When it comes to taking care of your vision, it’s important to understand how lights you interact with on a daily basis affect it. From being exposed to ultraviolet (UV) rays from the sunlight to blue light from your television or phone, your eyes can become strained and even damaged. The expert eye doctor at Northern Lights Eye Care in Anchorage, AK, explain how this common light affects your vision.

What Is Blue Light?

Simply put, blue light is in the shorter wavelengths in sunlight that has the highest amount of energy in the spectrum. This type is commonly found in the items you use every day—from cellphones to your television. The high-energy light is good for your health overall, but too much can harm your eyes.

How Does It Affect My Eyes?

While little UV radiation reaches the retina itself, visible blue light from devices goes directly past your cornea to your retina. Since people use devices that have blue light so often, too much exposure can cause vision loss, macular degeneration, or general eye strain.

Are There Ways to Protect Your Eyes?

There are various blue light filters that can help protect your vision; all you have to do is apply them onto screens that you used the most, like your cellphone or laptop. Protective eyewear is also made to help limit the exposure by using a yellow tint to block out the blue. Your eye doctor can help you find the best type of protection for your eye needs and lifestyle.
