Since the speed of light is about a million times as great as that of sound waves, the reflection of light waves may very well be applied in detecting a target and its distance.

光速大约为声速的100万倍，因此光波的反射现象可以有效地用来探测目标物及其距离。

It's sweet and simple: the camera captures the reflection of light on the user's eye, and image processing technology then calculates the user's viewing angle to allow for hands-free navigation on-screen.

The result is that the reflection of external light is dramatically suppressed.
