Seasonality and Dry Eye

I recently read an article from a group at UC Irvine regarding Google Trends data about dry eye. Basically, the method they use is to analyze Google search data as a measure of how much dry eye is actually in the community. One of their conclusions was that the Fall is the time of year with the least amount of dry eye related search. The time of year with the most search is Spring, followed by Winter. My personal interpretation of this is that, with the low temperatures in Winter, the humidity is lowest in Winter, which contributes to Winter being a “high time” for dry eye. Spring is a bit more curious, since the result can’t be chalked up to humidity. Again, my personal interpretation of this is that there are more allergies (specifically allergic conjunctivitis) in the Spring, which can overlap with dry eye, which drives Spring to be the worst season for dry eye search.
