Cat Eye Day Swannies - Blue Light Blocking Glasses
| Delivery time for this product is approximately up to 20 working days |
Blue light blocking glasses for daytime use. Subtle cat-eye angles and a round frame are a sleek option for those with a fashionable flair.
Reduce digital eye strain
Day Swannies 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.
Day time glasses block blue light and ensure that you work (or play!) stress free. Anti Reflective and Anti Glare lens coating helps prevent Insomnia and Macular Degeneration
Need better sleep?
To optimise your sleep / wake cycle and get a great night's sleep, we recommend swapping to Night Swannies in the evening as they block the full spectrum of blue light.
Daytime Swannies Features
Cellulose Acetate Frames
A Natural BPA-free environmentally friendly alternative to petroleum based plastics. Strong, lightweight and flexible, can be shaped to your face for a perfect fit and be readjusted.
Spring Hinges
Spring hinges on Cat Eye Day Swannies provide a wide range of movement for extra comfort and durability.
CR-39 Lenses
Prescription-grade lenses and anti-reflective coatings for superior visual clarity and protection against blue light.
Control blue light exposure
The Cat Eye Day Swannies lens provides you with the perfect balance of protection against the most harmful part of the blue light spectrum (400-450nm), while letting in some of the healthy blue light (450-500nm), which helps regular circadian rhythm and improves alertness and memory function.
FDA Registered
Swanwick Sleep is fully registered with the Food and Drug Administration (FDA) and offers a one hundred percent money back guarantee for risk free purchasing.
Size Guide
The majority of adults find that the regular size fits best for them.
Compare the measurements to your current eyewear. The lens, bridge and temple widths are usually marked on the inside of the arm of the glasses
Acetate frames can be heated up and moulded for the perfect custom fit, or adjusted if bent out of shape. Most opticians or eyewear stores will do this for free.
