Are Blue Light Blocking Glasses Effective?

There are increasing concerns about the impact of digital screens on our eyes and how they affect our eye health. Although there isn't much evidence to support the claims that these glasses reduce eyestrain and provide protection in general, there are a few reliable studies beginning to show some promise. Let's begin with the basics.

 

What is Blue Light?

As the name suggests, blue light is visible light that falls at the "blue end" of the spectrum. The wavelength of blue light is shorter than the wavelengths of colors on the red side, so it hits our eyes with a lower frequency. While we are all exposed to blue light from sunlight, as well as other colors, prolonged exposure to "unnatural" blue light sources could cause eye damage.

 

Blue Light: Is it Harmful?

Blue light has been shown to disrupt melatonin levels in the body, causing sleep disruptions. While this helps us remain alert and focused during daytime, it can also interfere with our sleep.

 

What can blue light glasses do?

Blue light is emitted by all devices, including computers, TVs, smartphones, tablets, and phones. The blue light from the screens can signal our brain to stop producing melanin. Our sleep is affected if we don't produce melatonin. Your eyes block harmful blue light, which makes you feel more comfortable.

 

Are you able to wear blue light blocking glasses all day?

Blue light is a constant in our multi-screen world. This protective coating can be applied to any glasses with no side effects, even everyday glasses.

 

There are other ways to protect your eyes from blue light

• Avoid staring at bright screens for up to three hours before you go to bed.
• Wearing blue-blocking glasses is a good option if you work night shifts or use many electronic devices at night.
• You will be able to fall asleep at night if you get enough sunshine.
