According to Popular Science, blue light being emitted from phone, tablets, computer screens, etc. has been associated with disrupted circadian rhythm in the body and for a long period of time, doctors and scientists have been focused on researching the connection between this light and eye-related issues, including eye strain, glaucoma, and macular degeneration.
Let us learn more about why we need to minimize our exposure to the blue light being emitted from screens and how to achieve that best.
Why Blue Light Is not Good for Our Eyes?
As explained on Healthy Holistic Living, as humans, we see a thin light spectrum which ranges from red to violet color and the longer wavelengths appear red while the shorter ones appear blue. It is important to note that you may consider the light from a screen as white; however, it is a combination of colors that you cannot see. And, research indicates that blue light (445-nanometer shortwave light) can cause a serious damage on the cells in the eyes.
When they are exposed to blue light, they encourage oxidation, a chemical reaction happening in the eyes and due to being energized by the blue light, the retinal destroys photoreceptor cells which cannot grow back again once they are injured. This eventually elevates your risk of macular degeneration, blurry vision, and blindness.
How to Keep Your Eyes Safe from the Blue Light?
Taking into account that that we spend most of our time in front of a computer or smart phone screen because of work or fun, it is good to know how best to protect our eyes from the blue light as most of us cannot entirely exclude them from our lives. Check out some beneficial tips below that we discovered on Healthy Holistic Living.
And, excessive sun exposure can also worsen the health of your eyes, therefore, whenever you head out, put on blue-light filtering and high quality sunglasses. When it comes to screens, decrease the light to ambient settings and wear protective eyewear. Consult your ophthalmologist for the best eyeglasses for you that will keep the eyes safe from the harmful light.
Remember, blue light is also released by regular light bulbs you probably have in your home. If possible, replace them with highly-efficient LED bulbs or amber light bulbs.
