In this new normal era, we spend more time in front of the computer and other digital devices. Our obsession with electronic devices will continue in the future too. When you use electrical devices all the time, it’s important to know that a digital LED screen provides high-energy blue light. Although we get most of the same from the sun, eyes struggle to cope with that light.
Many studies have found out that overexposure to this light can harm our eyes, and it can interrupt our sleep schedule as well. One of the best ways to prevent this light is to wear glasses that protect the eyes. Here you must know that not all blue light preventing glasses are made equally, and they might not be effective as they are advertised. If you are concerned about the quality of the glasses you bought, then go through some tests before you make sure to return the product or keep it.
The human eyes can adjust 380 to 740 nanometers wavelengths. In the case of blue light, it has the shortest length but it has powerful energy which is called HEV or high energy visible ray. When you look at the sun, you won’t be able to stare at it for a long time, because it will not only hurt your vision, it can also cause damage. But you have to spend hours in front of your computer working and the blue light can still hurt your eyes without you knowing it.

There are some best ways to test blue light glasses. They are effective and you can do the tests easy to find out the best product.
Ask for Blue Light Glasses Spectrum report from the manufacturer. You can contact directly the manufacturer, and ask them for the spectrum report. This will show you the level of filter the glass can offer. If you are checking computer glass, it will have a clear lens and you can wear them in the daytime only, after sunset these glasses are useless. When the company sends you the report you have to check if the glasses can block at least 30% of the blue light of the entire range. You must avoid the company advertisement while checking the report. Also, ask the manufacturer company if the glasses block violet rays.
This is another solid test where you have to use a chart. You need to wear glasses and check the chart. If the glasses are filtering the light then the B section on the chart will look black and the G part will darken too. This shows that the glasses are filtering a section of green light, which is very crucial after sundown. If the green circle appears to be less bright then the glasses are of good quality.
You can also test your blue-light-blocking glasses at home. You just have to wear the glasses and check which lights are reflecting off the glass. If the blue one is reflecting off it, then it is filtering the same. If the reflection is purple or violet then you have to understand that it isn’t blocking the blue light perfectly. This is the easiest way of checking the blue light glasses are effective or not.
This is the safest and the best way to test your blue-light-blocking glasses. Here you have to use a lab-grade spectrometer. If the lights are purple or violet then the glasses are not blocking the blue light effectively. You have to know if the glasses can block the light after the sun is down. You can go for orange or red lenses, and ask for a spectrum report. If the red lenses aren’t blocking the entire blue light then return them, or refrain from buying them. If the glasses aren’t able to block 100% of the blue light at night time then it’s useless. You can also get access to a lab-grade spectrometer to check the glasses. The best way is to ask for the spectrum report before making the buying decision.
Buy blue light blocking glasses from a reliable seller or a manufacturer and you won’t have to worry about the efficiency of the product. Also, the seller or the manufacturer will offer you a spectrum report to earn the trust of their customers.
Blue light glasses are a type of eyewear that blocks blue light from entering your eyes. Blue light is the type of light that is emitted by electronic devices such as smartphones, tablets, and televisions.

The most common symptoms of blue light sensitivity are eye strain, headaches, sleep problems, decreased visual acuity, dry eyes, and blurred vision.
The protection of a pair of blue light glasses can be measured by the following factors:
– The type of blue light the glasses protect against.
– The level of protection that the glasses provide.
– The wavelength coverage.
– The amount or percentage of visible light transmitted through the lenses.
– Lens color and tinting.
Blue light glasses are not just eyewear. They are also a tool for managing your sleep cycle.
