Is it normal to have one eye bigger than the other?
Mostly.Normal for most people
Yes. Slight differences in eye size or eyelid shape are common, and most faces aren’t perfectly symmetrical.
A small difference can come from the shape of your eyelids, brows, or the area around your eyes. It may look more noticeable in photos or certain lighting, but lots of people have some facial asymmetry.
If the difference is new or comes with pain, swelling, drooping, or changes in your vision, get it checked. Otherwise, a mild lifelong difference is usually just part of your face.
