Photochromic lenses lighten in low light conditions to Cat 2 and darken to Cat 3 in full sunlight.
The San Juan high tech frame is moulded in three parts with the first two components sonic welded to create air cells before being placed back into the injection moulder where the sanaprene non-slip components are attached.
The San Juan, fitted with 1.1mm triacetate lenses has buoyancy of 0.95gm/ml while fresh water is 1.00gm/ml and salt water can vary between 1.03 and 1.05gm/ml, hence they will float in even the most turbulent water.
The high wrap frame gives great protection from the side, eliminating glare, wind and spray whilst offering great peripheral vision.
The San Juan frame is available in three colours:
Matt Black/Grey temples and nose piece
Matt Tortoiseshell/Tan temples and nose piece
Matt Grey/Red temples and nose piece
The lens options are grey or amber. Supplied with a soft neoprene case, cleaning cloth and leash.
