Frequently Asked Questions

Why am I more sensitive to light during a migraine?

Migraine causes hyperexcitability of brain pathways that process light, making normal light feel painful. Lying in a dark, quiet room often helps.

Are blue-light glasses helpful?

Evidence is mixed. They may help some people with eye strain, but they aren't a standard treatment for photophobia. FL-41 lenses have better support for migraine-related light sensitivity.
