“The application of scientific knowledge for practical purposes, especially in industry:advances in computer technology.”(Hawker,1995,P.719) Technology is fundamentally changing the way mankind lives. It makes the communication with people easier and faster. And people's lives become more abundant than before. Technology has given people more entertainment, such as TV, computer games, Internet, and so on. Technology also has changed the way of people’s work more convenient than before. But all these have potentially adverse effects on our health.
Although the computer to work and play in people's lives brings convenience but it also had some health problems. Sitting at the computer too long cause many people got sick. Not conducive to people's health. “If you spend all day staring at a computer screen, you may be at risk for computer vision syndrome (CVS), also called occupational asthenopia.”(Blend, 2013, n.p) CVS encompasses all eye or vision-related problems suffered by people who spend a lot of time on computers. CVS will make your eyes dry, tearing, red, burning eyes, eye irritation, or headaches, and even pain in the neck or back. I think this is a nightmare for your eyes. “Research presented by the American Optometric Association indicates that ‘more than seventy per cent of users that work on a computer monitor (which is over 140 million) experience computer vision syndrome (CVS) or eye fatigue.” (Kohli, 2013, n.p) Computers emit radiation wave are often ignored, but is also a big problem for people’s body. Without doubt, the biggest hazards for people’ body of computer is the radiation. Excessive radiation harmful to human reproductive system, may directly affect the minor's body tissues and bones, causing vision, memory loss and decreased liver hematopoietic function, can lead to serious retinal detachment. Computer radiation will directly affect the endocrine system of stable chaos. Cause skin metabolism is not the law. Coupled with a computer magnetic, will accumulate some dust and dirty air, and these will affect the quality of your skin. It is very horrific for us.
Earbud are used with many digital music players. We always use it when we are free. “They fit inside the ear but don't cancel out background noise, requiring users to turn up the volume, often to 110 to 120 decibels -- loud enough to cause hearing loss after only an hour and 15 minutes.”(Hill, 2013, n.p) The maximum volume created by gadgets such as MP3 players and blue tooth headsets are equivalent to a jet plane taking off nearby. This destroys the sensory cells that take auditory information to the brain. And today, people spend much more time listening to their portable players, exposing themselves to damaging noise for longer periods of time. As a result, young people are developing the type of hearing loss normally seen in much older adults. “Nearly 70 per cent of 18- to 24-year-olds and 72 per cent of 25- to 34-year-olds suffer from tinnitus, or ringing in their ears, an Australian Hearing report has found.”(Doherty, n.d, n.p) That means there will be about 70% of people will become deaf in the future. I think it is a big problem with our health.
Then I will give you some solution for this problems that using computer. “You can keep your monitor about one meter away from you to avoid CVS, and be sure it is directly in front of you to reduce eye movement. Adjust lighting to remove any glare or reflections.” (Blend, 2013, n.p) You can also adjust the luminance of your monitor to anesis eyestrain. I give you some simple steps to help you, like looking away from your monitor every 20 or 30 minutes and focusing on some green plants far away. I also have some solutions to against the computer radiation. When you use a computer, it is best before the monitor with better quality of radiation.
