Blue Light Explained Macular Degeneration Blue light (HEV) penetrates all the way to your retina and has been shown that too much exposure to blue light can damage light sensitive cells in the retina. This causes changes that are similar to those of macular degeneration, which can lead to permanent vision loss. When you're looking at your digital screen that emit significant amounts of blue light, this unfocused visual light reduces contrast and can contribute to digital eye strain. Sleep Disruption Blue light is very important in regulating circadian rhythm - your body's natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night can disrupt this cycle, causing sleepless nights and daytime fatigue. Why Not Block All Blue Light? It's well documented that some blue light exposure is essential for good health. In fact, something called light therapy is used to treat seasonal affective disorder (SAD) — a type of depression that's related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter. But too much blue light late at night (reading a novel on a tablet computer or e-reader at bedtime, for example) can disrupt this cycle, potentially causing sleepless nights and daytime fatigue.
