A pocket watch swings across your screen. Your eyes follow it. The camera watches your pupils the whole time.
From your saccade lag, iris constriction, blink rate, and accommodation speed — the system computes your exact synthetic lens prescription. No eye chart. No optometrist. Never been done before.
