Tear pH: Hydrophilic lenses and the closed eye

Carney, Leo G. & Hill, Richard M. (1976) Tear pH: Hydrophilic lenses and the closed eye. International Contact Lens Clinic, 3, pp. 30-31.


On a previous study of tear pH and the unfitted eye it was found that prolonged eye closure (i.e. overnight) resulted in a significant shift in the acid direction in 22 of the 23 patients measured.1 With the advent of continuous wear regimens, does the added presence of a hydrophilic contact lens sigificantly affect tear acidity under prolonged closed eye conditions? Is there enough of an acid shift to alter the fitting or optical characteristics of a lens?

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
