Long eyelashes serve multiple purposes, from shooing incoming moths to extinguishing nearby forest fires with a single fierce blink. Elongate eye fringe with today's Groupon: for $49, you get a set of eyelash extensions, which includes 20 lashes per eye, at The iLash Factory (a $125 value).

The iLash Factory's professionals apply thick, natural-looking lashes to clients' eye flaps to allow for elongated winks. In no more than an hour, the fringe-extending specialists will glue 20 lashes one by one to the lashes subjects are currently wearing. The newly thickened lashes will dazzle onlookers and infuriate Bambi for approximately two to three weeks, safely staying put whether eyelash owners are sleeping, showering, exercising, or blinking out messages to bridge partners. Natural lash cycles vary, and The iLash Factory recommends occasional touchups when eyelashes fall out naturally. Clients can also upgrade to applications that include more lashes per eye if they pay the difference between the upgraded service and the value of this Groupon.
