BlueSync was designed with the world’s leading photobiology expert to selectively transmit and filter specific wavelengths of light for desirable biological effects.

BlueSync filters UVA, UVB, and HEVL—short-wavelength light which causes damage to cells with prolonged exposure.

BlueSync selectively emphasizes long-wavelength blue light, with a peak transmission around 480nm, the exact range responsible for stimulating the circadian-rhythm-controlling cells in the eye. In doing so, BlueSync strengthens the body’s circadian rhythm, increasing energy levels, mood, focus, motivation, and performance.

BlueSync transmits the wavelengths of light associated with regeneration—red and near-infrared—shifting the balance of daylight toward protection and healing.

BlueSync offers the perfect balance of protection, activation, and healing—the first lens of its kind, and a revolution in therapeutic eyewear.

Use BlueSync in the morning hours, and throughout the day, whenever you want a natural increase in energy, mood, focus, motivation, productivity, and overall physical and mental performance.

You can use BlueSync when you are out for a walk or a run, hiking, training, playing sports, or even just working.

BlueSync can be used indoors, but its effects are strongest in daylight (so if there are many large windows around, it will be more effective).

Discontinue use of BlueSync in the late afternoon, or whenever you want to begin to wind down for the day.

If you need to perform in the late afternoon or evening, you can use BlueSync at this time as well (but note that performing at these times of day will naturally have a disruptive effect on the natural sleep cycle and regenerative processes).

Anyone who wants to feel more energy, increased motivation and focus, better sleep, and improved health and well-being.

The circadian rhythm consists of two primary periods: wakefulness/activity, and rest/regeneration.

By increasing the amplitude of either phase of the oscillation, it will naturally increase the amplitude of the other. For example: by sleeping and resting more deeply, you have more energy to be active, focused, and to perform during the day, mentally and physically.

Similarly, anything that increases the peak amplitude of wakefulness during daytime will increase the depth and quality of sleep at night. Major factors that can amplify the circadian rhythm are light exposure, meal timing, temperature, and physical activity. BlueSync amplifies the light which increases the peak amplitude of the circadian rhythm, thereby also increasing depth and quality of sleep at night.

No, in fact, blue light is essential for optimal health and well-being. Blue light regulates the body’s natural circadian rhythm, which controls a variety of biological processes essential for overall health and well-being.

Blue light is only “bad” when it is unnaturally separated from the healing, regenerative part of the light spectrum (red and near-infrared), which is the case with modern artificial lights and screen devices. Sunlight contains a natural balance of wavelengths, so that blue light is balanced by healing wavelengths. Also, we naturally limit our sunlight exposure; but no one is limiting their exposure to artificial lights.

Additionally, blue light can be “bad” when we are exposed to it at an unnatural time. In nature, it is light during the day, and dark at night. Artificial lights at night, emitting blue light, “trick” the brain into thinking it’s still daytime, disrupting the release of the body’s most important anti-oxidant, anti-aging, anti-cancer molecule, melatonin.

BlueSync is designed to be used in the morning and during daytime to emphasize the specific wavelengths of light that strengthen the circadian rhythm, increasing energy levels, mood, motivation, physical activity, and overall health.

At Ra Optics, we agree that the mainstream health authorities and government stances on light are not exactly correct.

Considerable scientific evidence makes it clear that some quantity of UV light exposure, especially UV-B, is not only beneficial, but essential for the natural production of vitamin D, and optimal health. We recommend our customers ensure ample exposure to unfiltered, full-spectrum daylight—but in a highly intentional and targeted manner.

However, some modern health “experts”, especially in the biohacking world, have taken this too far, suggesting that more is always better, and advocating for maximum sunlight exposure.

This is dangerous advice and predisposes adherents to—at best—accelerated skin and eye aging and damage, and—at worst—increased risk of skin cancer and other related issues.

Indigenous cultures living in extreme solar environments made every effort to protect themselves from the damaging effects of excess sun exposure, which they could see and feel. For example, Inuit tribes living in Arctic climates fashioned “snow goggles” out of wood or bone to prevent snow blindness.

The incidence of cataracts is significantly higher in high-intensity solar environments like India, and especially in high-elevation regions like Nepal and Tibet.

Hence, intelligent protection from UV light is not only beneficial, but essential, especially in high-intensity solar environments.

At Ra Optics, we also acknowledge the risks of HEVL (high-energy visible light), which are almost completely ignored by the vast majority of existing sunglass products.

HEVL is an acronym for “high-energy visible light”. Since ultraviolet light is invisible, HEVL refers to the range of the visible light spectrum which contains the most energy. These are the short wavelengths of blue light.

Similar to UV light, the high amount of energy contained in HEVL is capable of causing oxidative damage, damaging cells and tissues. The effect just occurs over a longer period of time.

By filtering UVA/UVB, but not HEVL, sunglasses can actually increase the risk of damage to the eyes, since someone can feel that they are protected, and spend longer periods of time in the sun, ultimately being exposed to dangerously high doses of HEVL.

HEVL is not only a concern from sunlight, but also from artificial light sources, because most people now spend extended periods of time under these light sources and staring at screen devices, every day.

For this reason (among others), all Ra Optics lenses offer maximal HEVL protection.

Yes, we recommend exposing yourself to unfiltered sunlight at sunrise, for approximately 10 to 20 minutes, to experience its many benefits.

At any other time of day, whether mid- or late morning, mid-day, or early afternoon, BlueSync offers a powerful increase in energy levels, mood, focus, motivation, and overall performance. By emphasizing the wavelengths of light that stimulate the circadian rhythm, BlueSync is able to offer these effects more quickly than exposure to unfiltered sunlight.

BlueSync offers unique benefits by filtering UVA/UVB and short-wavelength blue light (HEVL), which can be damaging in excess, while selectively transmitting the longer-wavelength blue light that strengthens the body’s circadian rhythm, and also transmitting the healing red and near-infrared wavelengths of light.

We recommend discontinuing use of BlueSync in the late afternoon, whenever you are ready to wind down (unless you need to perform in the evening).

Jet lag occurs when we travel long distances in short periods of time, especially by plane, because our internal biological processes become misaligned from the external environment. We may want to sleep during the day, and have trouble sleeping at night; feel tired and groggy; experience constipation and digestive discomfort, dehydration and so on.

BlueSync can improve symptoms associated with jet lag by helping the body clock to more rapidly synchronize to the new environment.

If you are a shift worker, you may experience effects similar to jet lag on a regular basis because your profession forces you to stay awake under the influence of artificial light through the night, and you end up needing to sleep during the day. BlueSync can help you to improve your circadian rhythms during daytime, increasing energy levels, alertness, and mood, even when the demands of your profession keep you awake late into or through the night.

Lastly, if you are up late at night, whether out and about or enjoying time at home, you may find that you wake up feeling groggy—especially if consuming alcohol. Natural effects of sleep disruption include impaired focus and memory, brain fog, increased stress, decreased performance (as well as many other internal effects, including disruptions to metabolism as well as hormone and neurotransmitter production). BlueSync helps to re-activate your physiology, so that you can function and feel better the day after a late night—and even give you the motivation to help make better decisions going forward.
