My left eye looks smaller than my right eye. (photos)

My left eye appears much smaller than my right and it is affecting my life. I cannot take picture while looking at the camera as my left eye appears much smaller and makes me look horrible. I have tried going to the optometrists to get my eyes checked and vision tested. My right eye has blurry vision whereas the vision in my left eye is much clearer, although the opticians say there is nothing wrong with my eye but it becomes red very easily and feels uncomfortable, I've also been given eyedrops
