How Can Blue Light Blocking Glasses Help?

Nowadays, we are more exposed to blue light by using digital devices and gadgets; blue light blocking glasses  are necessary. Blue light is a part of the electromagnetic spectrum. However, the light in itself is not harmful. In fact, we can effectively tolerate the amount of blue light the sun creates.

But the problem occurs when we start exposing ourselves to more light. Our digital devices and Fluorescent bulbs often emit more blue light than necessary, resulting in eye damage. Hence, blue light-preventing glasses are essential even if you don’t have a vision problem.

What are blue light blocking glasses?

Blue light-blocking glasses are special glasses that block or filter out blue light emitted from digital devices, fluorescent bulbs, and the sun. The glasses, by their appearance, look like ordinary reading glasses you can wear in your everyday work. But they have a special kind of coating or tint that is said to reflect or block blue light from reaching your eyes.

Blue light can give our eyes detrimental effects that may affect our vision and sleep. So if you have an office job that requires you to work the entire day on laptop or desktop screens, experts suggest you should wear light-blocking glasses. But in what ways are they helpful? Let’s find out.

How do blue light-blocking glasses help?

Blue light is everywhere around us nowadays, and there is no other option to save us from this light than wearing a good pair of blue light-reducing glasses. Here’s how these glasses ensure you have healthy eyes.

Reduces eye strain

If you spend most of your day working in front of a digital screen, you may have experienced digital eye strain syndrome. Have you ever felt like you were watching your screen with closed eyes? This could be one of the symptoms of digital eye strain syndrome.

The problem can cause dryness, itchiness, and blurriness in the eyes. A good pair of blue light-preventing glasses can help deal with these eyes. When you use these glasses, you create a contrast in blue light being emitted from digital devices, thus giving yourself comfort and relief from eye strain when working.

Supports eye health

It’s not just an eye strain that blue light gives you. This spectrum of light causes various health issues to your eyes. Blue specifically can penetrate your retina cells and damage them. This can cause muscular degeneration, which leads to permanent vision loss.

This is one of the reasons why digital device users are more likely to get glasses. By protecting your eyes from prolonged exposure to blue light by wearing blue light filter glasses, you can ensure to keep your eye’s health intact.

Bring circadian rhythm to track

Blue light can disrupt our circadian rhythm. For example, when the sun emits blue light, it signals our brain to be in active mode to have the work done for the day. And when it sets, it signals our brain to have rest, which as a result, produces melatonin hormone, causing sleepiness.

When we expose our eyes to digital screens even after a night, this can give our brain the wrong indication, resulting in a disruptive circadian cycle. Even if you don’t work with a screen, you still might have this problem if you stay under more light for longer at night. Thus, you should wear blue light-blocking glasses to prevent your brain from taking false indications.

Helps with migraine caused by blue light

If your office work requires you to be in front of screens all the time, you might experience a headache at the end of the day. Prolonged exposure to these devices may lead to migraine, a severe headache where you feel pain behind your eyes, ears, and temples, see spots or light flashes, and temporary vision loss.

The migraine may result from blue light emitted from mobile or computer screens. The right pair of blue light-preventing eyewear can help you eliminate this problem.

Increase overall health

When your circadian rhythm is affected, it may cause problems with your sleeping cycle. As a result, you may not have enough sleep, which results in many mental and physical illnesses. Lack of sleep can affect your cardiovascular, metabolic, and immune systems and disrupt your mood and mental wellness.

Not getting enough sleep correlates with depression and other mental illnesses. Since blue light-blocking glasses can help you sleep well by blocking blue light, this can also lead to the overall health of your body.

Where should you wear blue light-blocking glasses?

Exposure to digital screens is inevitable, so blue light-blocking glasses are essential. Here are the places you must wear your blue light-reducing glasses to ensure you keep your eyes healthy.

At your workplace

You wear your blue light-blocking glasses while working on your laptop or computer. The blue light emitted from the screen is higher than the sun and may cause various eye problems. So expert optimists believe that wearing such glasses can help you get enough protection.

When taking red light flight

Sitting in a well-lit airport and about to take a red-light flight may be detrimental to your circadian cycle. In addition, exposing such an extent to blue light may disrupt your sleep cycle, which you don’t want right when you should be sleeping during your flight. So, in that case, you should put on blue light-preventing eyewear to ensure your eyes are protected against blue light.

In a room full of lights

Even if you don’t go out and don’t use digital devices, you still might be exposed to blue light. For example, if you are a homemaker, you get blue light exposure through LED or fluorescent lights in your home. So, it is also essential to have a pair of blue light-blocking glasses for women or men who take care of the home and do not spend most of the time in front of screens.

On streets with fluorescent bulbs

If you’re out on the street doesn’t mean you won’t get blue light in your eyes. Nowadays, as streets also have bright, illuminating bulbs, you may get exposed to blue light when out as well. So, ensure you also protect your eyes with glasses that block blue light, even when you are out chilling with friends.


Blue light-blocking glasses are an essential accessory you should have whether you work on a computer or not. This helps you prevent your chances of getting various eye health issues and keeps your eyes healthy and well-protected.
