From your computer screen to your smart phone and television — blue light is everywhere. These devices are so common in our day to day lives that most people hardly give them a second thought. Sure, we know we probably shouldn’t spend so much time on our phones, but it can’t be hurting us, right? Wrong. All that texting and TV watching could actually be dangerous for your vision. The invisible light rays emitted from your tablet or phone may cause irreversible damage. This high-energy visible light, more commonly known as blue light, can have a variety of unexpected effects on your health.
To help you better understand how hours of screen time could be affecting your vision, here is your guide to how blue light may be effecting your vision:
What is blue light?
Without going into complicated physics, blue light is near the ultraviolet (UV) range of the visible spectrum. This type of light isn’t just limited to your handheld devices—it’s also found in natural sunlight and other light sources.
Blue light can actually be beneficial to you, as it can assist in regulating your natural sleep cycles and help you wake up without the help of an alarm clock. In addition, blue light can boost your alertness and improve your mood. While limited exposure to blue light is perfectly safe, many people use their devices for up to five hours a day, which is much more than the average eyes can handle.
Effects of blue light
Researchers and doctors do not know the long-term effects of extended blue light usage. But they do know that it can have a major impact on your day to day life. Not only can hours in front of the computer screen cause dry eyes, it can also result in sleep disruptions. You may also find yourself suffering from computer vision syndrome (CVS) after a long day at the office. This can include, eyestrain, blurred or double vision, headaches, physical and mental fatigue, difficulty focusing, dry eyes and neck or back pain. You may already suffer from a few of these symptoms without even realizing that it’s caused by your electronic devices.
Reducing the effects of blue light
Blue light is unavoidable in todays modern world. But there are ways you can help reduce your exposure and harmful effects of this type of light. Your optometrist in Cape Cod, MA recommends:
- Computer glasses: Computer glasses are a simple and cost effective way to reduce the effects of blue light. The glasses help you view the computer screen without the symptoms. Talk to an optometrist in Cape Cod, MA about getting a pair even if you wear contacts or don’t need prescription glasses.
