Blue Light? What Is It And How Can You Protect Your Vision

Blue-light rays are found everywhere, most notably from the sun and from the light on devices such as tablets, computers, and cell phone screens. Blue light can have harmful effects on the eyes and cause worsening vision just like UV rays can, although you may not have ever been aware of it. You can protect yourself from blue light, but you have to know how. Read on for tips to protect your eyes from blue light.

1. Wear Sunglasses

Sunglasses can protect your eyes from the sun's harmful rays, as well as the blue light emitted by the sun. Look for sunglasses that say they protect against UV-A and UV-B rays, which can also protect you from blue light as well. Wear your sunglasses anytime you are in the sun; even on bright cloud-covered days you should be wearing sunglasses, as the rays from the sun can be peeking out from the clouds. Wearing a hat in addition to the sunglasses can also keep the rays out of your eyes and protect you from glare as well, which can strain your eyes.

2. Take Breaks From The Screen

Since blue light is emitted by the screens on computers, tablets, and cell phone screens, remember to take a break from these devices and look away from time to time to give your eyes a break and a chance to focus your vision on something else. Sometimes when looking at a screen for too long, it can cause other things to look different, or you may have a hard time getting your vision to focus on something further away. This type of strain can also cause your vision to deteriorate. Take a break from these types of screens throughout the day to give your eyes a break.

3. Keep Up With Your Vision Health

Be sure you are paying attention to any vision problems or to worsening vision and that you are going to the eye doctor for regular vision appointments to have your eyes checked. If you aren't going to the eye doctor at least once per year for a vision checkup, you could have vision problems and not treating them can lead to worsening vision and eye strain. Remember to make an eye appointment each year and wear whatever prescription your eye doctor prescribes you. Don't wear old prescription contacts or eyeglasses, as this can also cause vision damage. You can talk to your eye doctor about getting blue light lenses for your eyeglasses.

Make an eye appointment with your optometrist and discuss blue light, as well as how to protect yourself against worsening vision due to blue light. Visit websites like to learn more.
