time. So a new kind of glasses is more and more popular now. And millions of people like it very much. It
is contact lenses (隐形眼镜).
Millions of people use the contact lenses. For anyone who doesn't mind sticking his fingers in his eyes,
there are clear advantages: contacts correct vision better than glasses, less often crushed underfoot, don't
make you look boring, and come in a huge variety of forms-safe, firm, colored, and even theatrical.
