Now we’re going to talk about the actual eye itself. Since this is a sculpting forum, I won’t be getting into the actual consctuction of the eyeball and the way it’s affected by light. There are tons of resources on that do a great job of that. Alex Alvarez from Gnomon has a great eye tutorial that covers this really well. http://www.thegnomonworkshop.com/tutorials.html
1. Eyeball- the eyeball is roughly about an inch in diameter and lines up pretty evenly with the opening of the eyelids. The eye grows most in the first month of life and then gradually slows down until puberty. After puberty, the eyeball stays about that size for the rest of one’s life. There is a cushion of fat around the eyeball for protection. That is why the eyes seem to sink in when someone has extremely low body fat.
1a. Sclera- The whites of the eye
1b. Cornea- the cornea is raised and projects from the eyeball like a little dome. It affects the shape of the eyelids. And the shape can be seen moving when the eye moves and it is especially pronounced when the eye is closed. Many artists don’t take the cornea into consideration when they are sculpting the eye. The angle of the orbital cavity is slightly down and slightly facing out. This is to allow humans to see down and to aid periferal vision to the side.
1c. Iris- The flat disc behind the cornea
1d. Pupil- the black hole.
2. Orbital cavity- The eys stick out just a little over the mouth of the orbital cavity. The orbital cavity starts out roundish and gets squarer as you grow older. it’s rounder in a woman than in a man and rounder in asian people then in white. And rounder in white than in Black peopls, generally speaking.
3. Eyelids- It’s important to remember that the eyelids have thickness to them and that they pretty much take the shape of the eyeball and the cornea. The upper eye lid is thicker than the lower, sometimes twice as thick. They are similar on the inside.The edges of the eyelids are flat except for about one-sixth of them on the inside corner. See picture. Usually, but not always the inside corner (called the medial canthus), is lower than the lateral canthus (outside corner). This is so that the tears can drain into the tear ducts.
4. Caruncle- it’s a small nodule in the medial chanthus (inside corner)
5. Plica semilunaris - this is a half moon shaped piece of membrane. Prehistorically, it was a third eyelid that closed sideways for protection. (that’s for you animorphers :)
6. Eyelashes- They usually come out in rows of 2 and 3. (Please let me know if you need me to clarify this)
7. Fold Follows the line of the top rim of the orbital cavity.
