Many intriguing things can be seen in Shakespeareís play "King Lear", such as vanity and folly, but along with these comes Shakespeareís displaying of sight. This he uses throughout the play, through a variety of characters; from Gloucester to King Lear, from Regan to Goneril vision plays an important part.
The irony brought on Gloucester actually resulted from his eyes. Once they were wrought out and his vision destroyed, he could finally see. Until then he hadnít realized his beloved sonís own affection and his treacherous bastardís own ambitions. His illegitimate whelp manage to destroy reason and foster suspicion until the truth was released to Gloucester, at which he then gained true sight and accompanying sorrow.
Another being affected by his vision was his majesty, King Lear. At first Learís perception was disrupted by the innocent amorous visages of his two "faithful" daughters. This image he created couldnít be deconstructed by the information (and consequently truth) of many dear friends, such as the Earl of Kent, the Fool, and the disguised Kent. All of their heeds went unwarranted until he finally confronted his two daughters about the situation. This conversation, opening his eyes, also entered another door, this one to of open insanity. From here on his vision was, yet again changed. Here, however, his sight brought forth open illusions and hallucinations he happened to describe to spectators.
Along with the others, the Duke of Albany also received a "revelation" of sight. Here he, though known to him, witnessed his on wife treachery and made a self-vow to change her misdeeds.
Finally, the sight of Regan and Goneril was affected, but unlike the others it was from foul doing done to them. Instead it resulted from a boy named Edmund, Gloucesterís bastard son. Before Edmundís "promotion" the whoreís son was a nobody, which resulted in the utter ignoring of him by the Kingís daughters, Regan and Goneril. But once he gained his position, through his devious actions, the eyes of both Regan and Goneril "opened" to him. With Gonerilís distaste in her husband and Reganís untimely widowing the two start their bickering of the boy, who, like stated above, without his position would be unknown to them and their for be of no interest.
Without Shakespeareís clever use of sight, could the story be whole? Most likely not, which could be a reason that he not only blinded Gloucester, but also heavily focused on this lack of sense.
