Abstract

RESULTS: The mean dryness VAS score after wind exposure was significantly higher when no spectacles were worn or when conventional spectacles with no moist chambers were worn compared with after exposure scores when moist chamber spectacles were worn (P=0.02). The mean of tear evaporation rate from the ocular surface and blink rate increased significantly with wind exposure when no spectacles were worn or when conventional spectacles with no moist chambers were worn (P=0.04). There were no significant changes before and after wind exposure when the moist chamber spectacles were worn (P=0.1).

CONCLUSION: Moist chamber spectacles appear to have favorable effects on dry eye symptomatology, tear stability, and blink rates in adverse environment conditions such as wind exposure.

PURPOSE: To evaluate the effect of moist chamber spectacle wear on the ocular surface and tear functions in a controlled wind exposure environment.

METHODS: Twenty-eight eyes of 14 probable dry eye subjects (4 men, 10 women; mean age: 34.5 years) underwent constant wind exposure for 10 min without spectacle, with conventional spectacle wear, and with moist chamber spectacle wear. Dryness Visual Analog Scale (VAS) scores, tear evaporation, blink rate, tear film breakup testing, and fluorescein staining were performed before and after wind exposure.
