Blue-sensitive opsin is a protein that in humans is encoded by the OPN1SW gene. [ 5 ] [ 6 ] [ 7 ] The OPN1SW gene provides instructions for making a protein that is essential for normal color vision. This protein is found in the retina, which is the light-sensitive tissue at the back of the eye.

The OPN1LW gene ...
The opsin proteins currently in use have absorption peaks across the visual spectrum, but remain considerably sensitive to blue light. [76] This spectral overlap makes it very difficult to combine opsin activation with genetically encoded indicators ( GEVIs , GECIs , GluSnFR , synapto-pHluorin ), most of which need blue light excitation.
Panoramic night vision goggles (PNVG) increase FoV by increasing the number of sensor tubes. This solution adds size, weight, power requirements, and complexity. [69] An example is GPNVG-18 (Ground Peripheral Night Vision Goggle). [70] These goggles, and the aviation AN/AVS-10 PNVG from which they were derived, offer a 97° FoV. [68] Examples ...
The opsin is only activated when 11-cis-retinal absorbs a photon of light and isomerizes to all-trans-retinal, [16] [17] the receptor activating form, [18] [19] causing conformal changes in the opsin, [18] which activate a phototransduction cascade. [20] Thus, a chemoreceptor is converted to a light or photo(n)receptor. [21]
When George Wald discovered that rhodopsin is a holoprotein, consisting of retinal and an apoprotein, he called it opsin, which today would be described more narrowly as apo-rhodopsin. [14] Today, the term opsin refers more broadly to the class of G-protein-coupled receptors that bind retinal and as a result become a light sensitive ...
Extant vertebrates typically have four cone opsin classes (LWS, SWS1, SWS2, and Rh2) as well as one rod opsin class (rhodopsin, Rh1), all of which were inherited from early vertebrate ancestors. These five classes of vertebrate visual opsins emerged through a series of gene duplications beginning with LWS and ending with Rh1, according to the ...
