Abstract Tear film flow and stability studies were carried out in patients suffering from herpes simplex keratitis and chronic blepharitis by performing Schirmer test I and tear film break‐up‐time (BUT) measurements. In herpes simplex keratitis the values of BUT were within normal limits. Values of Schirmer test I were significantly higher ( t ‐test, P < 0.001) in these patients and are considered to be due to reflex hypersecretion of tears. Schirmer test I was found to be unaffected, whereas the values of BUT seen were significantly lower ( t ‐test, P < 0.001) in patients suffering from chronic blepharitis. These lower values of BUT can perhaps be attributed to the altered resurfacing of precorneal tear film as a result of changes in the lid margins.
