|
Purpose: This study was performed to investigate the influence of indoor air qualities of an office environment
on dry eye syndrome for wearing contact lens and non-wearing contact lens.
Methods: To study the effects of indoor air qualities on dry eye syndrome for seventy-one subjects, CO2, temperature, humidity, TSP, PM10, HCHO were measured. Each subject was tested by a McMonnie’s dry eye syndrome questionnaire, a Schirmer Tear Test-I (S.T.T-I), a Schirmer Tear Test-II with anesthetics (S.T.T-II), and Tear film break-up time (T.B.U.T) in the their offices.
Results: There was significant relation between the indoor air quality and dry eye syndrome for wearing contact lens and non-wearing when TSP was over 200 μg/m3, PM10 was higher than 86.7 μg/m3 and Formaldehyde was over 0.4~1.0 μg/m3. However, there was no significant effect on dry eye syndrome with CO2 (p=.0146), temperature (p=0.074) and humidity (p=0.053).
Conclusions: It was indicated that CO2, temperature and humidity were no effect on dry eye syndrome in the office environment. However TSP, PM10, formaldehyde, and wearing contact lens were effect on dry eye syndrome. Therefore, the entire management of wearing contact lens and the individual evaluation of the indoor air quality are required.
