If you arrived here looking for a “perception test”, please treat Instinctle as a game. The five tests — a hidden intersection, a path length, a vanishing point, a time midpoint, and a lightness match — are designed for a two-minute daily, not for clinical screening. A low score on Between with the sound off is still a fair game score, because the flashes are the cue; it is not a hearing result. A miss on Aftertone is often the illusion doing its job, not a problem with your eyes.
Nothing on this site is medical advice. If you have a concern about your vision or hearing, talk to a qualified professional.
