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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
