What Exactly Is Blue Light?
You may remember a little about electromagnetic waves from science class back at school. It is the magic behind wi-fi, radio, and even medical X-ray. Sound waves and visible light are also a part of the electromagnetic wave spectrum.
The thing that determines what an electromagnetic wave does is its frequency. The extremely high frequency of gamma radiation can damage living things. On the opposite end, low-frequency waves help you connect to your internet wirelessly.
Believe it or not, the color of light is also decided by its frequency. Within the spectrum of visible light, red has the lowest frequency. Blue light, on the other hand, has high energy waves, just slightly less powerful than UV waves. Blue light blocking contact lens or blue light filter contact lens are made to block this frequency.
Why Is Blue Light Dangerous?
The idea of light being a danger to our health is not new. We are often warned about the dangers of the sun’s ultraviolet light to our health. Ultraviolet light’s high energy waves can cause skin damage, premature aging, melanoma, and other types of skin cancer. Isaac Newton even temporarily blinded himself in an experiment by staring at the sun with one eye.
The electromagnetic energy of blue and violet lights is not as powerful as UV waves, but only just. Experts think that blue light is responsible for many common health issues.
Blue light can disrupt the production of melatonin which regulates our sleep. It has also been linked to retinal phototoxicity whereby our retinas are damaged by light. In fact, high exposure to blue light has even been linked to the development of cancers. Many people choose to wear blue light filter glasses or contact lens to protect themselves from these dangers.
How Are We Exposed to Blue Light?
Blue light comes from a variety of sources. Most of the blue light we receive actually comes right from the Sun. However, we don’t spend our days staring at the Sun like Isaac Newton. In fact, for the modern person, there is a possibility that we are getting not enough Sun exposure. LED light bulbs produce a fair amount of blue light compared to incandescent or even fluorescent light.
However, the most worrisome sources of blue light are the screens we stare at night and day. You are likely reading this article on one of the blue light emitting screens. Whether it’s your smartphone or your tablet or even your computer, your devices are constantly shining blue light straight into your eyes.
You may have experienced eye discomfort or vision problems after viewing a digital screen for hours on end. 65% of Americans report experiencing computer vision syndrome. For most of us, it is simply impossible to live our lives screen-free. And this is especially true during the Covid-19 pandemic when need to communicate through virtual means.
Blue light blocking glasses are designed to filter out most blue lights from entering your eyes. This can help reduce the potential damage blue light poses to the eyes. While research on blue light blocking glasses is still new, one by the SPIE suggests that blue light filtering lenses may reduce computer vision syndrome.
If you cannot avoid prolonged screen time, these blue light glasses, along with good eyecare habits and techniques may alleviate your symptoms. These glasses can give you the peace of mind to work, play, and connect safely and comfortably.
