Retinal Light Damage Through Prolonged Visible Light Exposure

Computers and laptops are increasingly used at work and at home. As a consequence, the exposure of short wavelength blue light, which is emitted by LED displays, increases too. By its action, light is well-known to enact damage on the neurosensory retina, especially on the underlying structures. In particular, this happens through photothermal, photomechanical, and photochemical mechanisms. This paper will point out what kind of medical, respectively pathological, changes within the eye happens and how much of visible light the eye can withstand before damage occurs.
