The Importance of Healthy Vision on National Video Games Day
Are you noticing that your eyes are feeling dry, sore or just uncomfortable after staring at your screen all day? We’ve got news for you! The blue light emitted from your devices – your computer, tablet, tv or cell phone – can be harmful to your eyes. Here’s why and what to do for healthy vision.
What is Blue Light?
Most of us are using a device that emits blue light throughout the day, with studies suggesting that 60% of people spend more than 6 hours a day in front of a digital device.
According to BlueLightExposed.com, blue light waves are among the shortest, highest energy wavelengths, causing flickers that create a glare that have been shown to reduce visual contrast and affect sharpness and clarity. “This flickering and glaring may be one of the reasons for eyestrain, headaches, physical and mental fatigue caused by any hours sitting in front of a computer screen or other electronic device.” LED black-light technology – including TVs, computers, laptops, smart phones and tablets – help enhance screen brightness and clarify, emitting very strong blue light waves.
What to do
There are a few things you can do to protect your vision against these harmful blue light rays.
- Reduce the glare of your device by reducing its brightness. If you are on the computer for long periods of the day, you may want to invest in a glare reduction filter for your screen.
- Increasing the text size on your devices may help to protect against eye strain.
- Take a break every 20 minutes for your device!
- Limiting your screen time is the most effective.
Natural Support for healthy vision
In our retina, an essential region for crystal clear vision, the concentration of two carotenoids – Lutein and Zeaxanthin (abbreviated L + Z) – are essential for ongoing vision health. They are so important to vision that they are commonly referred to as macular pigments. The macula is a filter that helps protect the eye.†
Healthy, robust macular tissue, rich in L + Z, has key functions, including filtering out blue light and focusing on objects for our sharpest vision (such as in reading a newspaper). If it penetrates deep into our eyes, it damages the many small organs in our retina that are required for vision. Having a thicker macular tissue shields from blue light and this robustness is largely due to its L + Z content.†
