See following link for more information. The inherited lower eyelid retraction with sclera show is due to the eyelid position in addition to the eyeball position. Different treatment options exist.
There are a few things to consider. First of all, a good ophthalmology exam would be warranted to ensure that you do not have any medical conditions that are causing your problem, especially if it is something that has changed or worsened with time. Sometimes thyroid issues can lead to these findings, for example. Also, once stable, surgery to raise the lower lid is the best option, but sometimes fillers can be used to temporarily raise the lower lids too. It is really hard to say what the best option would be for you without an in-person consult, which I'd highly recommend. I don't know how old you are, as you state you are young, but sometimes increased scleral show can also cause trouble closing the eyes and can ultimately cause damage to the eye, so I do encourage an evaluation at the very least! Good luck!
Inferior scleral show has absolutely nothing to do with race or ethnicity. When the chin is tipped down and the eyes are looking up, it may be totally normal to have scleral show. There are factors that make this scleral show greater - prominent eyes, shallow eye sockets, myopia/ near-sightedness, flat maxillary bone, thyroid issues, and heredity. Inferior scleral show is less noticeable with head held up and looking straight ahead. When the chin is tipped down, the eyes naturally rotate up to see straight ahead - revealing some inferior scleral show. An Oculoplastic subspecialist could evaluate and discuss non-surgical and surgical options with you. Best wishes.
