A person who needs glasses is either near sighted (meaning their eyes can't see things further away) or far sighted (meaning their eyes can't see things close by), so when light enters their eye, it either reflects the light in the front the cornea if the eyeball is too short or behind the cornea if the eyeball is too long. Either way the light doesn't reflect in cornea properly, and the image is blurred. Glasses are designed specifically to change the angle that light comes in so that it is reflected correctly, and are either convex or concave (shaped inwards or outwards).
