More Blue Light = Less Melatonin
Melatonin, a powerful antioxidant, plays many important roles in the body from regulating sleep to reducing inflammation and supporting the immune system. Artificial blue light disrupts our body’s natural production of melatonin at night by up to 60%. This leads to sleep disruption and mitochondrial damage.
All light is naturally balanced across a full spectrum in nature, however man-made sources of modern lighting and LED screen devices emit intense, unbalanced doses of an artificial blue light spike on our eyes. This un-natural spike disrupts our health, and importantly --our natural Circadian Rhythm which allows our bodies to sleep and heal.
This can lead to damaging effects on our overall health and wellness. Protecting your eyes is important but most blue light blocking glasses are made with near-clear lenses that fail to block the full blue light spike.
Melatonin Suppression and Mitochondrial Repair
Light enters the eye and stimulates specialized retinal cells, which convert it into an electrochemical signal. This signal travels along a multi-synaptic pathway through the brain’s circadian clock in the hypothalamus before reaching the pineal gland, where it regulates melatonin production.
A primary function of melatonin is repairing mitochondrial DNA. The damaging blue light spike measured at 455nm suppresses melatonin production. The lack of repair from this suppression leads to an accelerated accumulation of mitochondrial DNA mutations, known as “herteroplasmy.”
As mitochondrial DNA mutations increase, our body systems begin to lack the energy necessary to carry out their functions, leading to many modern chronic diseases.
The wavelength makes a difference
Visible light travels in waves. Our eyes can see wavelengths of light between approx. 400-750 nanometers (nm). Sunlight provides a broad, gentle wave of light to our eyes and can be healing to us and our daily circadian rhythm.
LED lighting and technology screens emit a sharp spike of blue light at 455 nm. Unlike the balanced mix of red and infrared that has always accompanied blue light outdoors throughout human history, this unbalanced spike is highly disruptive and has the greatest impact on melatonin suppression.
Clear lenses may only filter or block from 400nm - 420nm, providing no protection in the most damaging blue light hazard range of 435nm - 475nm, you need a yellow lens to block blue.
Not all yellow lenses are created equal. Lighter shades of yellow still allow much of the blue light hazard to pass through, leaving the brain exposed to the same disruptive signals. Our lenses are made as melanin-infused yellow lenses, giving consistent and complete protection against the full blue light hazard. This means your eyes and brain are actually shielded in the way nature intended.
Complete Protection
Leading clear lens
Leading clear and near clear lenses have little to no effect on the light spectrum above 420nm where it matters most. They simply do not block the light we most need protection from when using screens and devices.
Yellow day lens
Our daytime yellow lenses block 100% of the damaging artificial Blue Light Hazard from 435nm - 475nm as measured across the light spectrum. Our nighttime orange lenses go a step further to block all blue and green light up to 550nm signalling to the brain it’s time to wind down.
Melanin is the natural pigment found in our hair, skin, and eyes. It provides the body with powerful protection against ultraviolet and visible light, by controlling how the light is absorbed. Our bodies use melanin to take in light evenly and smoothly across a balanced, broad spectral range of visible light, from 380 nm to 700 nm.
What Melanin Does?
Melanin naturally absorbs the higher energy light (UV, violet, blue) more strongly than the lower energy light (yellow, orange red) to maintain a balance in our bodies (Blue is energizing, Red is healing, for example).
Melanin also provides near optimum protection to the retina by filtering the different colors of the visible light spectrum in proportion to their ability to damage tissue of the retina.
Support Your Brain, Hormones, and Sleep with Natural Melanin Lens Technology
We utilize a Patented Process using Melanin pigments built directly into the BioSpectral Optical lenses. These lenses help block + protect your eyes BETTER, while allowing you to see all the other colors more clearly.
Compared to other lenses that filter the same amount of light using other means of filtration, melanin lens wearers are able to more accurately differentiate between color hues and scored better on the Farnsworth-Munsell 100 Hue test (a measure for color-blindness) as this lens technology closely mimics that of our eyes natural filtration.
Melanin is a natural material shaped by nature over millions of years. It has been refined through evolution to absorb and manage light with incredible precision. Our lenses are designed to harness that same power, allowing you to benefit from what nature has already proven to work.
FAQs
Do your glasses block all harmful blue light?
Yes. Our yellow lenses block 100 percent of harmful blue light, especially the spike at 455 nanometers from screens and LED bulbs. Our orange lenses go further by also blocking green light up to 550 nanometers.
How to Use Blue Light Blocking Glasses?
Our BioSpectral lenses are designed to protect your brain, eyes, and sleep by optimizing light exposure throughout the day and night. Use them based on the time of day and your environment:
Yellow Lenses (Daytime Artificial Light Exposure)
Wear during daylight hours indoors when exposed to artificial light sources such as:
- Screens (phones, computers, tablets)
- Overhead LED lights
- Fluorescent or cool white lighting
- Screen-heavy environments like offices, schools, or airports
Yellow lenses block 100 percent of the most melatonin-suppressive blue light between 435 and 465 nanometers, supporting focus, mood, and natural energy.
Orange/Red Lenses (After Sunset Use)
Wear after the sun sets or when the blue hue fades from the sky. These lenses are designed for:
- Evenings at home
- Watching TV
- Working on screens after dark
- Using LED lighting in the evening
They block 100 percent of both blue and green light up to 550 nanometers, which are the primary wavelengths that suppress melatonin and overstimulate your nervous system at night.
This helps you:
- Fall asleep faster
- Enter deeper, restorative sleep
- Protect your endocrine system and mitochondrial health
- Enhance overnight healing and hormone regulation
Tip for new users: If you're new to blue light lenses, begin by wearing yellow lenses during the day and night for 1 to 2 weeks to help your visual system adjust before using red/orange lenses at night.
Can I wear them outdoors during the day?
We do not recommend wearing our lenses outdoors in natural daylight. Your eyes need full-spectrum sunlight to regulate hormones, support healthy vision, and maintain circadian alignment. Our lenses are specifically designed for use in artificial light environments. If you already spend a lot of time outside and want to enhance natural red light therapy, you may choose to wear the orange lenses outdoors for short sessions of 10 to 20 minutes. However, as a general rule, you should avoid filtering the full spectrum of natural sunlight, as it provides essential signals for overall health.
What makes BioSpectral different from other Blue Light glasses?
Most clear or lightly tinted “blue light blockers” only filter light up to around 430 nanometers, missing the most biologically disruptive part of the spectrum. Even many yellow lenses on the market only block up to 450 nanometers, allowing key portions of the blue light hazard to reach your eyes.
BioSpectral lenses are infused with natural melanin — the same pigment found in your eyes and brain — and are engineered to block the precise wavelengths shown to suppress melatonin and disrupt circadian rhythms. Our yellow lenses block 100 percent of harmful blue light between 435 and 465 nanometers, including the intense 455 nanometer spike common in modern LED and screen lighting. Our orange lenses go further, blocking blue and green light up to 550 nanometers for full nighttime protection.
Are prescription options available?
Yes. We offer single vision, reader, and prescription lenses. For progressive prescriptions, custom measurements from your optometrist are required. Contact our team for assistance.
How long does it take to adapt to the lenses?
We recommend wearing bioSpectral yellow lenses daily when exposed to artificial light or technology screens, especially after sunset for at least two weeks to allow your eyes and brain to adjust. Once comfortable, transition to bioSpectral orange lenses after sunset for deeper circadian and melatonin protection.
What is the best way to clean the lenses?
Use the provided microfiber cloth. Avoid abrasive materials or household cleaners. Only use optical lens cleaner or water.
Can I wear yellow lenses at night if I still want to see colors clearly?
Yes, you can. Yellow lenses block 100 percent of the most biologically disruptive blue light wavelengths—particularly those responsible for melatonin suppression and melanopsin activation—making them a strong option for occasional nighttime use.
Many customers start by wearing yellow lenses at night for a couple of weeks while their visual system adjusts, before transitioning to orange lenses for full nighttime protection. Yellow lenses are especially helpful in social settings after sunset, as they still allow you to see colors like aqua, green, yellow, orange, and red while significantly reducing circadian disruption. However, if you're regularly exposed to screens, LED lights, or indoor lighting after the sun goes down, we recommend using orange lenses. These block both blue and green light up to 550 nanometers, offering your body the clearest signal that it's time to wind down, regenerate, and prepare for deep, restorative sleep.
Can I drive at night while wearing yellow lenses?
Some users who are accustomed to wearing the lenses choose to use yellow daytime lenses when driving at night to reduce glare from high-intensity LED headlights. However, this is a personal decision and should be made with caution. BioSpectral Systems does not make safety claims or recommendations regarding driving use. Always prioritize your visual clarity and road safety.
