An infrared sensitive camera can be focussed on the eye surface to produce a sequence of thermographs that allows monitoring of the spreading of the tear film across the ocular surface after a blink, and also the stability and changes of this film after the spread. This enables: (a) discrimination of different dry eye aetiologies； and (b) monitoring the effects on the tear film of: different blink regimes； eye drops； contact lenses, ocular diseases (e.g. allergies, shingles and Sjdgren's syndrome)； and of ocular surgeries (e.g. corneal transplants, keratoplasty, corneal refractive surgery and laser surgery).
