How the Eye Works in Low-Light

"New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels," reports Science Daily. "Scientists had thought that the strength of rhodopsin's signal determines how well we see in dim light. But UC Davis scientists have found instead that a second step acts as a gatekeeper to correct for rhodopsin errors. The result is a more accurate reading of light under dim conditions. A report on their research appears in the October issue of the journal Neuron." Read more.
