Facts About Blue Light | Everyone must know!

Did you know that digital gadgets emit a small amount of blue light compared to the quantity produced by the sun? The light that the human eye perceives is a complicated phenomenon. As you are undoubtedly aware, sunlight generates both visible and invisible ultraviolet (UV) radiation, which can cause damage. However, an entire range of light wavelengths collectively makes up what humans perceive as white light. If you want to get rid of blue light, you can order blue-light-blocking glasses online at affordable prices. 

According to the facts, blue light provides the greatest energy since it has the shortest wavelength within the white light spectrum. While sunlight is the primary source of blue light, we are constantly in contact with artificial sources. After all, our contemporary houses are densely packed with electrical equipment that generates this light. We've delved further into the science of blue light to distill the essentials and provide you with complete facts.

How do you define blue light? 

A part of the electromagnetic (EM) spectrum generates signals and perception in the human visual system. This portion is referred to as "light," whereas the non-visible portions of the electromagnetic spectrum are frequently known as "radiation," for example, ultraviolet or infrared radiation. The visible spectrum extends from around 380 nm (blue-violet) to approximately 780 nm (red). Blue light is the portion of the visible light spectrum with the shortest wavelengths, ranging from 380 to 500 nanometers. In addition, blue light is close to and partially overlaps with the ultraviolet (UV) radiation spectrum, with even shorter wavelengths (100 nm – 400 nm).

What material are blue light Blocking glasses constructed of? 

Let's take a closer look at three distinct blue light glasses. Clare blue light blocking glasses have lenses composed of CR-39, a kind of plastic polymer (resin). The material is naturally scratch-resistant and filters off a significant portion of the ultraviolet spectrum. Glasses are further classified into two categories: biodegradable plastic frames and standard metal frames.

Can blue light cause eye damage? 

Research in the life sciences has accumulated an indisputable amount of data demonstrating the dangers of UV radiation to human health and biological cell damage. This is true for both the skin and the ocular tissues. By physical principles, the wavelength of electromagnetic radiation is proportional to its photon energy. Photon energy is the source of potential cellular and molecular damage. 

While scientific research indicates that blue light can initiate metabolic processes that might eventually result in long-term deterioration of cell integrity and premature cell death due to photo-oxidative stress, the damage cues discovered for the ocular, namely the retinal components, are multiparametric dangers. And, because the repercussions are long-term in nature — decades rather than years – it is difficult to demonstrate correct causation.

It adds to the development of digital eye strain.

Almost 70% of individuals who routinely use media devices have experienced some symptoms of digital eyestrain. Digital eyestrain is a significant medical issue that can impair learning and job efficiency. Blurred vision, difficulty focusing, dry and irritated eyes, headaches, and neck and back discomfort are symptoms. Digital eyestrain has surpassed carpal tunnel syndrome as the most often reported computer-related ailment.

Contrast is substantially increased when blue light blocking glasses are used. If you spend more than seven hours a day in front of a media device, using blue light glasses with yellow-tinted lenses may improve your comfort and prevent eye damage.

The hue of the light is critical to the health of your plants. 

One of the fascinating blue light facts for gardening lovers is that the hue of light is critical for plant growth, and blue light has a specific purpose. Gardeners use artificial light to control the quantity of UV light reaching the plants and maximize their growth. When seeds are about to sprout, blue light is reportedly utilized to boost the quantity of chlorophyll during this first stage. Indeed, without exposure to blue light, some plants cannot sprout at all.

Is prolonged usage of digital gadgets harmful to the eyes' health? 

This is also a subject of current research. Due to a shortage of conclusive evidence, many opportunities exist for hypotheses and conjecture in this area. Most scientific research that examines the possible dangers of blue light radiation from digital displays on the human visual system uses animal or in vitro cell tests. Numerous investigations also employ light levels that are not typical of everyday life or the regular use of such gadgets. None of this research has demonstrated that contemporary displays provide an increased risk to the human eye but what’s wrong with taking precautions. Check out blue-light-blocking glasses for using gadgets now! The major reason advanced too far for this result is that displays emit considerably less light than the sun. 

Cataract surgery increases your chance of being exposed to blue light.

When your eye's native lens is removed during cataract surgery, it is replaced with an intraocular lens (IOL). To maintain optimal eye health, this artificial lens should offer protection from blue light. Ensure that you and your eye surgeon discuss the type of IOL before you start. Following surgery, you may benefit from wearing blue light glasses with a built-in filter – especially if you spend a lot of time on the internet.

At what dosage does blue light begin to cause eye damage? 

Blue light's relatively high energy level affects metabolic processes in retinal cells. Thus, prolonged exposure to blue light might induce retinal damage. However, scientists can now determine which doses and light sources provide a considerable risk of causing harm. Thus far, existing scientific evidence indicates that the amount of artificial blue light that comes from conventional architectural LED lighting or screens is much below any given threshold for causing health problems in the human ocular system.

Patient complaints about decreased visual comfort and asthenopic symptoms such as headaches or burning eyes, on the other hand, are widespread and well-known to eye care specialists.

Allow blue light not to disrupt your visual comfort throughout the day or prevent you from getting a good night's sleep! Visit our website to discover more about the benefits of blue light-blocking glasses.
