As eye shapes are congenital, you can only turn to make it appear deep set through make-up. Otherwise, you can only have plastic surgery to help you to change the position of your eyes on the skull.
We all know that light change can increase three dimensional senses. Apply eye show according to the rule of light change.
I have to say, that request seems to be very rare and generally speaking, that is not possible. Because deep set eyes are inborn and a lot of people hate that. Thus, I suggest that you try not to do anything stupid about them and try to protect your eyes as much as possible. If you insist on that idea, you gotta consult a plastic surgery.
I always admire people with seep set eyes. However in my knowledge only cosmetics can make that effect, which of course cannot be natural, for it can shape naturally only by gene. You can choose the special eyeliner and eye black to make up your eyes. Or it can be formed with a surgery of bones there,which can make it seemed naturally if you do not mind.
