focusing on eyes with glasses

When taking pictures with a small DOF, is it possible to get the eyes in focus when the subject is wearing glasses? My camera focuses on the glasses, not the eyes...

Also be careful with reflections which can cause the focus on that spot. As MT says.... And are you sure you want that shallow a DOF???Use manual focus, problem solved.

Ignore the sensor. Is the camera the photographer? Or are you??

That's probably my biggest problem. I want to blur out what's behind, but I don't need it so shallow that the nose is out of focus, huh?

Then just use a smaller aperture (higher f in your settings). This will allow you to use a bigger DOF. But you will have to compensate a bit with a slower shutter speed or, if you can not afford that, a higher ISO. Otherwise, as you are letting less light to hit the sensor, your picture will be darker. Aperture priority mode is the best way to have a control of your DOF.

It seems to me you need to get enough DOF so the entire subject is in focus so I don't see how the small difference between the eye and the frame can matter. The nose needs to stick out past the frame.
Taking off glasses is much better anyway. You avoid glare.
With a portrait you can usually control the background so you don't have to blur it.
But if not another option is to deal with it in post processing.

Yes. You want the nose, which is closest to you, in focus as well as the back of the head. Then it doesn't matter if the focus is on the forehead, eyeballs, glasses, or nose tip. Smaller aperture (higher number) - problem solved. Your camera may also have a DOF preview button to see what you're going to get. Read the manual and see if it has one.

One method that works well is to take a shot or two with the glasses off, then the rest with the glasses on. In post process if the eyes are not tack sharp, simply transfer the sharp eyes to the non-sharp eyes image in Photoshop

That is the method Kelby describes in his Photoshop CS6 book for dealing with glare. While it can certainly work I wouldn't describe it as simple. There is another recent thread on that. That isn't the case this OP is concerned about.
The better deal is to just use the one without.
The method described in the other thread for removing glare using Photoshop Elements is sometimes available as a post fix. It requires that one of the eyes have minimal glare. That often happens because of the angle of the reflections. It is much simpler than Kelby's method. It uses the clone tool. Takes a little practice but it is easy enough to undo and try over till you get something you like.

In my opinion the eyes are all important. They must be hyper sharp. The nose will generally be sharp enough and the falloff can begin at the ears...but the eyes are the secret to great portraits....
