"Blue light exposure can negatively impact your health. When you’re staring at a screen all day long (which is fake blue light) and especially at night, it will mess with your body’s circadian rhythm. Your body won’t be able to understand if it’s ready for bed at night. This is why it’s so important to use blue light-blocking glasses at least 2-3 hours before bedtime so your body can produce melatonin and decrease cortisol production. To help my sleep, I always wear my Ra Optics blue blockers when the sun goes down. I put them on and immediately get tired because my body knows it's time to lower cortisol and start producing melatonin."

How does Light

affect your Health?

...and how Ra Optics can help.

Blue light tricks your brain

During daytime, isolated blue light (from screens and office lighting) stimulates the brain and body for activity, effectively “force-stressing” people into more work and productivity, by affecting our hormones and neurotransmitters — in the workplace or at school, for example.

At night, blue light tricks the brain into thinking that it is daytime, when it is not. It causes the brain to halt the natural secretion of melatonin -- which is a hormone that prepares our brain and body for sleep, when light (especially blue light) is no longer present in the environment. Sleep quality will be impaired, and you can become restless, waking up during the night, and wake up the next day without optimal energy.

Articial blue light

Modern, man-made light sources have been able to isolate certain wavelengths of light, and utilize blue wavelengths to stimulate the brain and body for activity, effectively “force-stressing” people into more work and productivity, by affecting our hormones and neurotransmitters — in the workplace or at school, for example. [1][2]

Protect your Circadian Rhyhthm

Circadian rhythms are a set of physiological, psychological, and behavioral changes that occur within a 24-hour cycle. These inherent patterns are predominantly influenced by light and darkness and impact a wide range of organisms, including humans. [3][4]

‘Circa’ is Latin for “approximately”, and ‘dies’ means “a day”; therefore, circadian means “approximately a day”. Researchers recently discovered that we we possess internal cycles that follow almost exactly the length of a day, hence this name.

In 2017, the Nobel Prize in medicine was awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their discoveries of molecular mechanisms that control circadian rhythms. [5]

They discovered that the primary driver of the circadian rhythm is light. Which makes sense, considering that a day is created by one full rotation of the earth around its own axis, and the most significant change in the environment during this period is the shift between the presence and absence of daylight.

In 2017, the Nobel Prize in medicine was awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their discoveries of molecular mechanisms that control circadian rhythms.[3]

One of the worst things we can do to our health is to regularly disrupt our 24-hour cycle (circadian rhythm), which is responsible for signaling every cell in our body what to do and when to do it. [4][5]

Along with sleeping and waking, the circadian rhythm controls the activity of our metabolism, the production of key hormones and neurotransmitters, the process of excreting waste, thirst, and more.

How can blue light be harmful to my health?

Light is a spectrum of colors with each color being of a differing amount of energy and wavelength. Red light at one end, with longer wavelengths and less energy and blue light at the other, with high energy and shorter wavelengths.

Sunlight, contains all the colors of the visible spectrum in balance, and was our only source of light, until humans invented artificial light - oil lamps, the lightbulb, computers etc. Today in our digital world we are exposed to light on a constant basis, much of it the artificial blue light emitted by devices and light bulbs. Its cumulative effect is having negative impacts on our health, from disturbing our sleep to harming our eyes.

Can I exchange my glasses if I don't like them?

Absolutely! If you reside within the U.S.A. we even offer free shipping, returns and exchanges.

How long does it take to start seeing benefits?

In most cases, it takes about two weeks for your eyes to adjust and for you to start seeing the full benefits of our lenses.

How much is shipping?

We offer free shipping and free returns within the USA. The costs for international orders depends on the geolocation and order value.

How exactly do Ra Optics lenses work?

Ra Optics lenses are embedded with advanced pigment technology that absorbs the specific, harmful wavelengths of light that we want to protect from.

So, light comes into the lens, and just as melanin in human skin absorbs high-energy radiation to prevent us from sunburning, our lenses absorb high-energy blue light wavelengths, which can cause ocular damage, sleep disruption, and negatively impact health.

Since blue light increases the production of harmful free radical molecules (reactive oxygen species, i.e., ROS), blocking this blue light naturally reduces the production of these molecules, allowing retinal cells and the entire eyes to regenerate and to function more optimally.

At night, additionally, blue light has been clearly demonstrated to suppress the body's natural production of melatonin—the body's sleep hormone—which is crucial for cellular repair and a variety of anti-oxidant, anti-aging, and disease prevention processes.

By simply blocking this blue light, we are able to both protect retinal health, and, in the evenings, support the body's natural secretion of melatonin. During the day, this means reduced or even eliminated eyestrain, headaches, and fatigue; a more balanced state, and naturally increased energy levels, focus and productivity. In the evening, this means relaxing naturally without the need for external substances; falling asleep more easily, sleeping more deeply, and waking up with more energy in the morning, ready to take on the day.

What is your return policy?

We also offer a 30-day money-back-guarantee. After tens of thousands of glasses sold we are very confident that our glasses make a positive impact on people's health. If you are not completely satisfied with your order, you can return your glasses within 30-days from the day your glasses were delivered. No questions asked!
