cell death in the retina due to strong oxidative stress. HEV light is not just present on sunny days but overcast days as well. Therefore, it is extremely important to protect your eyes against UV and HEV light in all weather conditions when diving.
