Example sentencesExamples
- Visual pigments have also evolved to perform specialized functions, such as color vision and scotopic vision.
- The photopic curve is for normal vision, and the scotopic curve is for eyes that are adjusted to the dark.
- Honeybees, forced to feed under dim light levels are colour-blind just as humans are under scotopic conditions
- The low dark noise of rods allows the scotopic system to reliably detect a flash eliciting less than 10 effectively absorbed photons.
- Using an extremely low-light projector and other devices, we get demonstrations of night adaptation, blind spots, mesopic and scotopic vision, peripheral vision, autokinesis and flash blindness.
