Millions of people use contact lenses (隐型眼镜). For anyone who doesn't mind sticking his fingere in his eyes,there are clear advantages: contacts correct vision better than glasses, are less often crushed underfoot, don't make yolook boring, and come in a huge variety of forms——soft, firm, colored,and even theatrical.
More and more people are turning to use of contact lenses. But are they safe?
Latest research from Austria shows that not all chemicals are effective in killing all germs(细菌)——and some of these germs can cause blindness in just 24 hours.
While most problems with contacts still can go back to poor hygiene (卫生) or overuse, not all sight-threatening conditions only happen to those who wash their lenses under the tap or decide, while tired and emotional, to sleep in their lenses for the third night running.
Two of the biggest eye-damaging killers——protozoan acanthamoeba and bacteria pseudomonas——as all around us, in our homes and water supplies. This seemingly harmless pair can cause blindness through keratitis(disease of the cornea) .
"The cornea (角膜) is like a five-layered sandwich," says Raymond Curran, a doctor from Omagh, Northern Ireland."Once the bacteria get into a layer they can reproduce there and turn the cornea opaque(too dark to see through) ."
An optician(验光师)may see one possibly sight-threatening case each month, but at an eye hospital there may be several each week. Acanthamoeba, often seemingly mild,can be misjudged until it is too late. Meanwhile, pseudomonas, more seriously, can cause increasing sight loss with each hour that passes. If not treated immediately, patients may need a corneal replacement.
And the really bad news, according to Professor Roger Buckley,at the Moorfields eye hospital in London, is that acanthamoeba is"one of the hardest germs on Earth"——it can survive in Antarctica.

There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy, the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.
People who are to be happy fix their attention on the convenience of things. The pleasant parts of conversation, the well prepared dishes, the goodness of the wine, the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore,they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend(hurt)many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention ofcriticizing(批评)and being disliked is perhaps taken up by imitation (模仿) . It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.
Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoidany contact (接触) with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.
