The computer is a very popular technological invention. It was invented in the mid-twentieth century. It has very quickly ascended to the top of people’s list as to what they need to survive the day. The computer is a very famous and [sometimes, usually] helpful invention to all. It is used by millions of people around the world, for different purposes. There are some positive points to its uses, but also some negative points. In this essay, I will talk about the negative points. The three negative points of using a computer are: it may harm your eyes, it can take time away when you can be doing more beneficial things, and too much information written on it about yourself can be dangerous.
Long hours at a computer can harm your eyes, say experts. They advise frequent short breaks every half hour or so to minimize the damage. Studies have shown that eyestrain and other vision problems can be found in as much as nine out of ten people using computers often, say Kerry Beebe, an optometrist and spokesman for the American Optometric Association. The most common symptoms are eyestrain, blurred vision, double vision, excessive tears, dry eyes and excessive blinking or squinting. Visual problems can also result in physical problems such as headaches and neck or shoulder pain, reported Health Central. So this means you must never use a computer non-stop without taking any breaks – you should always take breaks to reduce the risk of any of these eye and body problems.
The computer may waste a lot of time for you – you are capable of using your time way more wisely. It wastes time because there are many things on it that distract you when you’re trying to do something, like pop-up ads. You’re trying to get somewhere, and then one of them comes up and maybe tempts you to click on it. This is an example of wasting your time on the computer. Little things like this can make you even lazier to finish the work that you actually had to do, so you don’t really get across completing it. Then again, you choose if you want these things to affect you. If you actually wanted to finish what you had to do, you wouldn’t have let these things influence you.
The last negative thing about computers is that if you put out too much information about yourself, it might be very dangerous. There are many people who say they’re somebody that they’re not, and anybody that is not too careful can easily be tricked into believing them. Internet stalkers have killed at least four teenagers in the past three years, and law enforcement authorities count about 5,000 reports of attempted sexual predation over the Internet in the past year, according to Parry Aftab, who is the executive director of “Wiredsafety.org,” which is an Internet safety organization. According to this information, you could easily become one of those victims. This is why you must take caution when using the computer.
All in all, a computer has many negative points and effects; these are only some of them. A computer can harm your eyes if you’re not careful in how you’re using it. If you use a computer, you should use it responsibly. You should understand that you must use your time wisely on it too. Time is something that cannot be brought back, so you must use every minute of it so that it’s worth it in the long run. Lastly, you have to be careful when posting information about yourself. You should post too much, because somebody might want to make you a victim in attacks like the ones mentioned. Also, it is better to not post any personal pictures up. In conclusion, a computer can be very negative if you do not use it correctly. You need to be aware that everything you do affects you.
