Coenzyme Q10 in the eye isomerizes by sunlight irradiation
Scientific Reports, 2022 Photoisomerization of lipids has been well studied. As for the eyes, photoisomerization from 11-cis isomer to all-trans-retinal is well-known as the first step of the visual transduction in the photoreceptors.

Role of Thr82 for the unique photochemistry of TAT rhodopsin
Biophysics and Physicobiology, 2021 Marine bacterial TAT rhodopsin possesses the pKa of the retinal Schiff base, the chromophore, at neutral pH, and photoexcitation of the visible protonated state forms the isomerized 13-cis state, but reverts to the original state within 10–5 sec.

Structural Evidence of Photoisomerization Pathways in Fluorescent Proteins [PDF]
, 2019 Double-bond photoisomerization in molecules such as the green fluorescent protein (GFP) chromophore can occur either via a volume-demanding one-bond-flip pathway or via a volume-conserving hula-twist pathway.
