Julbo kept its design for the Access Sunglasses simple for versatility in the outdoors so you don't need to get different pairs for hiking, climbing, boating, camping, and casually cruising around town. This pair comes with the durable Spectron 3 lenses that shade your eyes in super sunny conditions, and you can switch them out with the included Spectron 1 lenses for low light conditions like bike riding in the early mornings or late evenings. Julbo added a flash finish to the Spectron 3 lenses in order to improve the filtration of visible light by producing a mirror on the exterior side. The Access's grilamid frame is lightweight and flexible in order to conform to your face for a precise fit. And an eight base curvature offers extra coverage from the sun's harmful rays so you can tune in on the fun you're having instead of annoyingly squinting at the sights.
