Plastic is one of the most common artificial materials used in our daily lives. We store food in plastic containers, carry groceries in plastic bags and drink out of plastic cups. But did you know that plastic also plays an important role in the medical industry? Plastic has caused significant changes in the medical industry by reducing the risk of infection. Before disposable plastic products existed, hospitals used to boil medical tools to sanitize them. Although this method worked, there was a danger of infection if the tools were not properly sanitized. However, disposable products have solved this problem. Another medical use of plastic is to make artificial joints. Artificial hips and knees are needed by many older people so that they can continue to walk. In the past, most artificial joints were made of metal. But plastic has the advantages of weighing less and being easily formed into any shape. Today, many joints are made from a combination of metal and plastic parts. Finally, how's your eyesight? If you wear glasses or contact lenses, you can thank plastic for giving you good eyesight. Today, actual glass isn't used to make eyeglass lenses anymore. Instead, plastic is used. Plastic eyeglass lenses are lighter, thinner, less likely to break and harder to scratch. And contact lenses are made of plastic, too. This makes them more comfortable than those that were made of glass. While plastic causes some environmental problems, it also brings us many benefits. Without it, our lives would be much more difficult. In the future, we should continue enjoy its advantages while finding ways to lessen its disadvantages.
