Upper eyelid ptosis and lower eyelid retraction
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.
You should wait until at least 18 years old. You have upper eyelid ptosis (droopy), upper eyelid/brow hollowness, and scleral show. Filler/fat injection in the brow will help with the hollowness. The scleral show is a more difficult problem and there is no easy answer. See an oculoplastic surgeon for evaluation.
I would be very conservative, as canthoplasty can leave some visible scarring and symmetry of the lower lids can be a challenge. I would defer surgery for at least 10 years, and then get a couple of opinions from a plastic surgeon and an oculoplastic surgeon. There are different tests to be done in person that would help determine if you are a candidate for surgery, period.
