Which photoreceptors recover faster after bleaching?

Explanation:
After bleaching, recovery depends on how fast the photopigment can be regenerated. Cones have a faster pigment regeneration cycle, so their sensitivity returns quickly after light exposure. Rods rely on rhodopsin, which bleaches and then must go through a longer recycling process to reform the pigment, so their sensitivity comes back more slowly. This means you regain functional vision in bright light via cones within minutes, while rod-based (low-light) sensitivity takes longer to rebound. So cones recover faster after bleaching.
