Exclusive benefits of SeaDive vision-enhancement lenses

For over seven years, SeaDive has developed and field-tested, anti-reflective (ARC) mask coatings on tempered glass. Standard tempered glass has at least a 4% rate of reflection which can distort underwater vision.  SeaDive’s ARC coatings allow almost 100% transmission of light to the diver’s eyes.  SeaDive has an exclusive application and laboratory fabrication process to create these unique mask coatings. 

RAYBLOCKER-HD

• RayBlocker-HD coatings allow almost 100% light passage which provides higher definition (HD) vision underwater.

• Light entering the lens is refined by Sharper Image Technology, a RayBlocker exclusive, for a brighter, sharper image.

• Reduces harmful UV rays and glare.

• Inside coating is a blue tint that reduces eye strain for very comfortable viewing.
