rod–cone break

the shift in visual sensitivity that occurs during dark adaptation when the sensitivity of the retinal rods first exceeds that of the retinal cones. When visual sensitivity is measured in the dark following a very bright flash of light, the cones reach maximum sensitivity after about 7 minutes. However, overall visual sensitivity continues to improve for about 20 more minutes as rhodopsin regenerates and the rods reach their maximum sensitivity.
