Contact lens dosimetry of solar ultraviolet radiation

McLaren, Ken, Watson, William, Sanfilippo, Paul, Collins, Michael J., Sydenham, Michael, & Hirst, Lawrence (1997) Contact lens dosimetry of solar ultraviolet radiation. Clinical and Experimental Optometry, 80(6), pp. 204-210.


Background: Ultraviolet radiation from the sun has been implicated in the pathogenesis of many ocular conditions. However, the amount of UV reaching the eye is not well defined. Methods: A contact lens made from the UV-sensitive plastic polysulphone was used to measure the dose of UV radiation at the surface of the eye for two subjects over six wearing trials. Results: The average ratio of UV radiation exposure at the surface of the eye to that of the UV radiation in the surrounding environment (ambient dose) was found to be 28 ± 9 per cent. The temporal UV dose appeared lower than both the central and nasal UV doses in five of the six wearing trials but these differences did not reach statistical significance. Conclusions: Contact lenses made from polysulphone can be used to estimate the regional dose of solar ultraviolet radiation.

Search Google Scholar™

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.
