Brief Summary
The objective of the study is to compare the rate of tear evaporation, measured with a novel evaporimeter, before and for one hour after an eye drop containing nano-sized oil droplets has been instilled.

Outcome Measures
Primary Outcomes (1)
Tear Evaporation Rate
Tear film evaporation rate (% relative humidity per second) was performed using a novel evaporimeter as a non-invasive measurement of tear film evaporation. The slope was calculated from the change in humidity between 7 to 17.5 seconds while the eye was open and between 10 to 17.5 seconds when the eye was closed. Data from the right eye was analyzed.
Baseline (Prior to instillation); 10, 30 and 60 minutes post instillation of eye drop
Study Arms (2)
Non-Dry Eye
EXPERIMENTALInstill eye drop and perform followup assessments on people with a Ocular Surface Disease Index score \<13 and a non-invasive Keratograph break-up time of \>/= 10 seconds in the worst eye
Dry Eye
EXPERIMENTALInstill eye drop and perform followup assessments on people with an Ocular Surface Disease Index score \>/= 13 and a non-invasive Keratograph break-up time \</= 5 seconds in the worst eye
Interventions
Systane Complete will be instilled and rate of evaporation assessed before and after.
