- Reversible photochromics are also found in applications such as toys, cosmetics, clothing and industrial applications.
- Many inorganic substances also exhibit photochromic properties, often with much better resistance to fatigue than organic photochromics.
- This is particularly likely in compounds such as some photochromics, where A and B have entirely different absorption bands.
