Aside from the correlations between sight and touch, a key theme in Berkeley's An Essay Towards a New Theory of Vision

As a philosopher Berkeley is known primarily for his An Essay toward a New Theory of Vision
(1707), for his Principles of Human Knowledge (1710), and for Three Dialogues between Hylas and Philonous (1713).

It must be emphasised that Ptolemy's theory of vision
had prevailed until that time -- that one could see because the eyes themselves emitted rays of light.
Thus even Aristotle's passive and anti-materialist theory of vision
can retain an active role for the eye in causing physical changes in the world (albeit not as an aspect of its activity of seeing).
The commentaries offer evidence of a strategy used in late antiquity to insulate work on optics from the dominant theory of vision
, in effect asserting the independence of the mathematical models of the intermediate sciences from conflicts with doctrines in natural philosophy.
The Western reception of the Book of Optics, initially known in Europe by the Latin title Perspectiva, catalyzed the emergence of a pictorial theory that, as Belting puts it, "made the human gaze the pivotal point of all perception and enabled artists to reproduce this gaze in paintings." Belting attributes this watershed misreading to a transformation that occurred when Alhazen was translated--changes in vocabulary suggested to readers of Latin that the theory of vision
must also entail a study of pictures.
"Many of our visitors will be surprised to learn that from these ancient desert cities came the theory of vision
, techniques of quantitative chemistry and trigonometry and the numeral systems that we use today," he remarked.
Why we see what we do redux; a wholly empirical theory of vision
But Bradatan shows that there are many more Platonic themes in Berkeley's philosophy, that several are present in his first writings, and that--from the New Theory of Vision
to Siris--they form a coherent network.
In particular, his belief, supported by empirical evidence, that vision was the reception of light rather than its transmission forced him to assign to psychology a new and central role in his theory of vision
. Two other chapters focus on Islamic developments on Greek mathematics.
At a time when the Aristotelian theory of vision
had gained wide acceptance, Cavalcanti continued to exploit the range of available optical theories, as did Dante, for poetic purposes.
