Understanding the Visual Spectrum

The visual spectrum, the wavelengths of light that the human eye can see, include long wavelength light (red) all the way through short wavelength light (blue). The visual spectrum includes all colors of the rainbow: red, orange, yellow, green, blue, indigo, violet. Red and orange have longer wavelengths and blue/indigo/violet have shorter wavelengths.

Infrared light (heat) is invisible to us because it has a wavelength longer than red, thus the name “infra-red” (literally “Below-Red”). Infrared technology is used in many technologies, including night-vision goggles, LEDs (Light-emitting diodes), and telescopes that look into outer space. Most of the heat emitted from objects is infrared.

Ultraviolet light (UV) is invisible to us because it has a shorter wavelength, thus the name “ultra-violet” (Literally “Beyond-Violet”). UV light cannot be seen, but has the potential to damage our skin and eyes. We need a small amount of UV light to help our bodies make Vitamin D. UV light is also used in inventions, including LEDs (Light-emitting diodes), forensics, fluorescent dyes, neon signs and black lights, and many more.

Why do some colors HURT? Different wavelengths affect an individual’s comfort level. Some studies have indicated that migraine sufferers experience more discomfort with blue- or red-wavelength light. We can help about 90% of people with light sensitivity (photophobia) with our proprietary blend of FL-41 tinted lenses. Axon Optics lenses filter the portion of the light spectrum which is most distressing to people with light sensitivity (photophobia) and its associated conditions. The filter is especially helpful in relieving pain from fluorescent lights, LEDs, and electronic devices – the majority of our modern world. In addition, all of our lenses block 100% UVA/UVB light for the most therapeutic possible lens. Our research continues on the causes of photophobia, both ocular and neurological.

    I experience light sensitivity in general, but more troubling symptoms arise with lights in the red spectrum. I have worn reddish-brown tinted sunglasses in the past and experienced issues, with your lenses being rosy colored would they help me with my sensitivities?

      Axon Optics glasses block the light that has been implicated in triggering sensitivity to light and migraine. Our SpectraShield FL-41 is effective for about 90% of our customers. We offer a lenient return policy so that you can see if our lenses are effective for you. Feel free to email [email protected] for more information.
