LINDBERG's AIR Titanium, STRIP Titanium, and ACETANIUM frames are stylish, unique, and unobtrusive. AIR frames are hypo-allergenic and simultaneously light, strong, flexible, and resilient. STRIP uses laser technology to cut the frame into any shape or thickness. Like the AIR, STRIP frames are free from screws, rivets or welds, and are available in a variety of colors and shapes. ACETANIUM rims and the temples are made from acetate, while titanium wire has been used for reinforcing the temples, bridge and lugs. Blink Optical carries a variety of LINDBERG frames and proudly displays this exclusive collection at our Lake Forest Illinois boutique.
