Creating Eye

I used Photoshop 6.0  to create this Wire. But I am sure you can do it with Photoshop 4.0 and higher versions.

Start with a new document , 312 pixel width and 245 pixel  height with black background. 

Create a new set from the layers menu and create a new layer inside the set. Make a rectangular selection (M) and fill it with blue color

Add noise. Filter > Noise > Add Noise

Amount 25 , gaussian monochromatic.

Filters > Distort > Pinch amount 100

Filters > Distort > Twirl amount -30

Pinch by 100 , twirl by 30 , pinch by 100, twirl by -30 and finally pinch by 100

Make a circular selection (M) inside smaller than the circle.

Create a new layer. 

Right click and choose stroke amount 5. Edit > Stroke

Create a new layer and make a selection for pupil. Fill it with black.

Feather it by 8. Select > Feather , name + Ctrl + D

Invert the selection and hit delete 5 times. Duplicate Layer and select black circle layer at the bottom. Transform its size a little bigger and make it brown with Hue/Saturation with colorize option. Ctrl + U

Hold Ctrl button and click on blue circle layer to get the selection of border. (we will be doing this a lot so better memorize fast that Holding Ctrl and clicking on a layer makes a selection of that layer, but does not choose it) Create a new layer just above blue circle layer and fill it with gray.

Go to Filters > Render > Lightning Effects

Add 2 lights as shown in thumbnails.

Be careful about the positioning and values. You can try to get the best result

Choose hard light from layer blending in the Layers window for the gray circle layer.

Choose Burn Tool (O) and darken the left bottom part to give depth feeling.  Choose blue circle layer and 

Distort > Glass distortion 8 , smoothness 13 texture canvas  scaling %100.

Yep that's it. I left the gray border around because I will need it in the interface tutorial. Below images are improved a little.
