夜晚人们外出时,都要带上手电筒,很不方便。我想设计一种夜光眼镜,镜片用纳米材料制成,镜片很薄,戴上眼镜就可以看到周围的事物,感觉像白天一样,而 When people go out at night, they must bring a flashlight, which is inconvenient. I want to design a kind of luminous spectacles. The lenses are made of nano-materials. The lenses are very thin. You can see the things around you by wearing glasses and feel like the daytime.
