Not sure where to post this one!

When I first put on my sunglasses my right eye ALWAYS steams up the lens - it happens over and over, I remove it, wipe it and put it back on and it happens again. Lasts a few minutes then stops.

I tried googling it but came up with nothing.

Anyone ever heard of this? Wondering if its just odd and I have to deal with it or if I should go to the eye doctor?
