I've heard and read in numerous places over the years that this occurs. It apparently is related to how and why your windows block uvb and only let in a small amount of uva (try tanning in your window to test this one out.) What I wonder is if lacking that protection of the natural lens increases the risk of eye cancers or other complications.
