If you're having trouble finding the perfect pair of shades for summer, make room in your schedule for Sama Eyewear's super eyewear sale. On Saturday, Sama will host an all-day sale at both store locations (Beverly Hills and Sunset Plaza) 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 75% off retail (read: just $85 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.
