View Full Version : Humidity affects evaporation rate
Ocular Surgery News printed a brief discussion of a small study performed on humidity levels and evaporation.
The difference between 20-25% humidity and 40-45% humidity was a 100% increase in aqueous tear loss. :eek:
I don't know whether this is the exact same study, but ... I found something similar and posted it on the thread called "Location, location, location."
If you scroll down to my "neil0502" name, you can see additional information that supports indrep's post....
The weather here has been--for San Diego--pretty awful (what we call "May gray" at the coast). We've reached an INdoor humidity of 56%--yet another record for us!
The dry eye part of my eye issues is definitely a bit better in this humidity. Unfortunately, that doesn't bode well for a move to a drier climate.
Yeah, we had a warm, humid day today and although I probably still used my drops as much, they did feel a little more comfortable.
Unfortunately the pollen count was really high though - hence allergy misery, but so far its not been too bad this year. Im like that with hayfever though, some years I suffer really bad but others I hardly even notice it and the pollen is around every year so it doesnt really make sense to me. But then non of this does really.
