Double eyelids become single eyelids in photography

That’s a problem with your camera angle. Generally, it won’t look out of shape. If you put the frame of the camera’s viewfinder’s sensing area on your face, it will improve based on your face. If you take the picture with your heart as the center, your face will be blurred and look like a single eyelid. It will be better to find the angle and position of the picture.
