To evaluate the effect of a novel moist chamber spectacle wear on the ocular surface and tear functions in a controlled wind exposure environment
Periocular humidity with or without moisture spectacles was initially measured under constant temperature and humidity conditions with a humidity sensor (Sensirion Inc, USA). Twenty-four eyes of twelve probable dry eye subjects according to Japanese dry eye society diagnostic criteria (2 males, 10 females; mean age: 34 years) underwent constant wind exposure at 7 m/sec for 10 minutes with or without moist chamber spectacle wear. Dryness VAS scores, tear evaporation, blink rate and maximal eye opening time measurements (MOT), tear film break up testing, and corneal fluorescein staining were performed before and after wind exposure. Pre and post exposure differences for all examinations were calculated and compared. All tests were performed in the same sequence under the same settings one hour later on the same day with the moist chamber spectacles worn. ANOVA test was used for statistical analyses.
The mean periocular humidity was significantly higher (by 15.6%) with moisture spectacles compared to no spectacle wear (p<0.05). The mean dryness VAS score after wind exposure was significantly higher when no spectacles were born compared to after exposure scores when moist chamber spectacles were worn (p<0.05). The mean MOT score after wind exposure was significantly lower when no spectacles were born compared to after exposure scores when moist chamber spectacles were worn (p<0.05). The mean blink rate increased with wind exposure when no spectacles were worn with no significant changes in the mean blink rate with when the moist chamber spectacles were worn (p>0.05),
The new moist chamber spectacles appear to have favorable effects on dry eye<br /> symptomatology, blink rates and the ability to open the eyes for longer durations in adverse environment conditions such as wind exposure.
