Why is protection against blue light so important?
There are meanwhile indications that the mercury discharge or LED-based background lighting for flat screens (PC/TV) can lead to irreversible damage to the eyes. It is suspected that a high portion of blue light can have a damaging effect upon the macula. This could result in promoting age-related macular degeneration (AMD). Reduced contrast sensitivity, reduced visual acuity and a limited perception of color could be the consequences. High portions of blue light also negatively influence the hormone balance (stress hormones, melatonin). Red eyes, twitching eyelids, weariness, headaches, nervousness etc. are typical complaints with high portions of blue light from PC work or watching television.
