I am seeing purple spots out of the corner of my eye after coming back from a dentist appointment and having the right side of my face numbed. The are quite vibrant and seem to appear mainly when white surfaces are in the corner of my eye. For example, walking around my house on my white carpet and looking forward, they appear on the carpet in the corner of my eye but fade when I try and look directly at them. They tend to linger, however, when I directly look at them which is what concerns me. I do wear glasses and contacts. I am a 15 year old female of healthy height and weight. I m just wondering how serious this could be. Thank you.
