What Is Blue Light?
Blue light is a type of light with a short wavelength and high energy. It comes from the sun, but also from digital screens like phones, computers, and TVs. Because we spend more time on screens, our eyes get exposed to more blue light than ever before. Many people worry about blue light eye strain and digital eye health. Therefore, understanding blue light is important for protecting eyes from screens.
How Blue Light Affects Your Eyes
Blue light can pass through the front of your eye and reach the back, where the retina is. Over time, too much blue light may cause eye strain and discomfort. For example, staring at screens for long hours can make your eyes feel tired or dry. Some studies suggest that blue light might also affect your sleep by blocking melatonin, a hormone that helps you rest. However, more research is needed to know if blue light causes long-term eye damage. Still, it is wise to take steps for digital device eye care.
