CliC magnetic readers are a new advance in eyewear with substantial improvements over the traditional solution to reading only glasses. The most innovative feature is the patented magnetic closure. This allows CliC readers to use a combined adjustable headband and neck strap which means not only do CliC readers stay in place while you are wearing them but also hang comfortably when not in use. You will never misplace your readers again! Other features include: Rugged, lightweight construction for ergonomic and long durability. Available in strengths +1.25 to +3.0. Available in Black (with regular or longer sized retainer), Dark Tortoise, Light Tortoise or Clear colors.
