In the story of the man who leaves the cave, it is mentioned that if he returns to the cave after seeing the sun that he will be ridiculed because his eyesight has been ruined.
In the Oxford English Dictionary, eyesight is "The power or faculty of seeing; sight: attributed also to the heart, soul, etc". Looking at the way that Plato utilizes the word eyesight can be seen as not just referring to his actual eyes but to their soul and heart because they have been exposed to truth and they will no longer be able to be satisfied with the life of the cave.
When we think of eyesight we should think of more than just the actual eyes which were changed by the light but of the enlightenment which reached the soul.
