We wear sunglasses to protect our eyes from sunlight, but did you know digital screens can be just as damaging?
Blue light is short, high energy visible wavelengths that produce color in the light spectrum visible to humans. It exists in sunlight, and it illuminates our TVs, computers, laptops, smart phones, e-readers and tablets. With this excessive exposure to blue light, you are likely to suffer digital eye strain, headaches, physical and mental fatigue. And that's just the beginning! Overtime, the glare created on these screens may reduce your visual contrast, affect clarity and sharpness. 65% of American adults reported having symptoms of Computer Vision Syndrome, meaning permanent vision-related problems from extended use of digital devices.
Luckily even in our tech world, you can still take precautions to protect your vision. Follow these six steps for healthier eyes.
- The 20/20 Rule - Every 20 minutes, focus on something 20 feet away for 20 seconds
- Reduce competing light sources - Indoor light should be around 50% as bright as light found in most offices, don't sit in direct sunlight while using digital screens
- Take vitamin supplements - Omega-3/fish oil supplements are clinically proven to improve eye health
- Switch up surroundings to relieve visual fatigue - Take a break from your indoor light and walk outside as often as possible if you're using digital screens with artificial light
- Remember to blink - Staring at blue light sources can contribute to dry eye, as people forget to blink
- Get blue light blocking software - Change the color temperature of your devices to help reduce digital eyestrain and dry eye
Beyond eyesight, blue light has also been linked to the diagnosis of many sleep disorders because light tells our brain it isn't time to rest yet. And when we risk losing sleep, we risk many other areas of our health like being more prone to heart attacks, obesity, type-2 diabetes, and various cancers. So instead of falling victim to declining health, protect your vision. Take your Omega 3. And most importantly, give the devices a break.
