Description

Protect your eyes in style with these Swanwick® Crystal Day Swannies. These are blue light blocking glasses that can be worn all day, every day. Wear them whenever you are using digital devices to protect your eyes against harmful blue light and eliminate the symptoms of digital eye strain, including dry, sore eyes and headaches. With CR-39 lenses, Crystal Day Swannies provides you with the perfect balance of protection. While it blocks harmful blue light, it still lets some of the healthy blue light (450-500nm) in to help for regular circadian rhythm and improved alertness and memory function. These glasses come with cellulose acetate frames, making them adjustable, strong, and lightweight.

  • CR-39 lenses & anti-reflective coating for superior visual clarity and protection against blue light
  • Spring hinges provide a wide range of movement for extra comfort & durability
  • Lets in some of the healthy blue light (450-500nm)
  • Natural, BPA-free material, adjustable, strong & lightweight
Day Swannies are not designed to help with sleep. When the sun goes down, it is recommended that you switch to Night Swannies which block the full spectrum of blue light, to optimize your sleep/wake cycle and get a great night's sleep.
