Objective of this study is to evaluate the tolerance and potential benefit of moisture chamber glasses for dry eye in an Asian population. In this clinic based prospective interventional study, we aim to recruit patients (until 10 patients complete the study) who have evaporative dry eye due to exposure to environmental stress (such as frequency of out door activities) and keen to try out moisture chamber glasses/ eyewear from the dry eye clinic in Singapore National Centre. After informed consent, these patients will be prescribed 7eye( Panoptx)™ moisture chamber glasses/eyewear for 3 months and will be monitored on a diary for the amount of time wearing eyewear for 2 weeks and the number of eye drops for each type of medication used. Other outcomes will be changes in symptoms of dry eye using visual analog scale, as well as objective signs of dry eye (eg. corneal fluorescence staining and tear break up time (TBUT). As moisture chamber spectacles are currently not available as a treatment option for dry eye in Singapore, the findings of this study will give an insight to the efficacy of this new treatment modality in our population.
Percentage of time wearing moisture chamber glasses while outdoors during 2 weeks of the study. [ Time Frame: 2 weeks during 3 months ]
Secondary Outcome Measures
1.Number of eyedrops per day for each type of medication used at the end of study vs at the commencement of study,symptoms of dry eye (using the VAS),corneal fluorescence staining and tear break up time(TBUT). [ Time Frame: 3 months ]

Accepts Healthy Volunteers:
1. Subjects with evaporative dry eye as assessed by the PI in the dry eye clinic and has occupational or lifestyle requirement to be exposed to a hyper-evaporative environment.
