We entry the people who meet all conditions below (No.1-4) as dry eye group.
And we entry the people who meet conditions (No.1-3) without dry eye disease (DED) as control group.

Diagnosis was established according to the Japanese DED diagnostic criteria, as follows; (1) presence of dry eye symptoms; (2) a.presence of qualitative or b.quantitative disturbance of the tear film in 1 or both eyes (a.Shirmer test <= 5 mm or b.Tear Break Up Time <= 5 seconds); and (3) presence of conjunctivocorneal epithelial damage (total staining score => 3 points) in 1 or both eyes. The presence of all 3 criteria was necessary for a definite diagnosis of DED.
People who meet one of the following conditions are excluded from both dry eye group and control group.
1.Those which can not obtain informed consent for ophthalmic examination.
2.Those that can not obtain informed consent for hair collection
