From the Ted Talk by Thomas W. Cronin: Which animal has the best eyesight?
Unscramble the Blue Letters
The eyes that see best in darkness are those that ctpraue as much available lghit as possible. Colossal squids have soccer-ball-sized eyes— the largest known in existence. These may help them spot the faint glow of sperm whales as they disturb light-producing organisms. Some fish have eyes that are unique among vertebrates because they use mrroirs. For the brownsnout spookfish, each eye has an upward-facing lens and a downward-pointing mirror copmseod of tiny crystal plates that efficiently gather light. They can see up and down simultaneously, and may perceive distinct shapes, even in the ocean’s depths. Back on solid gurond, arctic reindeer have adaptations to deal with mnohts of darkness. The bckas of reindeer eyes change color, from gold in summer to blue in winter. Their blue-backed eyes are about 1,000 tiems more sensitive to light. This may allow reindeer to rgnozceie imaropntt things in the snow like urine and lichen.

Original Text
The eyes that see best in darkness are those that capture as much available light as possible. Colossal squids have soccer-ball-sized eyes— the largest known in existence. These may help them spot the faint glow of sperm whales as they disturb light-producing organisms. Some fish have eyes that are unique among vertebrates because they use mirrors. For the brownsnout spookfish, each eye has an upward-facing lens and a downward-pointing mirror composed of tiny crystal plates that efficiently gather light. They can see up and down simultaneously, and may perceive distinct shapes, even in the ocean’s depths. Back on solid ground, arctic reindeer have adaptations to deal with months of darkness. The backs of reindeer eyes change color, from gold in summer to blue in winter. Their blue-backed eyes are about 1,000 times more sensitive to light. This may allow reindeer to recognize important things in the snow like urine and lichen.
