What They See

Updated severity labels for myopia and hyperopia to match clinical guidelines. Prescription diopter thresholds now align with the scales used by eye care professionals.

Ever wondered what the world looks like through someone else's eyes? What They See turns your iPhone camera into a real-time vision simulator. Point it at anything and instantly see how someone with colorblindness, cataracts, myopia, or dyslexia experiences the world.

Built with optometrists and educators in mind, but made for anyone who's ever been curious about how other people (and animals) see.
