LEDs are quite common these days as they are used in a lot of devices and appliances, such as smartphones and computers. Since a lot of people use mobile phones these days and most of them sit in front of their computers for hours, we suggest that they use blue light glasses. Let’s find out how it can protect your eyes.
What Is Blue Light?
Blue light is on the list of lights that have a higher-energy wavelength. Digital screens, CFL/LED lights also produce a lot of this type of light.
The effects of it
Your eye has a sensor that detect whether it’s day or night. Typically, when these sensors are exposed to blue light, they can send a signal to your brain that it’s day. Therefore, this wavelength is associated with the circadian rhythm. This is the cycle that can make your body feel alert or tired.
During the daytime, blue wavelengths are quite beneficial as they can help you stay alert and give better reaction. According to the reports from Harvard Health, this light can suppress the secretion of melatonin from your body. This hormone is responsible for regulating the sleep-wake cycles. Therefore, if you are exposed to this wavelength even at night, you can feel as alert as you are during the day. In other words, blue light may disrupt the circadian rhythm of your body.
Aside from this, it may cause digital eyestrain as well. Since it has short wavelengths, it can scatter easily. Plus, these wavelengths make it difficult for you to focus, which causes eyestrain.
With the passage of time, blue light may produce long-term physical effects, such as retina damage. Some wavelengths are associated with age-related macular degeneration or AMD.
Tips to reduce the Effects of the Light
1. It’s better that you get enough exposure to sunlight during the daytime. Although it is counterintuitive, the regular exposure to this light helps your brain with the circadian rhythm. What you need to do is protect yourself from the harmful light and UV.
2. You can adjust the screen color of your devices, such as smartphone and computer LEDs. If your screen doesn’t allow you to make these changes, you can use a special app like Night Shift and Twilight.
3. If possible, don’t use these devices when you are going to hit the bed. Although it may not be easy for you to keep your eyes off the screen of your tablet or smartphone, you can at least put your phone aside at least half an hour before bedtime.
4. You can try blue-light glasses, as they are good for eyestrain. Plus, they can reduce glare, boost vision clarity and reduce your likelihood of macular degeneration. Make sure that the glasses don’t block the good blue-turquoise light.
In short, this was the introduction to blue light glasses and the way they can follow in order to protect your eyes. If you want to protect your eyes from light, we suggest that you invest in a good pair of glasses.
