If you are trying to achieve a very high degree of realism, you need a very large, clear reference photograph. When you look at a realist drawing of an eye, the difference between jaw-dropping realism and a reasonable likeness is the attention to detail, This happens both in the observation as well as the drawing. They have a slight color, you will often notice visible blood vessels, and they are frequently shadowed. In a tonal drawing, there may be a highlight. A broken line is often used when drawing the lower eyelid to indicate this lightness. Take note of the highlights and reflections on the surface of the eye as these alter their appearance.Īt this angle, the inside rim of the lower eyelid is visible, and part of the upper. Observe your subject carefully to identify the patterns of their iris.
Notice that the iris is not a solid tone, but has streaks of color and is dark around the edge. To draw a realistic eye, it is important to observe it very closely. The appearance of the eye changes in the same manner. Hold it at an angle and notice how the circle changes into an oval as you turn it. To put this into perspective, look at a coffee cup or even a round bangle or ring that's handy. Because the pupil sits in the plane of the iris and is in perspective, it is an oval rather than a circle. If they are at an angle or three-quarter view and are not looking directly at you, the eyes will also be at an angle - so you are looking at them in perspective. How you draw the eye also depends on the angle of your subject's head. This detail is important because as the eye changes position in the socket, it makes the shape of the eyelid change slightly as well.
While the iris looks flat, reflections from the front of the eye show a curved surface.
The cornea bulges out in front of the iris (the colored part). You can see that the eyeball is not a perfect sphere. Watch a friend's eyes as they look from side to side. As you learn to draw eyes, it is useful to think about the anatomy of the eye.
