  1. Do computers damage the eyes or reduce eyesight? Yuko Ohmori

  2. Table of content • About myself • Myth about computers • PEMR • Method/cure to eyestrains

  3. 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

  4. 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

  5. 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

  6. Myth about computers 1 • Computers 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

  7. 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.

  8. 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

  9. PEMR 1 • Pulsed electromagnetic radiation • Generated only from CRT based computers • The electrons which flow on the screen of the CRT based computer createthe radiation • The radiation, when at close range, disturbs the balance of all livingcells, including the cells in the eyes

  10. 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

  11. 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 method • Every 20 minutes, look away at an object 20 feet away, for 20 seconds • By doing this, the eyes will not get too used to the computer monitor, hence no blur or dry itchiness

  12. 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.
