This study was undertaken to evaluate the effect of a novel humidifying eyeglass-shaped device—ultrasonic moisture glasses—on dry eye signs and symptoms.
A total of 18 subjects with dry eye symptoms underwent a crossover test. A water cartridge was set on each temple of the eyeglass-shaped device. All subjects randomly wore the device twice in different settings, each for 10 minutes. Subjects wore the glasses once with the cartridges filled with water (the intervention group), and once with the cartridges empty (the control group). The order was randomized. We evaluated tear film break-up time (TBUT) and fluorescein staining score just before, immediately after, and 10 minutes after wearing the device. We also assessed functional visual acuity (FVA), blink frequency, and visual analog scale (VAS) score just before and immediately after wearing the device.
TBUT, blink frequency, and VAS improved in the intervention group (all P < 0.001) and exhibited significant differences between the intervention and control groups.
Wearing the ultrasonic moisture glasses for 10 minutes improved tear stability and decreased dry eye symptoms in this cohort of subjects.
These findings show that the ultrasonic moisture glasses are an effective device for improving dry eye signs and symptoms.
