According to an article published this past summer, Americans spend more than 10 hours per day in front of some sort of screen. Whether it is a phone, television, or computer, the truth is that 10 hours every single day of blue light exposure can be harmful to your eyes.


What is Blue Light?

Light travels in waves of electromagnetic particles which are measured by the length of each wave. The measurement used to measure a wavelength is called a nanometer, which is 1 1 billionth of a meter. Without delving into too much detail, the idea is the shorter the wavelength, the higher the energy. Each wavelength is described as a color such as green, yellow, red, and blue among others. Together these different colors make up the an electromagnetic spectrum. Blue light is part of the spectrum that is visible the human eye, or known on the spectrum as visible light. The wavelength for blue light is short, which means higher energy. Humans get most of their blue light exposure from digital electronics such as cellphones, computers, and television.

 

Why is Blue Light Harmful?

Because of the shorter wavelength, blue light contains higher energy. Studies suggest that with the amount of blue light exposure humans are experiencing, all of the energy can be harmful to the health of eyes and vision. The LED backlight technology used in digital electronics emits a very strong blue light, so it is pretty simple how long term use can mean negative impacts to vision health. Exposure to this blue light can also be one of the primary causes of digital eye strain and fatigue because of the amount of time spent staring at the screen.

 

How to Protect Your Eyes

Protecting your eyes from blue light exposure is vital to maintain good vision and eye health. While there are many temporary fixes like blinking more often and looking away from the screens every so often, there are also more beneficial ways to protect your eyes. At The Meadows Family Eye Care, we happy to offer a full line of bluelight blocking eye lens. Instead of allowing the wavelength to hit the eye, these lens reflect the wavelength away from the eye. These lens also provide a strain free experience when using a screen in low light scenarios.
