I agree that you should wait till you're at least 18, but if you are in your "Late Teens", that means you are probably already there.
You have upper eyelid ptosis, which makes your upper eyelids seem a bit hollow as well. An upper eyelid ptosis repair, can also improve the hollowness of the upper eyelid below the eyebrow. I have posted a link below to show you an example.
Your inferior scleral show is a sign of lower eyelid retraction that can be very nicely improved with a graft on the inside of the lower eyelid. I have also posted photos of that in my photo gallery in Realself.
Seek an oculoplastic surgeon.
