Hello guys in this time round I will be looking at the blue light which is also known as HIGH ENERGY VISIBLE LIGHT,which is  related to my research.

Blue light is a colour in the visible light spectrum that a human eye can see. Blue light is a short wavelength, which means it can produce a high amount of energy.

Blue light can impact somebody in which according to research it can cause eyestrain, fatigue, headaches, and sleeplessness.

It's wavelengths are everywhere in the world and it surround us(natural blue light). In fact, they’ are the reason as to why the sky appears blue. These short blue wavelengths collide with air molecules, which causes the blue light  to move in continuous random motion or disperse and makes us process the sky as blue.

They’re also a natural form that helps to:

(1)regulate the body’s sleep and wake cycles, also known as your circadian rhythm.

(2)Blue light also helps to boost your alertness,

(3)elevate your moods,

(4)heighten your reaction times and increase your overall feeling of wellbeing.                                                                                                                                          Artificial blue light sources include electronic devices,TVs, Smartphones, computers, laptops, tablets and gaming systems), electronic devices, LED and fluorescent lighting.

In the next time round research I will be looking at both positive and negative impacts of the blue light .

Hey Dorcas!

Great post! I feel like blue light is something we are becoming more aware of recently as the effects of electronics on our bodies are more prominent than ever. So, I think it's great that you decided to do some research about this. I think the most common thing we hear about blue light is its ability to severely disrupt our sleep; so, if you want to do some more research about this, I think that would be interesting. 

Here are some potential sources for your next round about the negative effects of blue light:


Great job and good luck!

Hey Dorcas!

I thought your round was nice and easy to read but very informative at the same time, so great job with that!  I find it so interesting that blue light is the only thing humans can see, considering that are eyes are so complex already.  Your going in a really interesting direction with talking about artificial blue light in technology.  I've always found it really cool and eye opening to learn about all the effects it has on humans and how we still continue to use it more and more without trying to prevent any of the negative impacts.  


^here is a site aout the affects on vision


^ this site is talking about the positive affects of blue light, which isn't as common to hear about.  

Good luck with your next round!

Hi Dorcas!

Great choice of topic! I clicked on your post very fast because I have watched a couple documentaries about blue light. It is very interesting that we are all suddenly aware of this light; because it can be transmitted through technology, such as cellphones or laptops. It is commonly known to have negative effects on your eyes, so I believe it would be very interesting to elaborate on it's effects on the eyes on your next post! 

Here is a source that might help you learn about the negative effects of blue light to the eyes: 


Good job !

Hey Akinyi

Its exciting to look up at critical things happening around our lives with technological advancement embedding in our lives so evidently, often that goes ignored. Am glad youre finding more about this. In fact, your inquiry question poses a huge question to  humanity and calls us to realize how best we can understand solar radiation and prevent current and future dangers of solar radiation which obviously integrates environmental concern. Imagine a world without computers, without tablets, without cell phones. Apparently it would be so difficult to shun the use of electronic gadgets which, as I found out have been made in such a way that they induce their own high energy light. It is therefore, pretty informing to be aware of the dangers of blue light.Among other effects, I found out that blue light can cause fatigue to the eyes, especially when the light is beyond the wavelength the retina of the eye can focus.
