How Light Can Impact Photosensitivity

Hundreds of thousands of people can be photosensitive to light, and these experiences can feel extreme for many.1 In fact, some have described their experiences as “losing control” or “having a chaotic storm that jolts through them” or “dealing with an out-of-body experience.” This can be the result of exposure to overwhelming or disorienting environments and/or light sources.

In particular, flashing or strobing lights are a major threat for these extreme outcomes, along with bright lights, striped patterns, and other sources. Here are just some of the aggravating light sources that comes with photosensitivity:

  • Flicker on TV screens or computer monitors
  • High contrast lighting (such as viewing a bright screen in a near-dark room)
  • Malfunctioning light sources, such as fluorescents, that flicker or flash
  • Movies or video games that contain rapid flashes or alternating patterns
  • Strobe lights, such as those at a concert or athletic game
  • Sunlight flickering through trees, glimmering on water, or streaming through the slats of window blinds
  • Emergency lights on vehicles or visual fire alarms

Striped or repeating patterns, even in static imagery, can create similar photosensitive responses, and certain wavelengths of light have been shown to more negatively affect photosensitivity as well.2-4 Plus, this light comes at us from all directions—our screens, fluorescent lighting, LEDs, and sunlight.5

It is no surprise that light management is a critical ingredient. TheraSpecs filter unique parts of the light spectrum to give powerful defense against flashing, strobing and contrasting lights as well as disruptive patterns.


TheraSpecs Z-Blue™ is crafted to provide optimal protection against uncomfortable lighting and patterns. For extreme photosensitivity, especially to flashing or strobing lights, we first recommend trying Z-Blue max strength.

TheraSpecs FL-Sun™ can be worn outside to help manage sunlight flicker through trees to provide protection. (Z-Blue max can also be worn outdoors—FL Sun is an option if you’re looking for a darker, polarized lens.)
