APEX Lens Technology is featured in 100% of HammerHead Spearguns dive masks. APEX Technology increases light transmission over standard tempered glass by over 13%. That means you should see 13% more lobsters, octopus, or fish!

APEX lenses are manufactured in a process that eliminates iron oxide impurities for 13% increase in light transmission over standard tempered glass. Advanced technical lens coatings are then applied to the APEX glass for the most extreme of dive applications.

The winning combination of the APEX glass and purple anti-reflective coating allows 98% of light transmittance. This technology offers unparalleled color perception, highly recommended for the deeper diver or underwater photographer.
