Ra Optic lenses have been proven to specifically target the harmful frequencies emitted by phones, computers, screens and LED lights. You may have seen clear lens blue blockers, sometimes called “computer glasses”. Unfortunately, these do not block the same specific, dangerous frequencies of light emitted from screens or lights that Ra glasses do and are simply a marketing gimmick.

Technology for Day and Night

The most important function of Artificial Light Glasses is to protect our sleep, because artificial light destroys our melatonin level, sleep quality, and overall health. Ra offers separate glasses for day and night use. While others are only focused on selling lenses that are as clear as possible, the folks at Ra offer night lenses that block all blue and green light wavelengths in order to protect your eyes, sleep, and health.

Fashion and Function

Ra Optics was founded on the belief that you shouldn’t have to sacrifice style for results. So, they put the most effective lens technology into the most attractive frame styles to date. All Ra frames are made from top quality materials, including ultra-lightweight TR90 and plant-based cellulose acetate.

More On The Harmful Effects Of Blue Light

You've no doubt heard the news that blue light exposure (especially at night) is now up there with cigarette smoking, sitting for long periods of time, and constant airline travel when it comes to increasing your risk of chronic disease. Scientists worldwide are now warning of the dangers of night-time exposure to artificial, blue light.

An overwhelming body of new research has found that the harsh blue light emitted by digital devices such as smartphones, tablets, laptops and TVs wreaks havoc on your sleep and overall health, and that late night activities such as gaming sessions, checking social media and taking selfies are increasingly linked to issues like diabetes and obesity.

Heck, light pollution is now even classified as a carcinogen!

That's because the harsh blue light from high energy devices suppresses your body's normal secretion of melatonin, a naturally occurring hormone that promotes healthy sleep. Blue light basically fools your brain into thinking its still daytime, and the ensuing disruption of your normal sleep cycles is linked to elevated risk of cancer, cardiovascular disease, diabetes and other metabolic disorders, as well as to psychological stress and depression.

This blue light exposure is even more damaging for children as explained by Dr. Dave Lee, from the Children's Eye Center, to Fox News: “As we get older, the lens in our eye naturally gets a little bit more yellow. That acts as a natural filter for that blue light. But children have little or no yellowing to their lens so they don't have that natural protection.”

So what's the solution?

Many health-conscious, so-called “biohackers” have taken to wearing orange-tinted blue light blocking glasses, which filters out the specific blue wavelengths of light shown to cause insomnia. This hack is now spreading to the general population, with the result that it's now become quite acceptable to venture out at night, watch a movie, go to a party, or simply work on a computer or read an e-reader at home while wearing blue-light blocking glasses.

And these things actually work. A Swiss study, published in The Journal of Adolescent Health, showed that when the teenage boys donned orange-tinted glasses, also known as blue blockers in the evening for a week, they felt “significantly more sleepy” than when they wore clear glasses. Separate, independent studies at the University of Toledo in Ohio, University of Lavel in Quebec City, and the Corvalles Psychiatric Clinic in Oregon among others have backed up these findings.

Research conducted at the Corvallis Psychiatric Clinic in Oregon suggests that the simple amber, blue-light blocking glasses can be an effective and inexpensive treatment for insomnia and sleep deprivation, and also be an effective treatment of mental illnesses such as bipolar disorder.
