WebSep 20, 2024 · The ipRGCs exhibit their peak sensitivity at 480 nm. There is some evidence that patients with blepharospasm reported the best relief of photophobia with the FL-41 lens, which blocks wavelengths around 480 nm [ 55 ]. The use of dark sunglasses indoors must be strongly discouraged. WebJul 6, 2016 · Melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs, with five subtypes named M1–M5) are a unique subclass of RGCs with axons that project directly to many brain nuclei involved in non-image-forming functions such as circadian photoentrainment and the pupillary light reflex. Recent evidence suggests that …
