THE BLUE LIGHT BLOCKING GLASSES CHOSEN BY LEADING HEALTH AND WELLNESS EXPERTS FOR DAYTIME DIGITAL EYE STRAIN PROTECTION.

Swanwick's Crystal Day Swannies are tough to beat on the fashion front! These Day Swannies remain at the top of the bestsellers list month after month. You'll block the bad blue light from phones, tablets, and computers while attracting compliments like never before. You’ll find most clear-lens blue blockers on the market only block blue light up to 420nm. Day Swannies, however, block 98% of blue light at 400 nanometers, graduating to 45% at 450nm, and 21-45% of blue light between 450-500nm. This blend of blue light blocking ensures you the optimal conditions for performing your best all day long.

• Protects against symptoms of digital eye strain and computer vision syndrome.
• Allows a natural level of blue light exposure needed for optimal productivity during the day.
• Work longer without tiredness or eye fatigue.
• Block the most harmful wavelengths of the blue light spectrum found between 400-450nm.

PRODUCT HIGHLIGHTS

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.

OPTIMIZED PRODUCTIVITY

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.
