What is Blue Light All You Must Need to Know about Blue Light.

What is Blue Light All You Must Need to Know about Blue Light.

Visible light is much more complex than you might think it is. What most people know is that sunlight contains both visible and non-visible light rays (UV light that can have an adverse effect on your skin). What most of us are not aware of, however, is that the visible light emitted by the sun comes in a range of rays of different colors all with varying amounts of energy. In our day to day lives, we are exposed to both visible and invisible light, all which have a range of effects on our eyesight. Whether you are stepping outside into the sun briefly, using your phone, tablet or PC or even turning on a wall switch indoors, there is exposure to light to some degree. Today’s main focus is on visible light; specifically blue Light.

What exactly is HEV Blue Light?

Without getting into complicated physics, we can define sunlight as a combination of a spectrum of colors; red, yellow, orange, green and blue rays of light, and many other shades of these lights. All these lights come in different wave lengths and energy strengths. The light rays with a relatively longer wavelength tend to have less energy, while those of a shorter wavelength have more energy. A kind of inverse relationship. On the blue end of the spectrum, the rays are of a much shorter wavelength, which would mean that they have very much energy.

Visible blue light forms part of the spectrum where the rays have very short wavelengths and the highest energy. It is sometimes referred to as violet light or blue-violet light. It is for this reason that the invisible light rays, slightly beyond the visible light spectrum, are called Ultra-Violet (UV) rays. Given their high energy levels, blue light rays are also called High Energy-Visible (HEV) Lights.

Interesting facts about HEV Blue Light

As is the case with UV lights, Blue Light has both benefits as well as dangers. Too much exposure to it has detrimental effects to our eyesight. However, on its plus side, it has a god side to it. Before we get to the benefits and dangers, below are a few facts about HEV Blue Light:

  • It is everywhere!

You read right; Blue Light is all over. The sun is the main source of Blue Light. Most of us are exposed to it by being outdoors in the daylight. However, there are so many artificial or man-made sources of this light. The most common ones include LED lighting and Fluorescent bulbs. It is notable that the display screens of such devices as; flat screen televisions, electronic notebooks, our smart phones, tablets and personal computers do emit a significant amount of blue light.

While the amount of HEV blue light produced by these devices is just a fraction of what is emitted by sunlight, the amount of time that we all spend on these gadgets is considerably a whole lot! Another factor that contributes to so much exposure is the proximity of these devices to the face, or eyes rather when using them. 

These devices have become part and parcel of our lives. We literally depend on them. The world has become an economy that operates round the clock. So whether we like it or not, we are exposed to HEV Blue Light. Someone might assume that provided they are not outdoor for long, they are good to go. This might be true, but it is the amount of time that we spend exposed to artificially-made blue light that has eye doctors worried. 

  • HEV Blue Light is Behind the Sky’s Blue Appearance!

Interestingly, the sky is not blue as many of us would tend to think. Like we mentioned earlier, Blue Light rays have the shortest wavelength in the spectrum and have the highest energy levels. As such, when they strike air, they scatter more easily and faster than all other visible light rays and also faster than any water molecules in the atmosphere. As they scatter, they do so with so much prevalence over the other light rays, which makes them domineering. Their presence is in the atmosphere is much more ‘felt’, which is what makes a cloudless sky appear blue.

Benefits of HEV Blue Light

  • Promoting good health

Every cloud has a silver lining; right? This too is the case with Blue Light. It is not all bad after all. Research shows that some exposure to HEV light has its benefits and is significant in boosting good health. It elevates moods, boosts alertness and helps in good memory and cognitive function. As a matter of fact, a condition such as Seasonal Affective Disorder (SAD- a kind of depression brought about by change in seasons), can be treated by light therapy. In the process, the light sources emit a huge bright white light beam that contains a significant amount of HEV Blue Light.

  • Regulating the circadian rhythm

The circadian rhythm is basically the body’s natural sleep cycle and wakefulness. During day time hours, exposure to blue light actually helps to maintain healthy sleep patterns. However, you need to be careful on the levels of exposure. 

The Harmfulof HEV Blue Light

  • Digital Eye Strain

Because of the nature of HEV Blue Light (short wavelength and very high energy), it scatters more than all other visible lights. Additionally, it is not easily focused. When you are using your computer, or any other device that emits blue light, the unfocused visual ‘noise/ inconsistency’ majorly reduces contrast, which can in turn contribute to digital eye strain. Digital eye strain, also called Computer Vision Syndrome, refers to some vision problems and discomfort in the eyes, caused by prolonged use of computers, tablets, smart phones or any other such like devices. According to the Vision Council’s 2015 survey, eye problems that are computer-related have significantly increased, with at least 65% of America’s adult population having signs of digital eye strain. Digital eye strain can cause eye fatigue, headaches, dry eyes, blurred visions or even insomnia.

  • Increasing the Risk of Macular Degeneration

Blue light penetrates the eye, all the way straight to the retina (the inner lining found at the back of the eye). Too much exposure to blue light can have a detrimental effect on the retina’s light-receptive cells or even damage them. This damage has effects similar to macular degeneration, which can even lead to permanent vision loss. Research is still being carried out in a bid to figure out how much blue light is too much. However, with so much exposure of this light now more than ever before, it is important to take measures to filter how much of it we consume. After all, prevention is better than cure.

  • Too much exposure can negatively affect the Circadian Rhythm

In as much as blue light has its benefits to the circadian rhythm, it has its downside too. Too much blue light exposure, especially close to bedtime, can disrupt the circadian rhythm and potentially cause sleepless nights and fatigue during the daytime. 

Why is it so Important to Shield yourself from too much HEV Blue Light Exposure?

It is obvious that our eyes are responsible for how much light we take in. They are very sensitive when compared to other body parts. When it comes to matters Blue Light, the eye is not so good with blocking it out. The human being’s cornea and lens are very effective in preventing UV rays from reaching the super light-sensitive retina. As a matter of fact, less than 1% of the sun’s UV radiation reaches your retina even when you do not have sunglasses on. This is not the case with HEV Blue Light. Virtually all of it passes the cornea and lens, straight to your retina. Knowing how adverse too much blue light exposure effects are, it goes without saying that protecting your eyes is the only way to go.

How to Protect Yourself from HEV Blue Light Exposure

We all use our electronic devices for a good number of hours during the day as well as at night. There are long term effects to this kind of lifestyle. Topping the list is eye issues on several severity levels as a result of exposure to blue light. As much as other effects are yet to be discovered, it does not take an expert to know that this constant exposure can be detrimental to eye health. Even we, the users do feel some type of way after we have been on our devices for a couple of hours. Our eyes have a way of letting us know that they have had enough. The good thing is that there are measures we can take to reduce our exposure to harmful levels of HEV Blue Light and reduce the repercussions thereafter. Below are just but a few ways of helping ourselves. You will be surprised by how much good a simple step in the right direction can help with your eye health.

  • Maximize on the ‘Comfort View’ Settings on your Device

With advanced technology, many devices come with ‘Comfort View’ settings available. What this does is changing the sharp screen light into a warmer one that has less contrast between the surrounding light and the device’s screen. This setting does not particularly shield your eyes from HEV Blue Light penetration. However, it cuts down eye strain considerably.

  • Hold your Device at a Certain Angle

HEV Blue Light is emitted straight out of the device you are using. Holding the device at a 30 degree angle or even more reduces the amount of Blue Light that gets into your eyes considerably. One may wonder how to tell if they have held their device right. It is quite simple; if you feel that your eyes are strained in any way, then you know the angle is not right. Good thing, this is something you can physically feel. Adjust the gadget you are using until you feel comfortable. This way, you will have reduced any discomfort and eye strain seeing to it that you are a step further from harmful HEV Blue Light effects.

  • Make use of a HEV Blue Light Plugin

With today’s technological advancement, there exists some software plugins that you can install in your device or browser. They actually start automatically when you start the device, altering the screen light to shield your eyes from harsh light from the screen. You can control most of these plugins by way of adjusting them to a protection level that suits your individual needs.

  • HEV Blue Light Blocking Glasses

These glasses are actually a thing that does exist. They are basically Blue Light blocking glasses that are made with some special kind of spectrum control technology that aids in absorbing blue light. They are recommended as they help in reducing eye strain, thus protecting your eyes from harm caused by continuous use of electronic gadgets. The best ones are the ones that absorb between 90-99% of blue light. They are available as from 10 dollars, so there is a pair for every budget. Regular use of Blue Light blocking glasses reduces risks of getting eye cataracts, macular degeneration and other eye-related complications.

  • HEV Blue Light Screen Filter

A screen filter is something you can mount onto your phone’s, laptop’s or tablet’s screen; it fits so easily, without tampering with the manufacturer’s screen touch sensitivity. It filters pot the blue light, allowing only minimal levels to get to the eye. Screen filters are especially ideal for children when playing computer games or going about their assignments, given that kids would be less likely to put on light blocking glasses without supervision.

Computer GlassesVs Blue Light Blockers

While computer glasses and blue light blockers both refer to eye wear whose main purpose is blocking out blue light, they have slightly distinctive features. Computer glasses were initially designed to suit people who are always on their computers for several hours straight, for instance gamers. They feature yellow-tinted lenses which filter out HEV Blue Light. Comport glasses are really great for protecting your eyes, however they are not that ideal for every day wear as the yellow tint distorts colors.

Digital devices have become so prevalent in our lives and exposure to blue light is no longer restricted to your computer only’; it goes far beyond to our laptops, electric notepads, smartphones and a myriad of other devices. With this new development, computer glasses are becoming more and more phased out. Technological advancement has seen the invention of blue light blocker lenses. These are basically clear lenses that block HEV Blue Light penetration and also provide maximum UV protection with minimal to nil color distortion. These blocker lenses are infused with a HEV Blue Light blocking polymer which absorbs HEV Blue light preventing it from getting through the lens and penetrating your eyes. Given its clear lens, it is quite ideal for everyday eye wear preventing you from daytime Blue Light penetration. 

The Importance of HEV Blue Blocker Computer Glasses
