Effect of blue light on Albino Rat's retina

Background: Blue light has a very dangerous and harmful effect on the retina. Blue light is part of electromagnetic radiation and has wavelength in-between 400: 500 nm. Blue light affect retina through different mechanisms and causes blue light hazard. It affects mainly people having longtime on smartphones and TVs. It also causes eye strain, corneal damage, lense damage, migraine and sleep disorders. Aim of the work: To study the effect of blue light on albino rat’s retina. Methods: Thirty rats were divided equally into two groups: C-group (control group) and B-group (blue light exposure group). Measurement of retinal malondialdehyde (MDA) and histological approaches were done. Results: B-group showed significant increase in MDA levels and had retinal thinning with degenerative changes as loss of some retinal cells and layers and disorganization of normal retinal arrangement. Conclusion: Blue light had an apparent damaging effect on retinal tissue.
