The Eyes

• Eyes begin to appear as two lumps on face on day 10.

• Optic vesicles stretch out and form on day 11.

• The purpose of the optic vesicle is to make way for full eye development.

• Walls of the Optic Vesicles thicken on day 11.

• Optic Vesicles create an inner thinner layer on day 12.

• Optic Vesicles create a thinner outer layer that will eventually be the pigmented layer of the retina on day 12.

• The purpose of the pigmented layer is to help the eye see color.

• Pigment granules appear on the surface on day 13.

• Also, the surface ectoderm will create the lens of the eye.

• Towards the end of the process the blood vessels will connect and form around the eye.
