Classic Day & Night

  Regular
Lens Width 53 mm
Bridge 17 mm
Temple 140 mm
Width 137 mm
Lens Height 40 mm

The majority of adults find that the regular size is the best fit for them.

Compare the measurements to your current eyewear. The lens, bridge and temple widths are usually marked on the inside arm of the glasses.

Acetate frames can be heated up and molded for the perfect custom fit, or adjusted if bent out of shape. Most opticians or eyewear stores will do this for free.

How to wear Night Swannies for sleep

  • To optimize your sleep, Night Swannies should be worn at least 1-2 hours before bedtime continuously.
  • Try not to take them off at all until you have turned off all lights and devices and are already in bed ready to sleep.
  • Some people find better results from wearing them even earlier and we encourage you to experiment to find what works for you.

How to wear Night Swannies for blue light protection

  • Night Swannies can also be used during the day to protect your eyes from excessive blue light exposure, eg. when using digital devices for prolonged periods.
  • We do not recommend you wear Night Swannies continuously for the whole day.
  • If you want extended protection during the daytime, we recommend our Day Swannies collections, which can be worn continuously all day.

How to 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.

Why Swanwick?

Swanwick is the only brand of blue light blockers that have routinely sought third party validation. We've been studied by the University of Washington and the University of Indiana. We've been featured in a study by SleepScore Labs, and had research findings published in the Journal of Applied Psychology and Harvard Business Review.

There is no other brand on the market that has gone to the lengths we have to make the validation of our technology the backbone of our company. Talk is cheap in the blue light world. Why Swanwick? Because our actions speak way louder than their words.
