[Measurement of lens transparency in workers at risk of developing of glassblower's cataract].

The authors evaluated the transparency of lenses in persons on a stand predisposing to the formation of a glassblower cataract as well as in office clerks. They used for their measurements a fluorophotometer (Fluorotron Master) and an opacity lensmeter. In a group of 40 ironmasters they found a considerable fall in light transparency through the lens and a significant increase of the lens autofluorescence in comparison with a group of office clerks. The quantitative measurement of lens transparency by means of a fluorotron and a opacity lensmeter creates the possibility of an earlier detection of a ++pre-cataract condition.
