Sports fans may not have recognized Bob Costas in his early reports from the 2014 Sochi Winter Olympics because of his unfamiliar eye wear. Wags likened the bespeckled sportscaster as doubling as Clark Kent or more mature Harry Potter. There is even a parody Twitter account chronicling the situation
As NBC started its 18 days of intense coverage of the XXII Winter Olympiad, Costas came down with an eye infection, so he needed to wear glasses on air. Network doctors think that it is a minor infection which should resolve itself by the weekend.
Considering all of the Sochi Problems, especially with the special non-potable Sochi water coming from "five star" hotel taps, it is easy to see how Costa could get pink eye.
It is a reminder to don't drink the water.
