Bipolar neurons have synapses at both ends, forming a kind of bridge — on one end it synapses with a photoreceptor, and at the other, it synapses with a ganglionic neuron, which goes on to form the optic nerve.

双极神经元在两端都有突触，形成一种桥——在一端与感光器突触，在另一端与神经节神经元突触，神经节神经元再形成视神经。

And we think it is heavy particles or individual bursts of energy coming from radiation that are either going through the eyeball itself or going through the optic nerve.
