Unless you lost eyesight on one of the eyes at least, you may have no idea what an artificial eye is, let alone its necessity and importance. An artificial eye is not intended for recovering, correcting or maintaining vision. When one lost vision on one of the eyes, he or she wants to give a normal impression to others as if both of the eyes are in the same healthy state. With an artificial eye, he or she can overcome the complex associated with the 'one-eyed' image in the society and have nice interpersonal relationships based on his or her regained confidence. Thus there is no overemphasizing the importance of artificial eyes to those who lost eyesight on one of the eyes.
