Migraine Glasses Lens Coatings Explained
Share
FL-41 tint gets most of the attention with migraine glasses, but additional lens coatings can add meaningful function on top of the core light-filtering.
Anti-scratch coating
A scratch-resistant coating helps lenses stay clear over daily use, since scratched lenses can scatter light in ways that undermine the tint's filtering effect.
UV protection
UV coating blocks ultraviolet light separately from FL-41's visible-light filtering, adding a layer of eye protection relevant especially for outdoor use.
Anti-fog coating
For anyone who moves between temperature extremes — stepping from air conditioning into summer heat, for example — anti-fog coating keeps lenses usable without constant wiping.
Depending on how you'll use them, checking which coatings come standard on your migraine relief glasses helps you know what you're getting beyond the tint itself.
