Without eyelashes, dust would invade eyeballs and people trying to get out of speeding tickets would have to bat their uvulas. Extend fluttering fringe with today's Groupon: for $17, you get Le Fling, a half set of eyelash extensions, at Noir Lash Lounge, valid at the Surrey location on Croydon Drive (a $35 value).

Focused exclusively on semipermanent lash extensions, Noir Lash Lounge lengthens eye fringe with more than 100 different varieties of extensions. For the Le Fling package, skillful staff members stud lids with a half set of extensions placed mainly toward the outer corners of the eye and then tapered in for natural-looking, subtly fuller eyelashes to enhance patrons' seductive winks and blinked Morse code messages. In about an hour, one of Noir's professional lash wranglers applies a nonirritating adhesive that bonds the extensions for two to eight mascara-free and flare-free weeks. Customers can also apply the value of this Groupon toward a full set of extensions ($65) or other service, such as eyelash bulletproofing or the LashDip, a gentle coating of mascara designed to eliminate clumping problems for up to six weeks ($125 upper, $45 lower).
