The Secondary Light is likewise of three sorts, the Direct, Reflected and Refracted. [...] The Refracted Light is that (which the Philosophers say) is ingendred by the Direct Light, as it fals on Christals, Armour, Water and such shining Things as are apt to Ingender the same : and is nothing but the breaking of the Direct Light upon these Bodys, which it causeth round about in every place, as may be seen in clear water towards the bottom, as likewise on the Superficies next the Eye.
