BLUESYNC LENSES

The World's First Performance Enhancing Eyewear

Traditional sunglasses reduce “good” blue light, weakening your circadian rhythm. BlueSync strengthens it, increasing energy, mood, motivation, focus, and performance — while protecting against the most harmful light (UVA/UVB/HEVL).

Frequently Asked Questions

What is the difference between Daylight and Sunset? Do I need both?

Our daylight lenses are precisely engineered to filter the most disruptive wavelengths of blue light during the day, preserving visual clarity while supporting eye health and hormonal balance.

Our sunset lenses are designed for evening wear, blocking 100% of blue light and most green light to support melatonin production, natural sleep cycles, and cellular regeneration.

While Daylight Lenses can provide some benefit in the evening, Sunset Lenses have a stronger effect on supporting sleep. Conversely, because Sunset Lenses block more light than necessary during the day, they can reduce visual clarity — making Daylight Lenses the better choice for daytime use. This is why we offer both lens types, each designed for its specific purpose.

Will these help me prevent eyestrain? 

Our Daylight lenses (with a subtle yellow tint) are purposefully designed to provide the most advanced protection from blue light emitted by screens and artificial lighting. They help reduce eyestrain, headaches, and fatigue, while also supporting balanced hormonal rhythms throughout the day. For those who spend extended hours in front of digital devices and prioritize maximum blue light protection, Daylight remains the optimal choice.

Can I wear them during the night?

Daylight Lenses can be worn at night. They continue to provide meaningful blue-light protection, supporting relaxation and sleep. 

Sunset Lenses, however, are specifically engineered for evening use and deliver deeper filtration to optimize rest and circadian balance.

Daylight Lenses are designed to filter blue light from screens and artificial lighting during the day but remain suitable in the evening when a lighter tint is preferred. Scenarios where Daylight Lenses may be appropriate at night include:

  • Eating late and wishing to perceive natural colors while reducing blue light exposure.
  • Evening social settings where a brighter appearance is desirable alongside protection.
  • Nighttime driving requiring visual clarity with blue-light reduction.
  • Gradually transitioning to Sunset Lenses.

For optimal evening support, Sunset Lenses are recommended, as they maximize circadian regulation, sleep quality, and relaxation. They may also be worn during the day in specific situations, such as:

  • Working under harsh artificial lighting (e.g., hospitals or offices).
  • Exposure to intense sunlight when additional short-wavelength protection is desired.

Together, Daylight and Sunset Lenses provide a complete blue-light management system—supporting energized days and restorative nights.

What wavelengths do your Daylight lenses block?

Daylight Lenses have a hard cut-off at approximately 465 nm, with transmission increasing rapidly above that point. Designed for daytime use, they specifically address retinal health. The wavelengths most associated with retinal stress and oxidative damage peak around 430–440 nm and extend on either side. By fully filtering this range, Daylight Lenses reduce blue light exposure by roughly 95%, significantly minimizing unnatural hormonal stimulation from modern blue-enriched lighting.

What is Blue Light?

Blue Light is a part of the light we see every day — from sunlight to light bulbs, car headlights, and screens.

What is Blue Light?

Blue Light from the sun is the signal that sets our body clock ("circadian rhythm"), which regulates nearly everything in our body—sleeping, waking, hormones, neurotransmitters, digestion, energy, growth, recovery, and more.

Blue Light is a kind of "short-wavelength light" (along with UV)—the part of sunlight that contains a high amount of energy. Too much short-wavelength light can damage our eyes and skin.

Modern artificial lights and screens emit large amounts of Blue Light.

DAYTIME: high exposure in our eyes and causes unnatural constant stimulation of stress hormones.

NIGHTTIME: because the brain can't tell the difference between sun and man-made Blue Light, it tricks the body into thinking it's still daytime, blocking the natural wind-down, sleep, and repair processes. And since sleep is essential, this disruption can have massive consequences on our health.

Why do we need to filter blue light?

Our eyes and skin evolved under jungle canopies, where leaves naturally filtered much of the harmful blue and UV light.

We can tolerate some blue light. But constant, unbalanced exposure is harmful. For most of human history, we limited excess sunlight naturally—seeking shade, wearing clothing, and living in harmony with the day-night cycle.

Modern artificial lighting and screens are different. They emit large amounts of blue light—without the balancing, longer wavelengths of sunlight that protect and heal.

That's why today, especially for our eyes—the body's most light-sensitive organ—filtering blue light is essential.

Why do Blue Light Glasses exist?

Why do Blue Light Glasses exist?

Traditional sunglasses and optical glasses do not filter a meaningful amount of harmful blue light. Blue Light Glasses are a simple and effective tool to filter harmful blue light in both indoor and outdoor environments.

There are Blue Light Glasses designed for:

  • Daytime use, indoors: Daylight Lenses
  • Daytime use, outdoors: BlueSync
  • Evening use, indoors and outdoors: Sunset Lenses
