Is Laser Hair Therapy Safe for Your Eyes?
Laser eye therapy and laser hair therapy differ by just one word, and both are intended to correct a problem. In the case of laser eye therapy it’s vision loss, in the case of laser hair therapy it’s hair loss. However, they use very different kinds of lasers. The surgical lasers used for laser eye therapy are definitely not safe for your scalp. But what about the other way around? Is laser hair therapy safe for your eyes?
Wavelength and Energy
Time to recall your high school physics classes. Light is composed of photons emitted at various wavelengths. A shorter wavelength implies that a light beam has more energy, while a longer wavelength, therefore, implies it has less energy. Think of a “wavelength” as the distance between two crests or troughs of an oscillation. If a light wave is advancing slowly, it has less energy and its wavelength is longer. But if a photon is bouncing up and down quickly, as you may have guessed, not only is its wavelength shorter, but its energy is through the roof.
A vast majority of the electromagnetic spectrum is not visible to the human eye. For example, we can’t actually “see” radio waves. We also cannot detect high-energy x-rays and their harmful radiation without the right equipment. X-rays have wavelengths of less than 10 nanometers (nm) and have enough energy to penetrate your body’s flesh and muscle. This is exactly why they are effective when you want to look at your bones.
Laser Hair Therapy and Your Eyes
So what does this have to do with laser hair treatments? Specifically, what does this mean for Theradome laser hair therapy helmets? A lot. You may recall that laser light is red in color, which falls between a range of 622 nm and 780 nm. This means it’s not very energetic compared to x-rays or even harmful UV light. UV light hovers just below 400 nm. Plus, laser hair therapy does not utilize collimated lenses – meaning the light propagates, which diffuses its power.
Then there’s your body’s innate urge to protect itself. Logic dictates that you won’t stare at the sun, and if you do, you’ll end up feeling the urge to blink. And unless you’re a robot, you won’t be able to fight off your body’s survival instincts to preserve your eyesight. The same happens with red light. None of 80 of Theradome’s 680nm lasers will actually harm your eyes. But even if they could you wouldn’t be able to stare into them without blinking anyway.
In the case of our Theradome laser hair restoration helmet. not only are our eighty 678-nm lasers not collimated, as mentioned above, but chances are you wouldn’t be able to stare directly into the lasers before blinking and thus avoiding damage to your eyes.
This is all good news! It means there’s no need to worry about Theradome’s laser’s affecting your eyes. Absolutely no protective eyewear is needed. While completely safe, Theradome is remarkably effective at stopping hair loss and growing new hair. In fact, laser light therapy is the only hair restoration therapy with absolutely no side effects.
