Do I need blue light glasses?


Hey there, fellow screen-gazers! If you're anything like the majority of us you probably spend a significant chunk of your day glued to a screen. Whether it's your smartphone, laptop, or tablet, these devices have become an integral part of our lives. But with the increased use of screens comes a question: Do you really need blue light glasses to protect your eyes? In this blog post, we'll dive deep into the world of blue light and find out if you should be adding blue light glasses to your must-have list.

What is blue light?

Before we jump into the main question, let's first understand what blue light is. Blue light is a part of the visible light spectrum and has a wavelength between 380 and 500 nanometers. It is emitted by the sun, LED lights, and digital screens like smartphones, laptops, and TVs. Though it's not all bad (it can help regulate your sleep-wake cycle), too much exposure to blue light can lead to digital eye strain, sleep disturbances, and potentially long-term damage to your eyes.

The argument for blue light glasses

Blue light glasses have specially designed lenses that filter out or reduce the amount of blue light that reaches your eyes. By doing so, blue light glasses can help alleviate symptoms of digital eye strain, such as dryness, irritation, and fatigue. Additionally, wearing blue light glasses before bedtime can help improve sleep quality by reducing the disruptive effects of blue light on the sleep-wake cycle.

The science behind blue light glasses

While there's no denying the anecdotal evidence from happy blue light glasses wearers, the scientific community remains divided on the subject. Some studies have shown that wearing blue light glasses can improve sleep quality and reduce eye strain symptoms, while others have found little to no effect.

One thing to keep in mind is that the effectiveness of blue light glasses may depend on the individual. Factors like your natural sensitivity to blue light, the amount of time spent in front of screens, and the specific type of lenses you're using can all impact the results.

Do I need blue light glasses

So, do you really need blue light glasses? The answer, as you might have guessed, is that it depends. If you're already experiencing symptoms of digital eye strain or sleep disturbances and have tried other solutions without success, it might be worth giving blue light glasses a shot. But if you're not experiencing any discomfort or sleep problems, there's no pressing need to invest in a pair just yet.

Other solutions that can also help

If you're not quite ready to commit to blue light glasses, there are other ways to protect your eyes from digital screens:

1/ Adjust screen settings

Most devices have a built-in blue light filter or night mode that can help reduce blue light emissions. You can also adjust your screen brightness and color temperature to make it easier on your eyes.

2/ Take breaks

Practice the 20-20-20 rule. Every 20 minutes, take a 20-second break, and look at something 20 feet away to give your eyes a chance to rest.

3/ Adjust your workspasce

Ensure your screen is at a comfortable distance and angle, and use proper lighting to reduce glare and strain.
