Few other advances were made in optics until after 1000 AD. To produce a dark adaptation curve, subjects gaze at a pre-adapting light for about five minutes, then absolute threshold is measured over time figure 1.

Let your imagineers pretend shaving cream is a cloud that holds colorful raindrops. 14 Cornsweet, 1970 and 0. Kid-Safe Lava Lamps A lesson in: Density and intermolecular polarity.
For extremely short pre-adaptation periods, a single rod curve is obtained. These lead to all kinds of rainbows showing up around our house on sunny days which the kids are just fascinated by!
The sensitivity of the rod pathway improves considerably after 5-10 minutes in the dark and is reflected by the second part of the dark adaptation curve.
