The average American spends around seven hours in front of screens each day. Digital devices have become a huge part of modern living. They are used not only for work but also for educational and entertainment purposes. In the era of digital advancement, the effects of blue light from screens on the eyes have become a topic of increasing interest and concern.
Continue reading to find out how blue light can affect your eyes.
Blue light is part of the visible light spectrum with the shortest wavelength and the highest energy. It usually comes from the sun but can also be produced from various human-made sources like digital screens and LED and fluorescent lights.
While many believe that blue light from screens can harm your eyes, there is no scientific evidence to prove this claim. You get even more blue light exposure from the sun than your digital devices. The blue light from screens is also not any more detrimental than blue light from the sun.
Moreover, the sun’s UV rays increase your risk of developing serious eye conditions, cataracts and eye cancer. That’s why experts highly encourage people to wear sunglasses when going outside during the day. Wearing a wide-brimmed hat can provide added protection from harsh UV rays.
It’s normal to experience discomfort after using a computer, tablet or smartphone for too long. You tend to blink less when facing screens, increasing the likelihood of eye strain and dry eyes. Fortunately, your eyes will feel better once you give them a break. Controlled exposure to blue light is known to have several benefits. It can elevate your mood, boost alertness and enhance cognitive function.
