DRAWING TUTORIAL :-HOW TO DRAW EYES
I made this tutorial to show the different steps that I take in drawing a realistic eye. There are many different methods I started with an outline of the eye. I have just a basic line drawing at this point. I also marked where some highlights in the eyebrow and eye will be so that I don't forget
about them later
Step 2 I began darkening a couple of the darkest places in the drawing. Don't be afraid to go too dark in these areas. It won't matter. In fact, it will probably help the drawing in the end because it will add contrast. I used a 3B pencil for these areas pressing fairly hard but not hard enough to dent the paper.
Step 3 I started shading the eyelid and surrounding areas. shaded with a 3B with not a lot of pressure.
Step4I am drawing skin so I want it to be believable looking
step 5 I continued laying down tone with my 3B pencil paying close attention to small details on my reference photo. I blended some tone from the inner part of the eye into the eyeball too. Don't make the mistake that eyeballs are white. They are not white unless light is perfectly reflected off of them. Compare the highlights in the eyes to the eyeball tone. You will see that they are different.
Step 6 I began working on the iris of the eye on this step. This takes alot of patience and observation. Every eye is different so there is no universal way to approach this step. Just look close at your reference and draw what you see. 
Step 7 I was half-way done with the iris at this step. I looked for tone variations in the iris and drew what I saw
Step 8 The iris was done at this point and I came across a highlight in the eye. Keeping the highlighted area clean is crucial to attaining a wet, reflective look. It should be the lightest part of the entire drawing. Shade around this area. If you want the highlight more brilliant, lay down more
tone around it
Step 9 I shaded around the highlights. Now the eye looks glossy and wet
it slow and start with some basic thinking. This step I just laid down some 3B paying attention to tone variations in the brow. I noticed that the left and bottom parts were darker than the rest. Also, I encountered another highlight that I had marked earlier so I shaded around it. After I was done toning the area, I took my 3B mechanical pencil and started making quick little hairs around the area.
Step 11 I continued working on the brow, adding tighter details when I noticed them. Some lighter hairs that I overlooked were added here too using a sharp cut eraser. I added some tone to the skin lying underneath the hairs too.
Make sure you pay attention to tone gradients, transitions from light to dark. I looked close for some of the creases underneath the eye too and added them. As I blend over these creases I darkened them in again.
Step 13 More work under the eye and on the eye lashes. There were alot of lashes that were highlighted, not completely white though, so I needed to draw around them and shade them slightly. I worked on the wrinkles under his eyes too.
Step 14 Almost done now. I blended some of the darker areas into the lighter
Step 15 This is the final step. It's basically just cleaning up the drawing and adding small details if you'd like. I added alot of dots all over the drawing to suggest some pores and imperfections in the skin. I also darkened around the highlights to make them shine more.
All of my tutorials are free, I don't ask for anything in return.
I hope this tutorial has helped you in some way or another. I can explain how I do things all day but the basic idea of drawing is to just understand how tones flow and to train your eye to see what others don't see.
