Blue light glasses with the proper lenses may help you sleep better at night. To find a pair that works, look for one that filters out the most melatonin-disturbing light.
This post will teach you how to test blue light and computer glasses. It will show you how to determine whether you have the best blue light computer glasses and if they perform correctly.
Why should you use a blue light glasses test?
To test blue light glasses, you must first understand the melatonin disturbance zone and do a simple blue light test.
You may conduct several fast and simple at-home tests to determine if your glasses provide comprehensive blue light protection. Everything in this post intends to help you efficiently regulate your exposure to blue light.
Blue light glasses are several types of blue light filtering lenses.
There are several blue light filter lens colors. Therefore, it is critical to understand the varying performance and clarity these will provide and when they are appropriate for usage.
Here is an overview of each choice and everyday use scenario, with hues ranging from clear translucent glasses to deep red.
1. Clear lenses for computer glasses
As the name implies, these blue light glasses are designed to be worn while working on a computer or smartphone or watching television.
Their function is to relieve digital eye strain and to filter off light rays at the beginning of the blue light spectrum.
The finest computer glasses filter between 25 and 30 percent of all blue light.
2. Yellow lenses for night driving glasses
When driving at night, yellow-blue light filter glasses are recommended.
Compared to clear lenses, they are better at eliminating more of the highest intensity blue light, approximately 440 nm, while remaining clear enough to discern traffic signals and drive at night.
With more and more automobiles equipped with LED lighting, this style of blue light glasses is highly suggested for night driving.
When tested using a blue light test, they usually block 65-70% of blue light.
It implies that this color lens fails to filter out the blue light that significantly impacts your sleep hormone (460–480 nm).
3. Blue light glasses with orange lenses for better sleep
Orange lenses are used in the finest blue light glasses for sleeping. A well-balanced sleep lens filters out 100% of the most melatonin-disturbing light while remaining clear.
4. Blue light-blocking sleep glasses with red lenses
Red lenses are touted as being better for improving sleep than orange lenses.
The problem with these deep dark red lenses is that they are challenging to see through while providing minor sleep benefits compared to orange lenses.
5. Risk Factor
They risk causing extra strain on your eyes, similar to wearing sunglasses inside when your eyes must work hard to see anything. Most of the additional light filtered out is in the safe yellow, orange, and red spectra.
Red lenses may filter out the same amount of blue light as orange lenses, often 99.5-99.9% of the time.
As shown in this article, it is simple to determine the effectiveness of your blue light-filtering glasses in blocking out blue light.
Regarding green light filter performance, testing using a lab-grade visual spectrometer and a standardized full-spectrum light source is the only way to acquire a trustworthy result.

Who Needs Blue Light Protection Lenses?
Blue light is everywhere – Artificial blue light sources include fluorescent and LED lighting, flat panel TVs, computers, electronic notebooks, smartphones and screens of other digital devices. Our main source of blue light is the sun, and we are most exposed to it when we are outdoors during the day. Children are also vulnerable because they tend to spend a lot of time outdoors.
Most of us tend to spend at least a few hours a day staring at our phone or computer screens, but the need for blue-light-blocking lenses increases for the following groups of people:Working Professionals – Simple jobs that require you to work on a laptop or PC from 9 to 5, 5 days a week can expose your eyes to a significant amount of blue light.
Professionals should definitely use blue light protection glasses.
Gamers – Playing together for hours online without blinking for a few minutes can put a lot of strain on your eyes given the amount of blue light your eyes are exposed to.
Binge Watcher – Watching your favorite series or movies can keep you glued to your TV or mobile girlfriend device for hours. Before you know it, your eyes are absorbing a lot of blue light. To prevent this, you need blue light blocking glasses.
Students – Today’s online classes require students to rely entirely on their digital devices to study and revise long hours of class. It’s a similar story to children who seem to want to spend most of their day playing games on their phones and tablets. Such students and children should use anti-blue light glasses to protect their eyesight.
However, we have to come back to the fact that the blue light that the sun emits is the most powerful and most likely to harm us. Therefore, simply protecting your eyes from artificial light sources is not enough. For protection, lens coatings should be used to filter out harmful blue light and let in good light.This can provide lasting protection for your eyes without compromising your vision. Clear protective lens coatings like Crizal are perfect for both indoor and outdoor use and offer a practical solution to harmful blue light. indoor and outdoor Another effective method is to use photochromic lenses. This is clear in low light, but darkens as the light increases.
Transition lenses provide optimal protection from harmful UV rays from the sun and blue light from digital devices and home lighting. These glasses are suitable for wearers of all ages and are a clear advantage for children under the age of 12, who are more susceptible to sun damage as their natural protective barrier for their eyes is still underdeveloped.
