Technologies allow us to measure tear osmolarity or identify above normal ranges of matrix metalloproteinase-9 levels. Other diagnostic tools, such as meibomian gland imaging and lipid layer analysis, have transformed the way we assess appropriate tear production. We have remarkable tools to identify and help us monitor ocular surface conditions that may affect comfortable lens wear. In light of all this, do we still need our vital dyes, specifically fluorescein?
