One of the major sources of blindness in the Western world is loss of the photoreceptor cells that capture light.
- One of the major sources of blindness in the Western world is loss of the photoreceptor cells that capture light.
- So when a photon, so when a little bit of light hits my eye goes in, the photoreceptors convert that into electrical signal, right?
- So you can, you can basically now start perceiving light and then perceiving shapes beyond just the sort of single photoreceptor.
- These IPRGCS don't, these new photoreceptors don't have these specialized structures.

Morphology
photoreceptor = receptor (semi-transparent) = photo + recept + or
The word is compositionally built from 'photo-' and 'receptor', but 'receptor' is a specialized technical base, so the meaning is only partly obvious to an average learner.
Etymology
Photoreceptor combines photo- 'light', as in photo or photograph, and receptor 'one that receives', so a photoreceptor is a cell in the eye that 'takes in' light and helps us see.
