Abstract:
The retina is the neurosensitive layer of the eye. In this tissue, photoreceptors convert light into nerve signals to be relayed to the brain. Despite retinal specialization in the treatment of light, excessive exposure can cause retinal damage, called retinal phototoxicity. In recent years, lighting devices rich in wavelengths of high energy (blue light) appeared, raising new concerns about retinal protection against light damage. We focus here on light-induced ocular diseases and the possible influence on visual health of new lighting technologies.
