The "rod-cone break" in the dark adaptation curve occurs after about 7 minutes in the dark. During this time, the cones adapt to the dark and begin to function better in low-light conditions. However, after about 7 minutes, the rods (which are more sensitive to light) take over and become the primary photoreceptor responsible for vision in dim light. This transition is known as the "rod-cone break."
