Eyes

As you'll soon discover, data seems to suggest that the blue light from smartphone screens has adverse effects on other parts of the body as well, or possibly, as you might not see. In 2018, University of Toledo researchers investigated subjecting cells to blue light with shorter wavelengths. Retinal, a substance secreted by the eyes, was found to cause harm to some tissues while leaving other tissues unaffected. Given that damaged photoreceptor cells cannot be repaired, this could be disastrous for the eyes' photoreceptor cells.
