How can blue light glasses protect your vision?

LEDs are quite common these days as they are used in many devices and appliances such as smartphones and computers. Since many people use mobile phones these days and most of them sit in front of their computers for hours, we suggest you wear 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 screens, 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’s 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, blue wavelengths are quite beneficial as they can help you stay alert and react better. According to Harvard Health reports, this light can suppress your body’s secretion of melatonin. This hormone is responsible for regulating sleep-wake cycles. Therefore, if you are exposed to this wavelength even at night, you may feel just as alert as you do 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 dispersed. Also, these wavelengths make it difficult to focus, leading to eye strain.

Over time, blue light can cause long-term physical effects, such as retinal damage. Some wavelengths are associated with age-related macular degeneration, or AMD.

Tips to reduce the effects of light

1. You’d better get enough exposure to 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 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, do not use these devices when you go to bed. Although it may not be easy for you to look away from the screen of your tablet or smartphone, 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. Additionally, they can reduce glare, increase clarity of vision, 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 the path they can take to protect your eyes. If you want to protect your eyes from light, we suggest you invest in a good pair of glasses.
