Dry. Irritated. Tired.
Digital eye strain includes blurry vision, difficulty focusing, dry and irritated eyes, eye fatigue, and that drained feeling after hours at a computer.
Effects of Blue Light
10 HOURS A DAY.
Protect your eyes from blue light.
High Energy Visible (HEV) blue light emits from digital devices and electronics like LED lights, TVs, computers, phones, and tablets. Its shorter wavelength scatters more, decreases contrast, and strains the eyes.
Headaches and migraines.
Harsh screen light is a leading cause of migraines, headaches, eye fatigue, neck discomfort, and back pain.
Your circadian rhythm gets hit.
Nighttime blue light disrupts the pattern that tells your body when to sleep, affecting rest, cognitive functioning, and next-day performance.
What is blue light?
Blue light is part of the visible light spectrum. High Energy Visible blue light has a shorter wavelength than other visible light, causing it to scatter more, decrease contrast, and strain the eyes. Your laptop, desktop monitor, phone, tablet, TV, LED lighting, and the sun all expose you to it.
What is digital eye strain?
Digital eye strain due to blue light exposure is a medical issue with serious symptoms that can affect learning and work productivity. Symptoms include blurry vision, difficulty focusing, dry and irritated eyes, headaches, neck pain, and back pain. Digital eye strain has overtaken carpal-tunnel syndrome as the number one computer-related complaint—so it's time we do something about it.
What happens to the eye and retina?
Blue light damages the eye and retina through photo-oxidation and accelerates macular degeneration. Short-term exposure can produce digital eye strain. Long-term chronic exposure can impact central vision.
What does blue light do to sleep and long-term health?
Blue light affects the Retino-Hypothalamic tract, which regulates circadian, endocrine, and neurobehavioral functions. Nighttime blue light disrupts the circadian pattern, leading directly to sleep deprivation and indirectly relating to cancer, cardiovascular disease, hypertension, depression, diabetes, and obesity.
When should you protect your eyes?
During computer work, video calls, phone use, digital reading, TV, and evening screen time. Clear blue light glasses help protect your eyes and reduce eye strain.
“The impact of naturally occurring Blue Light has been overlooked for many years; however with increased exposure to artificial Blue Light from high energy efficient light sources including fluorescent lighting and LED screens, medical scientists are recognizing Blue Light can have profoundly negative effects on human health.”
