What a wild ride these last 10 years or so have been.
In my mind, there have been three distinct eras of dry eye disease (DED) care over the millennia. These three time periods have neither established names nor officially defined boundaries like the myriad generations we use to describe our population here in the U.S. (baby boomers, etc). To the surprise of exactly no one who has read my drivel, I will therefore take it upon myself to declare what I think these eras are and then let the rubble fall wherever it may.
We can think of the decades prior to the 21st century as the Age of Innocence.
