Blue Light Blocking Glasses
Our blue light blocking glasses are designed to support your eyes and circadian rhythm from morning to night. Because different times of day call for different types of protection, each lens in our lineup — SOL (yellow lenses for daytime screen usage), ECLIPSE (amber lens for sunset), and LUNA (red lens for nighttime) — is purpose-built to match the natural light your body expects.
✔️ Promotes Melatonin Production
✔️ Blocks Blue & Green Light
✔️ Sleep Better
✔️ Protect Your Eyes
How Do Blue Light Blocking Glasses Work?
Blue and green wavelengths of light — especially those between about 400nm and 550nm — play a key role in regulating your circadian rhythm. During the day, these wavelengths of light help you feel awake, alert, and set your internal clock. After sunset, however, exposure to these same wavelengths can confuse your system by continuing to signal “daytime,” even when it’s dark outside.
Nighttime blue light blocking glasses work by filtering out this melatonin-disrupting range of light, helping reduce stimulation at a time when the body is naturally preparing for sleep.
Our nighttime blue light blocking glasses are designed to block 100% of blue and green light within the 400nm–550nm range, creating a calmer, low-stimulation visual environment that supports relaxation, recovery, and sleep readiness.
Our daytime yellow lenses work differently. They selectively reduce harsh, high-energy blue light while allowing the beneficial wavelengths your body needs during the day to pass through. This helps ease eye strain and visual fatigue without dulling clarity, focus, or daytime alertness.
The Benefits of Blue Light Blocking Glasses
High-quality blue light blocking glasses help by:
• Supporting natural melatonin production in the evening
• Encouraging deeper, more restorative sleep
• Reducing nighttime overstimulation from screens and indoor lighting
• Protecting your eyes from harsh spikes of artificial blue light
We always recommend starting with healthy lighting habits first — using warm incandescent light, red bulbs after dark, and turning off overhead lighting whenever possible. But even in a well-lit home, there are moments we can’t fully avoid modern light exposure.
Late-night grocery shopping, bright refrigerators, your neighbor's bright security lighting, televisions, laptops, and phones all emit stimulating blue light at times when your body is preparing for rest. Blue light blocking glasses act as a protective buffer during these unavoidable exposures, helping your system stay aligned with nighttime biology.
Supporting Your Body After Dark
The most effective way to reduce nighttime light exposure isn’t a single solution — it’s a gentle, layered approach that works with your body’s natural rhythm.
As evening arrives, we recommend gradually softening your environment rather than abruptly “cutting off” light.
Our evening ritual includes:
• Using warm, low-wattage incandescent lighting throughout the home
• Turning off overhead lights after sunset and relying on table and floor lamps instead
• Incorporating red light in the late evening and nighttime, when possible
• Wearing blue light blocking glasses when using screens or devices
This approach allows you to maintain a functional, modern life while still honoring your circadian biology. Lighting sets the foundation, and blue light blocking glasses act as a supportive layer — helping reduce overstimulation during those inevitable moments when complete light control isn’t realistic.
What are blue light blocking glasses?
Blue light blocking glasses are designed to filter specific wavelengths of visible light that strongly influence the body’s circadian rhythm. After sunset, exposure to blue and blue-green wavelengths can signal “daytime” to the brain and suppress the natural release of melatonin — the hormone that promotes sleepiness and helps initiate the body’s nighttime processes. By reducing these circadian-stimulating wavelengths in the evening, blue light blocking glasses help support melatonin release and create a more biologically appropriate light environment for winding down and preparing for sleep.
Do blue light blocking glasses improve sleep?
Reducing blue and green light exposure in the hours before bed makes it easier to wind down and fall asleep. Blue light blocking glasses are most effective when used alongside other supportive habits, such as dim lighting, warm incandescent bulbs, turning off overhead lights, and minimizing screen use before bedtime.
Which wavelengths should blue light blocking glasses filter for nighttime use?
Blue and green wavelengths of light between approximately 400nm and 550nm play the strongest role in circadian signaling. During the morning and daytime, this light is essential — it helps wake the body, promote alertness, and set our internal clock. After sunset, however, continued exposure to these same wavelengths can interfere with the body’s natural nighttime shift.
For evening and nighttime use, it’s important to reduce or eliminate light in this range. Glasses designed specifically for nighttime wear should filter the full 400nm–550nm spectrum to be truly effective. Our nighttime lenses are engineered to block 100% of light within this melatonin-disrupting zone, helping create a visual environment that supports relaxation and sleep readiness.
When should I wear blue light blocking glasses?
For nighttime support and optimal sleep, we recommend wearing blue light blocking glasses in the 2–3 hours before bed — especially when using screens or spending time in brightly lit environments. They can also be helpful during unavoidable evening exposures such as grocery shopping, travel, or watching television.
Are blue light blocking glasses necessary if I already use healthy lighting?
Healthy lighting is always the foundation. At night, we recommend warm, low-brightness incandescent lighting, red bulbs, and turning off overhead lights altogether.
Blue light blocking glasses are meant to be an added layer of protection during moments when you can’t fully control your environment — such as screen use or exposure to commercial LED lighting (late night grocery runs, travel, etc.)
What are the biggest sources of blue light at night?
If a light source appears visibly white, then there is blue light present. Common sources include device screens, televisions, LED lighting, fluorescent lighting, etc. Even brief exposure to these light sources at night can be surprisingly stimulating for some people.
Can I wear blue light blocking glasses all day?
Lenses designed to block the full 400nm–550nm range are intended for evening and nighttime use only. Wearing strong nighttime lenses during the day can interfere with natural alertness and visual clarity, which can make you very drowsy or tired. For daytime use, we recommend lenses that selectively filter harsh blue light while allowing beneficial wavelengths to pass through, like our daytime SOL yellow lenses for daytime blue light filtering.
Do blue light glasses really work?
Yes, especially red lens blue light blocking glasses like Luna, block the wavelengths of light responsible for suppressing melatonin, making them ideal for nighttime screen use and sleep protection.
