Is blue light from digital devices causes damage to your eye?
When you stare at a screen for hours at a time, whether it is a computer, TV, phone or tablet, you are exposed to blue light from the device. But there is no scientific evidence that blue light from digital devices causes damage to your eye.
The best way to protect your eyes against eyestrain from blue light in devices is to take regular breaks using the “20-20-20” rule: Every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds. You can also use artificial tears to refresh your eyes when they feel dry.
