IT IS POSSIBLE TO HAVE TOO MUCH OF A GOOD THING!
Natural blue light from the sun boosts our immune system, makes us energetic and feeling happy but too much blue light, particularly the type emitted by screens on TVs, cell phones and computers can do damage to our eyes and our overall health. You and your family members probably spend time in front of those screens, unaware of how much blue light is being absorbed by your eyes, or that it causes health issues from digital eyestrain and headaches to disrupting your sleep cycle. Children are the most vulnerable to blue light, and we see them spending more and more time on devices for school, entertainment and communication. You can ask your optometrist about glasses with a blue light filter coating like Nikon SeeCoat Blue UV. The lenses will help filter the blue light and reduce the symptoms associated with blue light exposure.
