I packed your sunglasses with the green lenses.

In your eye, the lens is the part behind the pupil that focuses light and helps you to see clearly.
1. a transparent optical device used to converge or diverge transmitted light and to form images
2. (metaphor) a channel through which something can be seen or understood;
3. biconvex transparent body situated behind the iris in the eye; it focuses light waves on the retina
4. electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons
It's kind of like the way a lens magnifies a beam of light.
它是一种象一种能放大一束光的方法.

在二者的镜头群之间在客观上没有全面的不同.
