5 Things To Know About Blue-light


For many years now, technology and the digital world have become an integral part of our lives. Each day we are surrounded by hundreds that are constantly requesting our attention. Whether it is our laptops, work computers, tablets, smartphones, televisions, ordering food, or even watches, we now live in a world where digital screens can no longer be ignored.

Because our lives have been over time evolved into the gradual adaptation and adoption of technology in its various forms, we are now more than ever, exposed to new risks that were once not even imaginable. One of those risks is the effect of blue light on our eye care.

What is Blue light?

Among the 7 different colors that exist in the visible light spectrum, Blue light is one that is characterized by high concentrations of energy and short wavelengths.  Up until recently, the main source of blue light in our world was the Sun. Through it, we are exposed to a type of blue light that is considered natural. On the other side of it exists a type of blue light that is emitted by our digital screens.

Most of today’s electronic devices actually use LED back-light technology which enhances screen brightness and clarity but also emits strong blue light waves. And while blue light is beneficial in many ways, it can also have numerous negative effects on our health. Especially when exposed to it for a long period of time.

Digital eye strain

Blue light, due to its shorter yet higher energy wavelengths, flickers more easily than lights with weaker wavelengths. This type of flickering actually creates a glare that can reduce visual contrast, thus affecting sharpness and clarity. And because our eyes are currently not equipped to filter this type of light, any long exposure to such flickering can, therefore, cause something known as digital eye strain. Some of its symptoms include dry, sore, or irritated eyes, blurry visions, and headaches. 


Thousands of people suffer from frequent insomnia and other sleep conditions. As part of short-term treatments, many of them are advised to use melatonin, which is a hormone that our body normally produces. Melatonin is believed to improve sleep patterns by regulating the body’s temperature, blood pressure, and hormone levels. It supports the body’s circadian rhythm. In fact, natural blue light is also known to impact the body’s circadian rhythm. However, when night falls, chronic exposure to blue light will instead reduce the production of melatonin, thus disrupting the circadian rhythm and causing sleeplessness.

Retina damage

Although many studies are still trying to verify the effects of blue light on the eye, especially in the terms of how much blue light exposure will/can damage our visions, blue light, as a result of its penetration in the retina, can actually accelerate a condition known as age-related macular degeneration (AMD). This condition is often characterized by a blurriness in the center of one’s vision.

Why you need blue light filter glasses

Up until 2019, on average, adults spent about 11 hours on a screen, as compared to teens who spent about 7 hours. But while those stats must have been consistent then, because of the Coronavirus pandemic that is currently affecting our entire planet, screen time has definitely increased.

The majority of businesses and individuals have shifted to the digital and remote world. This means that we are now much more exposed to blue light and its effects than we ever were. For this reason, one would say that it is necessary to invest in better custom eyewear Westminster co to protect both ourselves and our families.

Blue light filters and protective eyewear

If you are using your phone constantly — especially if you use it primarily for texting, emailing and web browsing — a convenient way to reduce your blue light exposure is to use a blue light filter. Digital electronic devices emit blue light that can cause eye strain and may lead to eye problems over time.

These filters are available for smartphones, tablets, and computer screens and are available wherever electronics are sold, and sometimes there’s even a setting built into the device. 

Blue light filters reduce the amount of blue light emitted from these devices from reaching your eyes without affecting the visibility of the display. Some are made with thin tempered glass that also protects your device’s screen from scratches.
