A lens bends the path light takes (this is called
refraction), so that a photon that would otherwise miss your camera gets directed into it. Again with a rain analogy: A raindrop that falls a meter away from you misses you, but if you could deflect (refract!) the path of that drop a little bit while it s still up high, it ll be aimed right at you, and you get wet.
In the case of the Terrascope, the lens is actually Earth s atmosphere. When light moves from one medium to another (like air to water, or space to air), its path bends a little bit. The amount it bends depends on the angle it enters and the stuff (what we usually call the ....
