See the sea the way it was meant to be seen with the SeaDive Eagleye Rayblocker HD Purge Mask. Enjoy flood-free dives thanks to the nose purge - it helps keep the inside of your dive mask dry. The Seadive Eagleye HD Snorkel Mask features RayBlocker-HD tempered glass lenses for clear, glare-free vision above and below the waves. Most scuba masks come with tempered glass lenses nowadays, but only the Seadive Eagleye Rayblocker HD Purge Scuba Mask treats that tempered glass with a special RayBlocker-HD treatment that blocks out harmful UV rays as well as the glare and distortion other masks let through. This improves visual clarity in bright environments and also reduces the time it takes your eyes to adjust as you go above or below the surface. The anti-fog design also features a patented nose purge to help clear out any water that leaks in, and there is an easily adjusted buckle on the mask skirt to make getting the perfect fit simple. The transition from below the surface to above can be a challenging adjustment for the eyes, but the Seadive Eagleye HD Mask features RayBlocker-HD lenses that block harmful UV rays while also easing the transition by limiting glare and reducing surface grit. Designed to resist fogging in any water temperature Nose purge makes it easy to clear mask Tempered Glass Construction for improved durability and safety RayBlocker-HD Lenses reduce glare and surface grit Protection against harmful UV rays Quicker vision-return upon surfacing Easy-adjust buckle makes getting the correct fit easy
