TBI Filters Comparison

Photosensitivity is one of the most common and frustrating symptoms for patients recovering from a concussion or traumatic brain injury. Fluorescent lighting, screens, glare, bright sunlight, the triggers are everywhere, and the right tinted lens can make a real difference in how manageable daily life feels.

The tricky part is that there's no universal answer. What works for one patient may do nothing for another, and the range of filters used in TBI and neuro-visual cases is broader than most people expect. Blues, roses, plums, each blocks a different part of the spectrum and tends to perform differently depending on the patient's specific sensitivities and environment. This tool lets you compare how our most commonly prescribed TBI and concussion filters change the appearance of a real-world scene.

One thing to keep in mind: what you see on a screen is an approximation. TBI patients in particular can be highly sensitive to subtle differences in color and light, and those nuances don't translate reliably across monitors and devices. Think of this as a way to orient the conversation with your patient before they try physical samples, not a substitute for that hands-on evaluation.
