Costa Tuna Alley
Tuna Alley offers a large, wrap-around fit to protect against outside glare, says Costa. It features front frame vents to alleviate lens fogging, as well as a no-slip interior lining to keep the sunglasses comfortably in place all day. Tuna Alley is available in tortoise, matte black, white, crystal and the new blackout frame colours, in the full spectrum of patented Costa 580 lenses.
All Costa sunglasses are 100% polarised and protect against harmful UVA and UVB rays. Its patented 580 lens technology offers ‘unparalleled’ polarisation and ‘razor sharp’ clarity by blocking yellow light at the 580 nanometer from entering the eye. Costa’s 580 lenses are available in optically-ground glass (580G) or super lightweight, impact resistant polycarbonate (580P). Lens colours include grey, copper, amber, sunrise, and blue, green and silver mirror.
