What\'s that all about? Blue light is everywhere. It\'s in sunlight. But it\'s especially common in digital devices like iPhones, from the iPhone 8 and XR to the latest iPhone 12 Pro It\'s a modern-day menace Blue light penetrates your retinas, giving your brain a cue that it\'s time to wake up and seize the day. But extended exposure to blue light from an iPhone or other device can have a significant impact on our wellbeing - headaches, eye irritation and fatigue are all common symptoms of blue light exposure. Plus, by restricting the production of melatonin (a chemical which helps us sleep), blue light disrupts your natural sleep cycles causing you to feel lethargic, irritable and unproductive.
