Light is made up of a spectrum of colors that contain varying wavelengths and energy. Rays on the blue end of the spectrum, or blue light, have short wavelengths and more energy. They are naturally emitted by the sun and are generated by computers, televisions, and other digital devices.
Blue light has certain effects on your eyesight and on your general health. Here’s what your eye center wants you to know about blue light:
How Blue Light Affects Your Eyesight
Your eyes are not that effective at blocking visible light. In fact, most visible blue light can pass through your cornea and lens, easily reaching your retina. This is why exposure to blue light contributes to the development of digital eye strain. Also referred to as computer vision syndrome, this refers to the feeling of heaviness in your eyes after using your smartphones or watching on your laptops for a prolonged period. Using blue light-blocking eyeglasses can help manage this problem.
Moreover, your optometrist explains that studies have shown that the blue light reaching your retina can damage the light-sensitive cells in your retina. As a result, this causes changes in your eyes, leading to symptoms that resemble that of macular degeneration, which is an eye disease that can cause permanent loss of vision.
Blue Light and Its Effects on Your General Health
Despite the findings on the effects of blue light on your vision, blue light is not all bad to your health. In fact, it plays an important role in regulating your body’s sleep-wake cycle. Exposure to blue light, particularly the sun, during daytime keeps you alert and energetic. That said, using blue light-emitting devices at night, like your tablets or smartphones, can disrupt your sleep cycle, potentially leading to sleepless nights and fatigue during your waking hours.
