Well here's my tutorial on how one sharpens eyes in Photoshop. Here are the steps and screen shots to show how its done. This is about as easy as one can get. Later on, if there's any interest, I'll publish method two.
Step 1. Get the photo into Photoshop. Crop and do any preliminary post processing. Here is what the eyes look like at this point:
Step 2: Use Filter | Sharpen | Unsharp mask to sharpen the image however you want, but pay attention only to the eyes in the preview window. Now we are at this point in the process:
Note what I've done. I've clicked back one step in the History Palette (1) and I've placed a checkmark (2) by the step that contains the sharpening (the step after the one I've moved back to). What we have at this point is the shot without the sharpening but we've set the target of the History brush to be the step that contains the sharpening.
Step 3: Grab the history brush (see photo below) and use it to paint over the eyes and brows and anywhere else you want sharpness. Use a soft brush.
Here is what this looks like:
Compare the eyes between the first photo above and this last one.
Well that's the process. Easy wasn't it.
Now do the exact same process but in step 2 use some form of Blur and do the same thing for the face.
Here's the final photo:
