Kaia Kanepi, playing with glasses on?

They are high definition sunglasses similar to these http://www.reptilesun.com/rx/

They block out the glare of the sunlight and help players to see the ball and their opponent's movement better.

I was engaged when I was 24 and married when I was 26 Our wedding colors were a pale peach and chocolate brown We each had our brothers as witnesses (2 total), it was a very small wedding (14 people were there including us and our reverend) Our reception was held a month after our wedding, and we did not have assigned seating, most people didn't sit, it was a cocktail party We had a small chocolate cake and then a variety of desserts for people to choose, I think there were 5 different choices We went to Maui for two weeks We got married in Gleneden Beach, OR, a tiny town on the coast, just outside of Lincoln City

She's not the only one who wears those all the time. Arnaud Clement and Milagros Sequera both do as well, just to name a few. Back in the 1990's to early 2000's, Natasha Zvereva used to wear them as well. It's nothing new, and apparently it helps them to see better in the sun, and helps them focus more on the ball.

They are probably just sunglasses.She could just have light sensitive eyes.

maybe she wants to cover up her ugly face.
