RetroVision Sunnies Takes Shades Literally

The appropriately titled RetroVision is a pair of sunglasses which eschews tinted lenses for, well, shades. The eyepieces are filled with tiny, Venetian blind-style slats which cut out light. The slats should also restrict light from above and below, which means less glare from the sun and its reflected light. The concept design, from Sang Jang Lee, features pop-in screens for customization. I remember a similar product back in the 80s, although it came in cheap, brightly colored plastic and did little more than blind you with its four or five oversized slats.
