UV 420 LENS TREATMENT
UV 420 Lens Treatment protects against harmful high-energy visible (HEV) light and its potential to damage the Retina. 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.
