Why does Tony Sparano wear sunglasses everywhere?

Answer 1

Sparano had a scare as a teenager that could have prevented him from becoming a coach. He worked at a restaurant in Connecticut, and when hot grease splashed into his eyes one day, he lost his vision for weeks. His eyes have watered ever since and remain sensitive to light. As a result, he often wears sunglasses indoors or at night, and the lights in his office generally stay off.
