What are blue light glasses?

At present, we spend a lot of our time focusing on brightly-lit screens from morning to evening. Between our phones and laptops its hard to avoid a lot of screen time in our work and personal lives. But what are blue light blocking glasses and what do they do?

Digital screens are sources of artificial blue light. Blue light is a high-energy visible light. Blue light can affect your body’s circadian rhythm and biological clock as well as cause digital eye strain. Being exposed to blue light has been correlated to a range of issues people experience in their everyday lives.

That is where our glasses come in, but what are blue light blocking glasses? Do you want to know more about blue light and how it can affect you? Let’s have a look in closer detail about the effects and how our glasses may be of help.

What is blue light?

The visible light we see in everyday life is composed of an entire spectrum of the rainbow from red to blue. Blue light waves are part of that spectrum. They help you to stay alert and upbeat which we need in everyday life. Blue light accounts for one third of all visible light. In addition to this, it is the highest energy wavelength on the spectrum. However, an extended exposure to the blue light can lead to various problems.

Effects of blue light on eyes

More and more research is being carried out on growing screen times and how it is effecting our everyday well being. Recent research is focussing on increased blue light exposure and its links to digital eye strain.

Early research shows that when we are exposed to blue light for extended hours, we are more vulnerable to a myriad of problems. Some of the most common problems include:

1. Poor sleep

When the sun begins to go down, our bodies start to produce the hormone melatonin. This is the hormone responsible for making us fall asleep. However, more exposure to blue light can delay the production of melatonin in our bodies. Ultimately, you may experience problems in your sleeping pattern as your body’s circadian rhythm has been interrupted by this artificial light.

2. Eye strain

Sore or irritated eyes are one of the symptoms of digital eye strain. This can effect your focus in work or class. In addition to this you may experience dry eyes and fatigue.

3. Headaches

Symptoms such as a dull ache around the eyes and temples are a feeling many of us know too well. Studies have suggested that continuous exposure to blue light on a regular basis has the ability to lead to these types of headaches.

What blue light glasses can do to help?

Espy and Iris blue light filtering glasses are designed to filter out harmful blue light and prevent it from entering your eye. Our blue light lenses come up with a surface coating that block a certain percentage of blue waves.

  • Blue light blocking glasses are designed effectively to filter out blue waves emitted by our digital devices’ screens.
  • Blue light blocking glasses help with your sleeping pattern by improving melatonin secretion at the right times. Which in turn helps to regulate your body clock
  • These glasses help in reducing headaches and reduced digital eye strain.
