Abstract:
Combining frozen section and scanning electron microscopy experiments to observe the cross section and surface state of the samples, this study finds an effective method to evaluate the location of dyeing materials of color contact lenses. Sixty samples were evaluated on their dyeing location statistically using this method. The results showed that there were only 7 lots of samples with their dyeing materials within their product. This method is effective in evaluating the location of dyeing materials for color contact lenses.
