Wisp Blue Light Glasses - Slim Oval Blue Light Glasses for Women and Men This chic, slim oval silhouette makes a comeback with a retro feel of sophistication, in Black, Green and Tortoise. Wearable by women and men, the unisex design offers lightweight versatility for the screen-heavy parts of the day. The lenses have no magnification. Wisp is a zero-strength blue light pair for monitors, laptops and phones: the lenses filter high-energy visible (HEV) light from screens, and spring hinges give the slim frame a comfortable, flexible fit. A classic silhouette that looks at home at the office or on the sofa.
