In its natural form, your body uses blue light to regulate your natural sleep and wake cycles. Blue light also helps boost your alertness, heighten reaction times, elevate moods, and increase the feeling of well-being.
Artificial sources of blue light include electronic devices such as cell phones, iPads, televisions, and laptop computers, as well as energy–efficient fluorescent bulbs and LED lights which all emit high levels of damaging High Energy Visible (HEV) blue light.
A Harvard Medical study states that, “HEV blue light has been identified for years as the most dangerous light for the retina. After chronic exposure, one can expect to notice natural sleep cycles disturbed, fatigue and headaches, along with a growth in the number of MACULAR DEGENERATIONS, GLAUCOMAS, and RETINAL DEGENERATIVE DISEASES.”
Protection for your eyes is available through special coatings applied to eyeglass lenses that absorb and filter the harmful HEV blue light and UV radiation while letting the beneficial blue light pass through.
