Fitover Day Swannies by Swanwick have been designed with precise standards so you always get a secure, comfortable fit over the top of your existing prescription glasses. For those who already wear glasses, these fitover blue light blockers easily slip over and attach to your existing frames, relieving you of eye strain resulting from using digital devices.

How Classic Night Swannies® optimize your sleep for better performance
Swanwick has spent over six years testing and developing its lenses to give the best results for sleep optimization and wearing experience.
BLOCK MORE BLUE LIGHT THAN OTHER GLASSES
Most clear lens blue blockers block very little blue light over 420nm. Day Swannies block more blue light in the harmful part of the spectrum up to and over 450nm. Our full transmission reports are available on our website.
NO MORE HEADACHES
Prolonged exposure to blue light can cause unwanted headaches. Reduce Digital Eye Strain symptoms such as headaches by wearing Day Swannies during screen time.
BEST BLUE LIGHT BLOCKING TECHNOLOGY
Specially designed lens coatings are combined with proprietary lenses to block the right amount of blue light for daytime. Laboratory tested for effectiveness and quality.
Digital eye staring from working on screens for prolonged time can lower productivity over time. Day Swannies help you work smarter and longer by alleviating the effects of screen time, so you can continue to be productive all day, every day.
STOP FATIGUED EYES FROM SCREEN TIME
The flicker and glare from digital screens make your eyes work harder than normal. This causes eye fatigue and tiredness. Day Swannies counteract these negative effects caused by screen exposure, reducing eye fatigue.
UTILIZE THE GOOD BLUE LIGHT
Some blue light is good for you in the daytime. Your body relies on natural blue light to regulate circadian rhythm, and blue light can contribute to memory, cognitive function and alertness. Day Swannies allow natural levels of good blue light above 450nm to pass, so you don’t miss out on these benefits, while remaining protected.
What is the difference between Day and Night Swannies
Night Swannies (orange lens) block more than 99% of blue light between 400-500nm and are designed for wearing before bed time. This is because blue light from 450-480nm has been shown to prevent the body from naturally producing melatonin. At night time, blue light exposure should be limited as much as possible so that your body can get ready for sleep.
Day Swannies (clear lens) are designed specifically for wearing while using screens during the daytime. They block 45-98% of blue light in what studies have found to be the most harmful part of the blue light spectrum between 400-450nm.
Day Swannies allow a natural level of exposure between 450-500nm, giving your body the signals it needs to stay awake during the daytime and allow you to perform at your best.
A natural level of blue light during daytime boosts alertness, memory and brain function. Day Swannies afford these benefits while protecting against harmful rays from computer screens etc., which can lead to digital eye strain.
When you combine a healthy level of blue light during the day and limit your exposure to all blue light at night, this will help regulate your sleep/wake cycle to help you optimize both your sleep and waking hours.
So happy with the results! - Nancy D.
So happy with the results I bought 3 more pairs for my grandchildren since they all do distance learning.
Reduces eye strain - Karen M.
I love my Fitover Day Swannies! They fit perfectly over my prescription eyeglasses and they don't weigh down on them --I barely notice them. I spend several hours in front of a computer screen daily and I do notice a reduction in eye strain. I bought them specifically to protect the health of my eyes against the long term effects of blue light.
Them seem to be effective - Anne H.
Them seem to be effective, my eyes seem less tired.
Swannies Blue Light Glasses For Sleep
Too much exposure to harmful rays of high energy blue light from digital screens, light bulbs, led lighting, and other digital devices, can lead to tired eyes, headaches, blurry vision, and worse: It can disrupt sleep patterns ultimately leading to a whole host of other problems.
To optimize your sleep, Night Swannies blue light blocking glasses should be worn at least 1-2 hours before bedtime continuously. Blue light emitted from digital devices is all around. But when wearing Swannies, blue light filters through our proprietary lenses, meaning less blue light actually touches the receptors in your eyes.
For 1-2 hours (or more) before bedtime, try not to take them off at all until you haave turned off all lights and digital devices, and are already in bed ready to sleep. Even a small doze of blue light is too much if you're wanting to get quality sleep.
Some people find better results from wearing Swannies even earlier to filter blue light longer, and we encourage you to experiment to find what works for you. Everyone is different, and how much blue light you take in is largely determined by how much time you spend in front of a computer screen, looking at your phone or other digital devices, and whether the lights in your environment are designed to produce less blue light.
Swannies For Blue Light Protection
Night Swannies blue light blocking glasses can also be used during the day to protect your eyes from excessive blue light exposure. For example, when using digital devices for prolonged periods, you can wear Swannies blue light protection glasses to minimize eye strain, prevent headaches and digital eye fatigue.
We do not recommend you wear Night Swannies blue light glasses continuously the whole day.
Take regular breaks and allow some natural light exposure to ensure your body knows it's daytime. During the day, it's not good to block blue light to the degree that Night Swannies do continuously.
If you want extended protection during the daytime, we recommend our Day Swannies clear blue light glasses, which can be worn continuously, all day.
