As you know, staring into the light can cause eye damage. It’s why it’s a good idea to wear sunglasses on sunny days in California. However, that’s not the only source of light that can hurt your eyes. Light from electronic devices can cause eye damage as well. Although there are different types of light, blue light is one of the most common types that people are exposed to on a regular basis.
As such, you’ll want to make sure that you take precautions against any possible damage that blue light can cause to your eyes as a result of long-term exposure.
What is Blue Light?
Blue light is a type of light that is found in both natural and artificial light sources. Blue light has a shorter wavelength than other colors of light, and this is what gives it its name. The sun is the most well-known source of blue light, but it can also be found in fluorescent and LED lights. LED TVs, computer screens, tablet screens, and smartphones all emit blue light. In fact, any electronic device that emits light can be a source of blue light exposure.
How Can Blue Light Damage Your Eyes?
One of the most common problems that can be caused by blue light exposure is digital eye strain, which is caused by looking at digital screens for long periods of time. Symptoms of digital eye strain include difficulty focusing and irritated eyes.
A more severe problem that can be caused by blue light exposure is macular degeneration. This is a serious condition that can lead to blindness. Macular degeneration is caused by damage to the macula, which is the part of the eye that is responsible for central vision.
Ways to Protect Your Eyes From Blue Light
The following are a few tips to help protect your eyes against blue light damage:
- Decrease the amount of time spent staring at screens.
- Use screen filters to decrease your blue light exposure.
- Wear yellow-tinted or anti-reflective glasses to block blue light.
