Research Studies

If you join the study, we will ask you to answer questions about the symptoms of your dry eye. We will measure the humidity around your eyes; this will be done by asking you to wear a pair of non-framed eyeglasses with a small hygrometer attached to the frame in front of your eyes. Hygometer measures the humidity in the air. Neither the eyeglasses nor the hygometer will touch your eyes. We also will take photographs to document your mask fit. We will exam the surface of your eyes, which involves using fluorescein eye drops to stain the outer surface of your eye. You may feel a slight stinging sensation when the dye is first applied. After a few moments, the dye will feel like normal liquid on the eye and will no longer be uncomfortable. The fluorescein eye drops are considered safe. There is no lasting stain, but the eyelids and cheeks may be colored, which can be wiped off by gentle washing.
