Glossary
optical delay (noun)
A theoretical split-second lag in how quickly one eye transmits visual information to the brain compared to the other. This tiny timing glitch was historically blamed for déjà vu, under the idea that the 'late' eye makes the brain register a single moment twice. It's like a dual-camera setup where one lens has a slow connection, making the second feed feel like a rerun.
