Prescription Blue Light Blocking Glasses — Tailored to You
Choose almost-clear Focus lenses to support productivity, reduce digital eye strain, and stay comfortable during long screen hours. Transition into Relax lenses, designed with a soft yellow tint to ease visual stress and support a natural wind-down in the late afternoon and evening. For nighttime, switch to amber Sleep lenses, which block 99% of stimulating blue light to help improve sleep quality and duration.

  • Custom prescriptions: Single-vision (distant, computer, reading), and progressive lenses made to your exact prescription.

  • Premium lens materials: Choose from CR-39, Trivex H53, or High-Index 1.67 for exceptional clarity, durability, and lightweight comfort.

Proven Results

An independent study by SleepScore Labs showed that Sleep Swannies (formerly Night Swannies) blue light blocking glasses resulted in significantly improved sleep, including an average of 33% increased sleepiness at bedtime, 11 minutes less time to fall asleep, and 24 minutes of reduced time awake during the night.

Classic Swannies

  Small Regular Large
Lens Width 50 mm 53 mm 55 mm
Bridge 17 mm 17 mm 17 mm
Temple 140 mm 140 mm 150 mm
Width 127 mm 137 mm 142 mm
Lens Height 38 mm 40 mm 44 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 Sleep Swannies for better rest

  • To optimize your sleep, Sleep 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 Sleep Swannies for blue light protection

  • Sleep 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 Sleep Swannies continuously for the whole day.
  • If you want extended protection during the daytime, we recommend our Focus Swannies collections, which can be worn continuously all day.

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.
