In plain words
Unlike physical eyes that can be blinded, the seer's vision is never lost. As scripture declares, the seer's awareness suffers no break; therefore, the seer remains forever the experiencer.
Close to the Sanskrit
The vision of the seer is not lost, just as eyes and others, but for the seer it is not lost, thus indeed it has been said; therefore the seer is always an enjoyer indeed.
