Photochemical reaction | chemical reaction | Britannica.com
Photochemical reaction: Photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules. These new chemical

Photochromism - Wikipedia
Photochromism is the reversible transformation of a chemical species between two forms by the absorption of electromagnetic radiation (photoisomerization), where the two forms have different absorption spectra. Trivially, this can be described as a reversible change of colour upon exposure to light.

Steroids. If you must take steroids, we recommend that you also take the Advanced Eye & Vision Support Formula to protect your vision.; Steroids, such as Glucocorticoids (Prednisone), are photosensitizing drugs (drugs that increase your sensitivity to the sun) and undergo a photochemical reaction resulting in chemical modification of tissue.
Sherwood Scientific Ltd
PRINCIPLES OF METHOD The main difficulties with the classic method were that silver nitrate reagent would change on storage due to a photochemical reaction and that the titration end point is visually weak.

LUXIDUM | Vitamin D Mushrooms › LUXIDUM
Dr. Paul Urbain is a pioneer in the field of “Vitamin D Mushrooms” research. As a nutritional scientist, he was in 2011 the first to demonstrate in humans that the bioavailability of vitamin D from UV-treated and vitamin D-rich button mushrooms can effectively cure vitamin D deficiency .
