The Impact of Blue Light and How Eyeglasses Can Help

The Effects of Blue Light

In our digital world, we often find ourselves bathed in blue light, a byproduct of the devices we commonly use like smartphones, laptops, and tablets. Continuous exposure to this blue light can have significant implications for our eyes. This article aims to explain the nature of blue light, why it’s important to our eye health, and how eyeglasses can aid in guarding our eyes against potential damage.

About Blue Light

Blue light forms part of the visible light spectrum, distinguished by its shorter wavelength and higher energy relative to other colors. The sun is a natural emitter of blue light, but it’s also significantly produced by artificial sources such as LED lights and digital displays. Due to the prevalence of these devices, we’re exposed to blue light constantly.

Understanding the Concerns of Blue Light

Blue light can potentially impact our health in several ways. Our eyes are less efficient at blocking blue light, which means almost all visible blue light passes straight to the retina. Studies suggest that extended exposure to blue light can lead to:

• Eye strain
• Dry eyes
• Headaches
• Blurred vision
• Fatigue
• Disturbed sleep cycles owing to decreased melatonin production
• Accelerated age-related macular degeneration
• Increased likelihood of cataracts

So as you can see, blue light exposure can have significant health effects. Some of the most significant effects, however, are on eye strain and sleep patterns. 

Blue Light and Eye Strain 

The scatter effect caused by blue light’s shorter wavelength makes focusing harder for our eyes. This scattered light creates a form of visual “static” that can lead to eye strain and discomfort, particularly after extended periods of exposure.

The Impact of Blue Light on Sleep

One of the most noticeable effects of blue light is its disruption to sleep patterns. Evening exposure to blue light, particularly from screen devices, can interfere with our natural circadian rhythm, thereby affecting the quality and onset of sleep.

How Can Eyeglasses Help? 

Thankfully, there’s a simple solution to protect yourself from blue light exposure: blue light eyeglasses. These glasses come with a unique coating that reflects and absorbs between 10% to 40% of blue light, shielding you from its adverse effects.

Those who have a significant screen time can particularly benefit from blue light blocking glasses. These glasses can help decrease eye strain and fatigue, and might even enhance sleep quality by minimizing blue light exposure during evening hours.

If you’re already using prescription eyeglasses, numerous opticians now provide the option of blue light protection as an added feature. This allows you to maintain clear vision and simultaneously guard against excessive blue light exposure.

A great source of blue light blocking eyeglasses is GlassesUSA. We offer a huge range of eyeglasses from great brands like RayBan, Oakley, and more. Plus, we offer blue light lenses on most of our prescription frames, so you can protect your eyes and look great doing it. 

Extra Perks of Blue Light Blocking Glasses

In addition to protecting your eyes, blue light blocking eyeglasses have several other advantages. They can boost your comfort during extended periods of screen time, enhance productivity and focus, and come in a variety of stylish frames, offering no compromise between fashion and protection.

The Link Between Blue Light and Sleep Patterns

Blue light can significantly affect our circadian rhythm, also known as our internal body clock. Daytime exposure to blue light can enhance alertness and performance, but evening exposure, like from screen usage before bed, can interfere with sleep. Blue light eyeglasses can help combat this, improving the ease and quality of sleep.

The Outdoor Impacts of Blue Light

Blue light isn’t limited to electronic devices; the sun is another significant source. Outdoor exposure to blue light can cause glare, reducing visibility. Blue light glasses can also be worn outdoors to decrease glare and improve contrast, enhancing visibility under various conditions.

The Protection Blue Light Offers

Blue light is everywhere in our modern lives, and it can present a number of potential issues. Eye strain, headaches, and issues sleeping are just a few of the effects of excessive blue light exposure. 

In our current times, blue light is an ever-present element that can lead to several potential issues, including eye strain, headaches, and sleep disturbances, among others. But the use of blue light blocking eyeglasses, such as those from GlassesUSA, offers a straightforward way to mitigate these effects. With their unique coating, these glasses can block up to 40% of blue light, thereby eliminating eye strain, headaches, and sleep issues.
