Why Does Light Bend Around Your Finger?

[42Physics]

Why does light appear to bend around my finger when I have it close to my eye? Try it with your phone/tablet. Keep the object about 2-3 inches away and put your finger to your eye, and watch the letters bend. I am aware of the property of light with gravity and everything, but why is it so noticeable around a 3 inch human finger? Is it a trick of the eye or is it real?

Do you have both eyes open? If so, you're seeing your finger with one eye and your phone with the other eye.
