They weren't by choice, in fact it was much more by chance.

In the first half of Butler's final home game of the season against Loyola on February 26th, Brad Stevens vision became blurry.

As time ticked off the clock, things only got worse, to the point where Stevens was forced to seek medical treatment and miss the second half of a 63-56 win over the Ramblers.

"It was called corneal edema," said Stevens. "My eye basically swelled up, my cornea swelled up and it glassed my eye over."

For senior Matt Howard, it put a damper on his senior night since the coach who recruited him and coached for four years was absent due to the unusual ailment.

"That situation was really scary-and odd-for all of us," said Howard-but little did he or Stevens know what it would bring along.

To help protect his eye, Stevens began wearing glasses during the games. This began with the Bulldogs' Horizon League tournament semifinal victory Cleveland State in Milwaukee and has continued ever since.

"Yeah, they're great," said Stevens of the glasses. "They haven't lost yet."

It's true. Butler would go on to beat Milwaukee in the Horizon League title game at the U.S. Cellular Arena to clinch an automatic bid to the NCAA Tournament.

Though the glasses Stevens then watched his team pull out two thrilling last second victories over Old Dominion and Pittsburgh to advance to the NCAA's Sweet 16 round in New Orleans this week.

"I'm sure that's a big positive in his mind for wearing them," said Howard. "I can guarantee that."

To be fair, the Bulldogs did win seven consecutive games before the glasses came into play, but the fact that he's worn them during a critical stretch of Butler's season has come to the attention of fans. A number of tweets over the past week concerning the team have mentioned the coach's glasses and the potential intangible impact they have had.

"After the game, we let him know that it was a trending topic on Twitter," said guard Shelvin Mack about the coach's glasses, which are often tagged on the social media site at #bradstevensglasses.

As far as a true impact on coaching the team as they move forward, Stevens could only think of one thing it might help or hinder.

"I hate jogging in them," said Stevens of the glasses. "But other than that, I'm good."
