Effect of Blue Light.

Smart phones, laptops, and other handheld devices all transmit light. However, the blue light in particular may be toxic for your eyes.

Scientists at the University of Toledo may have discovered how blue light emitted from your technology has a potential to lead to macular degeneration — one of the leading causes of vision loss in the United States.

“It’s no secret that blue light harms our vision by damaging the eye’s retina” said Ajith Karunarathne, PhD, assistant professor at the University of Toledo’s department of chemistry and biochemistry in a released statement.

Macular degeneration is the result of photoreceptor cell death in the retina.

The function of the photoreceptor cells is to capture visual images and signal them to the brain using a molecule called retinal.

Retinal, which is produced by the eye, is triggered by blue light and causes various chemical reactions. These reactions within the eye can be poisonous to the photoreceptor cell molecules rendering them damaged.

When these photoreceptor cells die, there’s no regeneration.
