Drawing the Human Head Series: Lesson 9 — DETAILED STUDY OF THE PARTS OF THE FACE (CONTINUED)
Let’s move on to the visible forms of the eyeball — to that small circle formed by the iris and the pupil — and let’s summarize the characteristics of shape and tone that one must generally take into account when drawing this element. Here they are. (Study these texts and their corresponding illustrations as if you were going to draw this important part of the eye. And think about it every time you draw it.)
It remains to mention this small pink ball that belongs to the lacrimal system and is located on the inner side of the eye. Remember its size, its place, and its color by looking carefully at the illustrations in which it is most visible.
THE DOUBLE SYSTEM
And here are the two eyes, both moving at the same time, both placed on a curved surface, both having a spherical shape… that is to say, possessing all the possible problems of vision but in double (fig. 61).
The fact that they are both located on a curved surface means that we can never see them as two identical repeated forms; except, of course, when they are viewed absolutely from the front. If that is not the case — if, for example, they are seen in three-quarter view — one of the two eyes will be almost in profile, while the other will be more frontal.
The real problem is this one; the only solution, when one has to draw, is to look carefully at what the model “says” — what these eyes really look like, those of the model — or to imagine them as the two small balls we have spoken about.
If on the other hand you think that these two balls always turn at the same time and that in the end they are two identical bodies seen from a different angle, it will be impossible for you to draw eyes that cross — which is the most common defect among amateurs —. It is a simple question of perspective, where the position of one eye must determine that of the other (fig. 62-63).
