If you're having trouble accepting the end of summer and/or your astigmatism, make room in your schedule for Sama Eyewear's Back-To-School event. This Saturday, Sama will host an all-day sale at its WeHo shop, during which their smart and trendy prescription frames will take an unprecedented nose-dive in price. Snag a pair of tortoiseshell or vintage-inspired specs for 50% off retail (read: just $75 each). What's more? A portion of the day's sales will go to benefit the Sam Vance Foundation, an organization dedicated to drug preventing among teens and young adults.
