A new contact lens (隐形眼镜片) has been developed by scientists from America, Britain and China. It can check for illnesses at any time by examining chemical in tears. A new sensor (感应器) is used to achieve the purpose.
Scientists hope that the improvement could help to deal with sudden medical event. Dr Zhao Yunlong said. "COVID19 has had a great influence on the scientific world. And we are doing research to help people deal with similar events in the future. "
When introducing the new contact lens, Dr. Guo Shiqi, a researcher at Harvard, said. "In the past, the sensor was put between the layers (层) of the lens. It didn't have direct contact接触) with tears. But our new sensor is smaller and smarter, It can be fixed to a lens and keep direct contact with tears. What's more, it causes no discomfort to the eye. "
The contact lens has not been put to the market, but researchers are quite sure that it will be welcomed. It is especially useful for the old and those who may experience sudden medical events.
As society develops, scientists are supposed to develop more products that provide care and convenience (便利) for people. The contact lens is one of what they are researching on. Earlier, California company developed another kind of contact lens using LED technology. It can show the health information on the mobile phone. Steve Sinclair, head of the company, said, "We have to build something that helps you when you need it and stays off when you don't need it."
