The development of business and entertainment has led to increasing numbers of problems for our eyes. Eye strain caused by the excessive watching of TV, computer monitors, books, and other devices has become a severe problem. This is a concern among children who are becoming more and more addicted to video and computer games. They spend long hours staring at the screen with few breaks. Other things can also cause poor eyesight. Pollution can damage the eyes, as well as a poor diet. This is especially true for the poor in society as they may not be able to afford the food necessary to provide everything that their bodies need. There is also an increase of people born with bad eyesight others develop poor vision at an early age. This can be caused by the misuse of a person’s eyesight. This misuse can come in the form of being consumed with schoolwork and study until their vision begins to blur. They may not take care of their eyes with such things as eye drops. Many may not even get glasses. It is natural that a person with poor eyesight should wear glasses or contact lens. However, many people decline to use these since they feel that it may take away their good looks. This is really surprising as a person’s eyes are very precious. If they are lost, it could seriously damage the livelihood or standard of living of that person.

商业和娱乐的发展给我们的眼睛带来越来越多的问题。过度地看电视、电脑显示器、书和其他设备引起的眼睛疲劳已经成为严峻的问题。这关乎那些越来越痴迷于录影带和电脑游戏的孩子。他们长时间地注视屏幕，几乎不休息。其他因素也会导致视力下降。污染会伤害眼睛，糟糕的饮食也是原因之一。由于买不起可以提供身体所需的所有营养的食物，这个问题对于社会中的贫困阶层来说更为突出。天生视力较弱或幼年视力发育不佳的人不断增多。这可能是由用眼不当所引起的。这种用眼不当可能以应对过多作业和学习的形式出现，直至视力开始变得模糊不清。他们可能不会用眼药水之类的东西来照顾自己的眼睛。许多人甚至不戴眼镜。近视的人配戴眼镜或是隐形眼镜是很自然的事情。但是很多人拒绝佩戴，因为他们觉得戴眼镜会影响外表的美观。这确实让人惊讶，因为人的眼睛是那么宝贵。如果失去视力，这将会严重影响人们的生计或生活水平。
