Is there a non surgical procedure to fix uneven eyelids, for example, losing weight, or a natural remedy? (Photo)

I believe one of your photos is reversed. Regardless, i agree with you that the eyelids are uneven. You should first consult with an oculoplastics surgeon to make sure there is no underlying process causing the uneveness. Once that has been ruled out, there is tape that i supposed to help with the appearance of excess skin in your eyelids. Best of luck!
