Blemishes developing on soft contact lenses.
Suspected contamination of soft contact lenses lead to biological, X-ray spectrophotometric, and photographic investigations to attempt identification of substances which could not be cleaned from the lenses and which increased in number with time. All indications point to suspect contaminant not being foreign material but a breakdown of the polymer structure.
