How can blue light glasses protect your vision?
LEDs are quite common these days as they are used in many devices and home appliances such as smartphones and computers. Since many people use cell phones these days and most of them sit in front of their computers for hours, we suggest wearing blue light glasses. Let’s find out how you can protect your eyes.
What is blue light?
Blue light is on the list of lights that have a higher energy wavelength. Digital displays, CFL / LED lights also produce a lot of this type of light.
The effects of that
Your eye has a sensor that detects whether it is day or night. Usually when these sensors are exposed to blue light, they can send a signal to your brain that it is daytime. Therefore, this wavelength is associated with the circadian rhythm. This is the cycle that can make your body feel alert or tired.
During the day, the blue wavelengths are quite beneficial as they can help you stay alert and give a better reaction. According to Harvard Health reports, this light can suppress your body’s melatonin secretion. This hormone is responsible for regulating sleep-wake cycles. Therefore, if you are exposed to this wavelength even at night, you can feel as alert as during the day. In other words, blue light can disrupt your body’s circadian rhythm.
Apart from this, it can also cause digital eyestrain. Since it has short wavelengths, it can be easily scattered. In addition, these wavelengths make concentration difficult, causing eyestrain.
Over time, blue light can have long-term physical effects, such as damage to the retina. Some wavelengths are associated with age-related macular degeneration or AMD.
Tips to reduce the effects of light
1. It is better to get plenty of sunlight during the day. Although it is contradictory, regular exposure to this light helps your brain with the circadian rhythm. What you need to do is protect yourself from harmful light and UV rays.
2. You can adjust the screen color of your devices, such as the LEDs of smartphones and computers. 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, do not use these devices when hitting the bed. Although it may not be easy for you to look away from your tablet or smartphone screen, you can at least put your phone aside at least half an hour before bed.
4. You can try blue light glasses as they are good for eyestrain. In addition, they can reduce glare, increase vision clarity, and reduce the likelihood of macular degeneration. Make sure the glasses don’t block the good turquoise blue light.
In short, this was the introduction to blue light glasses and how they can continue to protect your eyes. If you want to protect your eyes from light, we suggest you invest in a good pair of glasses.
