Tear Osmolarity Part II: Choosing the Right Artificial Tear
One way to put dry eye into different categories is to separate LOW TEAR PRODUCTION from TEAR EVAPORATION. This can be done by simply looking at your tears and measuring things like the amount of tears you have, or how long your tears stay smooth on the front of the eye. But these two things have lots of overlap. For example, some times low tear production can cause tear evaporation!
Here's where the tear osmolarity test from TEARLAB comes in. Internal findings made by Dr. Darrell White have shown that your symptoms can be effectively treated if we choose the type of artificial tear based on your osmolarity results. In other words, if you have both a low tear level AND a fast tear evaporation, the primary cause is likely to be found in the osmolarity test! For example, if your osmolarity is HIGH, poor tear production is probably what came first.
