Blue Light (High-Energy Visible) and Blue Light Blocking Glasses

The eye’s cornea and lens are unable to filter or deflect Blue Light. Photochemically-induced retinal injury is caused by the absorption of light by photoreceptors in the retina. Photoreceptors such as rod cells, cone cells & photosensitive ganglion cells convert light into electrical signals in the eye. Normally, when light hits a photoreceptor, the cell bleaches and becomes ineffectual until it has recovered through a metabolic process called Wald’s visual cycle. This visual cycle is the biological process which converts photons, such as electromagnetic radiation (UV light & Blue Light) into electrical signals in the retina. When the retina is
