About myself 1

I chose this topic because my eyes are bad

I use my computer VERY often and wanted to know if it was the cause of my low eyesight

When I was 11 years old, I got my first laptop

I used it everyday, every night

At that time, I still had very good eyesight

About myself 2

Later on, I bought myself my first iPod

I also used it everyday and night

As time passed, I noticed that my vision was not as great as a few years ago

In fact, my eyes were so bad (0.2 on both) that I had to get glasses

I went to an eye doctor several times

About myself 3

After I got my glasses, I started blaming myself for the overuse of computers and iPods.

But in reality, I found out that it was not the computer that reduced my eyesight, but was just the genes

Both my father and my mother have very bad eyesight

My father is near sighted and my mother is far sighted

Myth about computers 1Computers DO NOT damage or reduce eyesight

People misunderstand with “eyestrain”

The effects of eye strains are not equivalent to eye damage

It WAS true in the old days with PEMR (I’ll get there later) but not true now-a-days technology

Myth about computers 2

Eyestrain - fatigue of the eyes

The reason that we get dry eyes is because we tend to blink fewer when the eyes are concentrated on one object (in this case the computer screen)

The reason our eyes become blurry is because when we rest our eyes, we have to focus somewhere else

And when that happens, the ciliary muscles tighten and soften rapidly

That is why the vision blurs out.

Myth about computers 3

Think about it this way

Looking at a light bulb in the dark will make your eyes dizzy

Same with computers, it is like a light bulb

Computers are visible because the pixels in them are just illuminated

Hence computers itself does not damage or reduce eyesight

PEMR 1

Pulsed electromagnetic radiation

Generated only from CRT based computers

The electrons which flow on the screen of the CRT based computer create the radiation

The radiation, when at close range, disturbs the balance of all living cells, including the cells in the eyes

PEMR 2

However, now-a-days computers no longer are based on CRT, but rather on LED and LCD

Hence the computers did not affect or reduce my eye sight (in this generation)

CRT displays were used in the 19170-80, so it is not linked to me

We can say the computers do damage eyes, but that is only in the old days and now it is false information

Method/cure to eyestrains 1

Though computers do not harm the eyes, it does indeed give you eye strains

The best method to prevent ANY eye strain is to use the 20-20-20 methodEvery 20 minutes, look away at an object 20 feet

away, for 20 secondsBy doing this, the eyes will not get too used to the

computer monitor, hence no blur or dry itchiness

Method/cure to eyestrains 2

If your eyes are feeling itchy, it is because you are concentrating too much

Relax

Have a drink of water

Look at green things, because the eyes tend to relax better

If it itches very badly, use an eye drop to liquify the eyes.
