These Ray-Ban 3607 present a clean cut style. One that reminds us of the Original Ray-Ban styles. A rimless design strips back any distractions, allowing the focus to remain on the lens. This lens features the new tri-tone fade lens. This new gradient style starts as a dark color and slowly turns into a transparent lens. The frame itself is lightweight. Providing a light and comfortable fit. A desirable double bridge features on the flattering rectangle shape. Ray-Ban recommend not adding a prescription lens which is the only drawback to these unisex sunglasses.
