Blue light blocking glasses has its own purpose. They also offer a lot of benefits – but do blue light/computer glasses work on someone who’s color blind?
If you see no colors, does blue light affects your eyes?
Most people think that it doesn’t affect you since you don’t see it. But that’s just not true.
In this post, you will find out why and what is the correct answer. But not only that.
If you’re new to computer glasses and you’re looking to learn more in order to find your first ideal pair – this is the right place to be.
How Does Color Blindness Works?
Did you know that color blindness 1 out of 12 men and in 1 out of 200 women in the world?
Unfortunately, color blindness occurs directly in the retina where light-sensitive cells fail to respond to variations of wavelengths.
Exactly this variation of wavelengths allows people to see colors.
There are 3 different types of color blindness:
- Total color blindness
Therefore, not all color blind people are not able to see all colors. Some are able to see a couple of them and are able to perceive some colors differently.
The bad news is that there’s no known cure yet to treat color blindness. On the bright side – color blindness doesn’t affect vision.
And since you know that blue light blocking glasses block blue light – are these glasses ideal for people who are color blind or they’re pretty much useless?
That’s exactly what you’ll find out down below – so keep on reading as we first teach you how computer glasses work.
How Computer Glasses Block Out Blue Light?
Specially designed lenses are able to block out blue light out of the all-color spectrum.
However, these glasses don’t block out blue light completely. They block about 70% which is more than enough to provide the necessary benefits.
This is one of the reasons why you won’t even notice the difference between a regular lens and a blue-light blocking lens.
Lenses of computer glasses have a filter that can absorb blue light which means that not all blue light passes through.
Have you ever seen a trick done by blue light to test out the absorption of blue light by the lens? You can see it in the image below.
This is one of the ways to know that the blue glasses actually block blue light. But why exactly blue light?
Benefits of Blue Light Blocking Glasses
Scientists found out that from all colors in the spectrum – blue light is often the most harmful one for our eyes. Why?
Blue light is not totally harmful. Our body needs blue light and we get it from natural sources.
However, all screens emit blue color along with all other colors from the color spectrum.
We all use computers, phones, and we watch TV for long hours. This leaves us being overly exposed to artificial blue light which isn’t good for our eyes.
Some of the symptoms you can experience due to overexposure to blue light:
- Dry eyes
- Watery eyes
- Blurry vision
- Inability to focus
- Disruption of sleep pattern
And how wearing blue light glasses can help you?
These are the benefits you can expect to notice after only a couple of hours of wearing computer glasses:
- Minimum glare
- Better eyes focus
- Reduced previously mentioned symptoms
- Healthy body clock
But how exactly does blue light affect our body clock?
Prolonged exposure to blue light can delay the release of sleep hormone known as melatonin. Therefore, you might not feel sleepy at all even if you were doing physical activities the whole day.
So Should You Use Computer Glasses if You are Color Blind?
Needless to say, blue light blocking glasses offer a lot of benefits. We believe that every person would benefit from computer glasses, especially considering the modern world we live in.
It’s hard to stay away from the TV, our smartphones, and laptops/computers, especially if you use them for work.
But should you get a pair of blue light blocking glasses if you are color blind?
The answer is yes and no. It depends.
But on what?
It depends on the type of color blindness you have. We’ve mentioned it earlier, and you probably know it by now – there are 3 types of color blindness.
Not all color blind people perceive colors in the same way.
Some color blind people can see only red, green, or blue among all other colors from the color spectrum. There are also rare cases where people can not see any colors at all.
Therefore, if you are able to see blue light, you will be affected by it and you will experience the same symptoms everyone else experiences. This means that blue light blocking glasses would help you limit the amount of blue light you see so you aren’t overly exposed to it.
It might seem ironic to try and block out one of the colors you are able to see among others you can’t see – but you will still see about 30% of the color. Also, you will only wear computer glasses when you’re staring at the screens.
Therefore, you will experience the benefits of computer glasses.
But what if you can’t see blue light?
It’s very rare to be color blind to blue light – but it’s possible. If that’s your case, blue light blocking glasses won’t benefit you in any way since your eyes already aren’t able to perceive the blue color.
You have to consider different types of color blindness to understand whether blue light blocking glasses would help you or not.
It can sound ironic to use blue light blocking glasses to block out one of the colors your eyes can still perceive – but it’s for your own good.
On the bright side, color blindness doesn’t affect the vision – so you still should consider protecting your vision.
If you don’t – you will experience the same symptoms everyone else does. And if you’re wondering how come you can’t fall asleep at night – the answer might be simple
Overexposure to artificial blue light.
