Sitting for many hours staring at a PC screen can leave you feeling unfocused and tense. It can also cause you to experience a pounding headache that will make you feel irritated and tired. You will not experience these feelings just because a co-worker upset or frustrated you. Rather, they will most likely stem from something known as blue light.

 

What Is Blue Light?

The visible spectrum of light, which is what people see, consists of a wide range of colors. From red on the higher end to blue-violet on the lower end of the visible spectrum. The light on the lowest end has the shortest wavelengths, and vice versa for light on the highest end of the spectrum.

 

Interestingly, shorter wavelengths produce more energy, which is why blue light is a high-energy visible light. Blue light lenses aim to filter out this HEV blue light, thereby protecting your eyes. Most digital devices people use emit potentially dangerous blue light, which can penetrate to the back of the eyes.

 

Risks Associated with Blue Light

According to research, overexposure to blue light could lead to serious health conditions later in life. For example, it can cause age-related macular degeneration, which can lead to vision loss. When it comes to the potentially harmful effects of blue light exposure, kids are especially at risk. This is because their eyes are still developing and lack the protective pigments needed to filter out some of the blue light.

 

Blue Light Blocking Lenses

As digitization continues to take over the world, people are getting more and more blue light exposure. Blue light filtering lenses should block some of the potentially harmful high-energy blue light. This will help protect your eyes in the present as well as for the future. You need to understand that even the average light bulb can emit blue light. The largest source, however, is the sun, which produces enormous amounts of blue light.

 

Colors vibrate at different wavelengths when produced by something, such as a computer or television. Obviously, artificial blue light is nowhere near the strength of the blue light from the sun. However, people today spend so much time in front of different types of digital screens that even low emissions of blue light can start to build up over time.

 

The average adult in the U.S. spends the better part of the day staring at digital screens. As such, most people’s eyes are under tremendous digital light strain, according to ophthalmologists. Digital screen protection lenses aim to reduce the amount of eyestrain. They also aim to avoid circadian rhythm cycle disruption, which can affect your sleep.

 

Top Benefits of Blue Light Lenses

• They can help minimize the risk of age-related macular degeneration
   

• They can help you sleep better
   

• They reduce eye discomfort and eyestrain
  
   

Choosing the Best Blue Light Lenses

Blue light lenses block some of this blue light using a specially designed glaze that reflects it away from your eyes. The amount of blue light reflected away depends on the lenses you buy. Some of them are clear, while others come with a yellow tint. Those with a yellow tint tend to filter out more blue light. To find the best blue light lenses for your specific needs, however, you need to talk to an eye care professional.
