Nowadays life becomes techno friendly, lots of people even little children use computers for many hours a day. Parents were concern about the effects this modern technology may bring to their children as well as to the users.
How does computer affects your EYES?
Research has shown that nine out of ten people using computers are suffering from CVS (Computer Vision Syndrome). The vision problems involved in CVS include blurred vision, itching, burning, dry eyes, teary eyes, difficulties in focusing, double vision, squinting, eye strain, headaches and often pain in the neck, shoulders and back.

Studies have shown that eye strain is a common complaint among office workers, students and home business entrepreneurs adjusting to extended time chained to a computer screen. In order to accomplish all the daily tasks necessary during their work schedule, eyestrain is now surpassing carpal tunnel syndrome as the number one complaint, and has now been given the name of Computer Vision Syndrome.
A computer is probably one of the most dangerous thing you can give to you if you want to kill your eyes. There is something called eyes tension that will become worse and worse if you keep using your computer for very long periods of time without resting. Your eyes need to rest at least 15 minutes for every hour of work. If you do not rest them you risk losing them too soon.
How does computer games can affect your children's brain?
Well, many parents worry about the mind bending influence computer games might have on their children. But one researcher in the United Kingdom has been investigating a much more tangible side effect: computer games can occasionally induce epileptic fits.
It's a form of a condition called Photosensitive Epilepsy. Professor Graham Harding and his colleagues at the University of Aston in Birmingham have studied a group of such children and adolescents who had convulsions while playing at the computer.
Photosensitive epilepsy is best defined as a tendency to recurrent convulsions, precipitated either by flashing lights or patterns.
Photosensitivity is a strange condition. You have to have a hyper-excitable visual cortex, and a low convulsive threshold. That means that if you or I were presented with a flashing light in a discotheque or something, our brain automatically damps that down. In these patients, it doesn't. And so if that flicker goes on and it's at the right flash rate, then they will be precipitated into a convulsion.Photosensitive epilepsy is best defined as a tendency to recurrent convulsions, precipitated either by flashing lights or patterns.
How common is it? It's relatively rare in the population. It occurs at one in three and a half thousand. It's more common in girls than boys, about sixty to forty - which is different from epilepsy, which is slightly more males than females. But the interesting thing about it is that it most commonly occurs around puberty.
And so most photosensitives are between seven and 19 years of age when they have their first attack. One in four patients lose photosensitivity. But the other three out of the four will continue for the rest of their lives, even up to 70, 80 years of age. One in ten. And why is particularly more common at that age?
Photosensitive epilepsy which is really a product of the modern computer age.
But today, there is nothing to worry about, as the time went on, modern inventions of computer devices that are being used to lessen or to prevent those bad effects that computer may create to our health. After all, it is still the user who knows how to manage himself in order to get rid from those harmful effects.
