Switch Vision Cortina Full Stop $249; switchvision.com
Heady Info: Switch Vision is a new player in the sunglasses arena, with a background in prescription optics, but this debut is all the buzz in our office. The frames have hidden magnetic strips, allowing you to switch (get the brand name now?) to three types of lenses when the light changes.
In Our View: The idea of switching lenses sounded gimmicky. But when a low bank of clouds settled over the water, I pulled off the 90 percent light-blocking lenses and snapped in the low-light ambers — a half-minute pit stop. The benefit was immediate, allowing a clearer look at the gauges than with full-tint lenses. Caveat: You have to commit a pocket to the extra lenses.
