How to draw human eye section

Human eye is spherical organ. The front portion is protruding out and it encloses lens, iris. It has three layers namely outer sclera, middle choroid and inner retina. Retina is sensory layer of eye which has millions of  Photo receptors called and Rods and Cones. An optic nerve emerges from lower side of  eye ball.Lens is transparent and is held in position by suspensory ligaments. Entry of light in to eye ball is controlled by Iris which is made up of pigmented smooth muscle.

.Chorioid layer forms transparent cornea before lens.Lets draw the eye ball from a circle. You can make a circle using rounder.

 Step 1:

Draw a  circle and a line through center of circle as shown.

Mark two lines on either sides.

 Step 2:

Erase the portion of  curve.between the two lines.

 Step 3:

Draw an imaginary arch before the eye ball.

Step 4:

Connect the arch on either sides as shown.

 Stop 5:

Clean the extra lines.

 Step 6:

Make a double line along the out line.

 Step 7:

Put a dot to position the lens correctly as shown.

 Step 8:

Draw ciliary muscle on either sides as shown.

 Step 9:

Draw iris as shown.

 Step 10:

Draw suspensory ligaments connecting lens.

 Step 11:

Draw conjunctiva on cornea as shown.

 Step 12:

Draw retina on inner side of the choroid layer.

Step 13:

Erase a little on bottom of eye ball to draw optic nerve.

Step 14:

Draw optic nerve as shown and label the parts neatly.
