I had a physician in my vicinity (i.e. my own conscience). But I did not consult him in connection with my deeds. The result is that my eyes, which formerly could distinguish between right and wrong, ultimately suffered from cataract (and they could no more do the above job).

I shunned them when physicians were my neighbours,
For I had in my eyes cataracts rare.

Physicians were in my neighborhood, but I did consult them,
That is way I have cataract in my eyes.
