What Experts Say About Blue Light Blockers

As our society becomes more and more reliant on digital technology, the exposure to blue light emitted by electronic devices has become a growing concern. Blue light is a type of high-energy visible (HEV) light that has been linked to disrupted sleep patterns, eye strain, and even long-term vision damage. To combat these issues, many people have turned to blue light blockers as a solution. But what do the experts say about blue light blockers? In this article, we will explore the benefits, drawbacks, and effectiveness of blue light blockers according to industry professionals.

What Are Blue Light Blockers?

Before we dive into the opinions of the experts, let's define what blue light blockers are. Blue light blockers are glasses or lenses that are designed to filter out blue light emitted by electronic devices. They work by blocking certain wavelengths of light that can have negative effects on our eyes and overall health.

Benefits of Blue Light Blockers

Many people who use blue light blockers claim to experience a variety of benefits. According to Dr. Sabrina Shah-Desai, a leading ophthalmologist,

"Blue light filters can help reduce the symptoms of digital eye strain, such as headaches, dry eyes, and blurred vision."

Additionally, they have been shown to improve sleep quality by reducing the amount of blue light exposure in the evening, which can disrupt our circadian rhythms.

Drawbacks of Blue Light Blockers

While blue light blockers do have their benefits, they also have some drawbacks. One major concern is that they may not block all types of blue light.

"The quality of blue light filters varies greatly between different brands and models," says Dr. Shah-Desai. "Some may not filter out enough blue light to have a significant impact on eye strain or sleep quality."

Additionally, some people may find blue light blockers uncomfortable to wear or may experience distortion when looking at screens.

Foxleigh Blue Light Blockers have been designed to block the most harmful blue light and won't distort the screen as you view it. 

Effectiveness of Blue Light Blockers

So, do blue light blockers really work?

According to Dr. Cristina Schnider, an optometrist and vision scientist,

"There is some evidence to suggest that blue light blockers can be effective in reducing digital eye strain and improving sleep quality."

However, the effectiveness of blue light blockers may depend on the individual and the type of blue light being emitted.

"There are different types of blue light, and some may have more harmful effects than others," explains Dr. Schnider. "It's important to choose blue light blockers that are specifically designed to filter out the type of blue light emitted by your electronic devices."

Conclusion

In conclusion, blue light blockers have become a popular solution for people looking to reduce the negative effects of blue light exposure. While they do have their benefits, it's important to choose high-quality blue light blockers that are specifically designed to filter out the type of blue light emitted by your electronic devices. Additionally, it's important to remember that blue light blockers are just one tool to help reduce the negative effects of blue light exposure, and should be used in conjunction with other healthy habits such as taking breaks from screens and limiting screen time before bedtime.
