Probably he does have clear lenses. All goldfish have a full covering of scales, but in some (calico varieties, shubunkins), the pigment layers are missing from the scales, making them transparent and invisible. The gill plates are also transparent. A few scales may be pigmented, giving the impression of a random scattering of scales.

It looks quite uniform, probably it is throughout the lens tissue. It may have a protective function, like sunglasses, because the pupil does not contract in bright light. Strangely, my darkest coloured fish, which is jet-black with brown lenses, hates bright light, while the white ones don't mind it.
I don't know if the colour difference makes them behave differently. Maybe when a goldfish complains that 'no-one can see my point of view', he really means it!
I never knew what quantum physics was until now, the Dr. Quantum video was the first time that I have even started to understand it.
