DisadvantageS OF
USiNG COMPUTERS
COMPUTERS HAVE A LOT OF MODELS
They are very
comfortable and useful!!
BUT THEY WILL BECOME BAD
IF WE DON`T USE IN THE RIGHT WAY !!!
Almost people who use computers don’t know how to protect their health.
Before using computers, we should know clearly about them!!!
Screen layout is not facing the window or any light source directly
Set the machine to the back of it towards the wall
Machine room is not too broad or too narrow and has enough light.
Computer tables must be large enough size
Distance from eye to screen is 60-70cm, 30-40 cm to the keyboard !!!
USE COMPUTERS
CAN MAKE YOUR EYES
BECOME BAD!
The vision is not due to poor management of radiation that is due to the screen that users always look at.

Image on the screen doesn’t look like the paper that is self-illuminated image, the contrast of low and many of the pixels.
Each continuous blinking eye doesn’t see that.
Before, people thought that the reasons cause harm is electromagnetic radiation. However, today we confirm that the radiation from the screen of the computer (X-rays, external beam flow, ultraviolet and electromagnetic ...) doesn’t exceed the value allowed and no significant damage to users
Research shows that over 10,000 people who work more easily with computers at risk of myopia or telecommunications market while myopia is now easy risk glaucoma, leading to blindness if not treated promptly.
Scientists also recommended people to check the overall eyes function to detect early signs of this dangerous disease !!!!!!!!!!!!!!!!!!!!!!!
DON`T USE COMPUTER TOO MUCH !
THANKS FOR YOUR ATTENTION !
