It's AumSum Time
-
Do smartphones make our eyes worse?
-
No.
-
They make food ordering fast and easy.
-
Ohh AumSum.
-
Listen.
-
Among all light sources.
-
A smartphone is the only one at which we stare for prolonged periods and hold it too close to eyes.
-
Hence, it puts strain on our eyes.
-
Besides this, smartphone screens predominantly emit blue light.
-
Now, our eyes are built to absorb the harmful ultraviolet rays coming from sun.
-
Thus protecting the inner sensitive membrane called retina.
-
But since they are not good at absorbing blue light emitted by smartphones.
-
It hits the retina and produces toxic substances which slowly begin to damage the retina.
-
Hence, long term exposure to blue light may affect our vision.
-
However, to resolve this issue many manufacturers have incorporated a new feature called 'Night light'.
-
Night light causes the screens to give off warmer colors.
-
Thus reducing the negative effects of blue light.
-
How are smartphones changing us?
-
Ha, no one can change the one and only AumSum.
-
Ya ya.
-
You show off.
-
Bending and staring down at our phones for several hours.
-
Increases the stress on our neck and spine, leading to neck and back pain.
-
Experts refer to this condition as text neck.
-
And it can eventually lead to serious consequences.
-
Also, at night, when we stare at our smartphones.
-
The light emitted from their screens makes our brain think that it is still daytime.
-
So, our brain does not produce the sleep hormone melatonin.
-
Causing us to stay awake for long hours.
-
And thus, disturbing our circadian rhythm which regulates our everyday bodily functions.
-
This can lead to obesity, diabetes, cancer, etc.
-
An interesting fact is that smartphone addiction.
-
Has given rise to a new phobia called Nomophobia, short for no mobile phone phobia.
-
It is basically the fear or anxiety of being without our phone.
-
Red eye effect.
-
Why do my eyes glow red in photos?
-
Because there is a devil hidden in you.
-
Oh, stop bluffing.
-
Hahaha.
-
Alright.
-
I'll explain.
-
It happens because of blood vessels in our eyes and pupil.
-
Pupil is a small opening whose size is adjusted by the circular muscle called iris.
-
In bright light, the iris contracts making the pupil smaller.
-
Thus allowing less light to enter into our eyes.
-
In dark, the iris relaxes making the pupil larger.
-
Thus allowing more light to enter and also exposing the blood vessels in our eyes.
-
Hence, when we take a photo in such a dark environment.
-
The flash of light from the camera floods into our eyes at once.
-
Some of this light gets reflected from the blood vessels onto the camera.
-
Before our iris can contract, making our eyes glow red in photos.
-
Why do your eyes turn red in the pool?
-
Ha.
-
It is because of chlorine.
-
Chlorine is not the main reason for this.
-
Chlorine is added to water of swimming pools because it is a disinfectant.
-
It helps kill germs, thus keeping water germ-free.
-
In fact, the main reason for our eyes to turn red is the presence of our bodily fluids.
-
Like urine and sweat in the pool.
-
Eww.
-
Urine and sweat contain nitrogenous compounds like urea.
-
Urea reacts with chlorine present in water, forming chloramines.
-
Now, if we regularly clean the swimming pools.
-
Then we can prevent the production of chloramines.
-
But if the pools are not cleaned, then the chloramines formed can irritate our eyes.
-
Thus making them red.
-
In addition to this, chloramines can evaporate from water.
-
Inhaling these chloramines for a long period can result in coughing, asthma.
-
And other health problems.
