What Are Blue Light Glasses?
Nearly every digital device emits blue light, a wavelength that’s been linked to a range of uncomfortable visual symptoms. Blue light glasses are designed to block blue light and help to keep your vision healthy. Many people choose to wear glasses with a slight magnification along with blue light blocking properties to further their comfort on a screen.
What is Blue Light?
Light is made up of multiple colored wavelengths, each with its own levels of intensity. Blue light is radiated from the sun but can also be found emitting from just about every digital device you come into contact with. Whether it’s your computer screen, tablet, or overhead fluorescent lights, you’re being exposed to this high-energy wavelength.
Exposure to blue light has been linked to eye issues and since most of us are on some type of digital device for most of the day, every day, it’s important to protect our eyes from this wavelength. Not only can blue light cause a variety of uncomfortable visual symptoms, but it is also linked to the disruption of our circadian rhythm, making it harder to fall asleep and causing our sleep to be less restful and restorative than it should be.
Do Blue Light Glasses Work?
Since we can’t visibly see blue light, many people wonder if blue light glasses actually work. These glasses feature tinted lenses — the most common color is amber although some people prefer to wear an orange tint instead. As blue lightwaves hit these lenses, the color of the lens allows other spectrums of light to pass through while blocking these blue lightwaves.
Blue light glasses work with and without a prescription and contribute to increased productivity, less eye strain, and can even help you to sleep better at night. It’s recommended that you wear them every time you use a digital device like a computer, watch television, or are under fluorescent lighting for long periods of time. It’s not necessary to wear blue light glasses when you’re engaging in other daily activities.
Types of Computer Screen Glasses
Amber Tinted Lenses
A popular option for computer glasses, amber lenses block blue light without darkening your vision. This tint absorbs blue wavelengths while allowing other wavelengths to pass through, providing you increased visual comfort while looking at a screen.

Orange Tinted Lenses
If you prefer a darker lens option for nighttime digital screen use, consider an orange-tinted lens. These glasses block more glare and blue light than amber lenses and are ideal for use after the sun has set, helping you to get a better night of sleep.

What Do Blue Light Glasses Do?
Our grandparents didn’t have to worry about overexposure to digital devices but in today’s world, it’s shocking just how many hours per day we spend looking at a computer, tablet, or television. This increased digital use means that we’re encountering blue light at a tremendously high rate, leading to sleeping problems and uncomfortable visual symptoms.
Blue light glasses help our eyes to relax and can prevent eye strain, headaches, blurred vision, dry eyes, and more. These lenses also work to keep our circadian rhythm operating correctly, as blue light can affect our melatonin production and cause us to have difficultly maintaining a natural sleep-wake cycle. When you wear blue light glasses regularly while using digital devices, you’ll enjoy increased productivity too!
What Devices Emit Blue Light?
Blue light isn’t inherently bad as it helps our bodies to maintain a natural sleep-wake cycle and can help to boost your mood, elevate reaction times, and more. Blue light itself is an important part of our wellbeing along with all of the other parts of the light spectrum. Overexposure to blue light, however, can be problematic, but do you know exactly where this wavelength of light can be found?
Not only does the sun radiate blue light causing the sky to become its beautiful ocean shade but a range of digital devices also emit blue light. Television screens, computer screens, and tablets and cell phones all give off this wavelength as well as LED or fluorescent lighting. That means that every time you check social media, answer an email, or spend hours gaming, you’re exposing yourself to blue light.
Should I get Computer Glasses?
In a perfect world, we would all use digital devices for a limited time each day and make sure our screens were set to Night Mode if we had to look at them after sunset. It’s not a perfect world, however, and we all spend hours upon hours looking at digital devices each day. In order to keep your eyes healthy and to maintain a proper sleeping cycle, wearing blue light glasses is key.
If you spend a lot of time on a computer screen, it’s also smart to wear computer glasses with blue-blocking properties. This slight amount of magnification can help to reduce eye strain, eye fatigue, headaches, and more. You’ll be more productive and won’t end the day with frustrating visual symptoms. Most people are surprised to find just how much computer glasses can help!
