The most effective predictable treatment for upper eyelid hollowness is upper eyelid/brow filler injection. See following video and website link. Expertise is important. Another option is fat injection but less predictable.

Upper eyelid hollowness is a dramatically underappreciated, yet incredibly important component of aging in the eyelids. With normal aging, our upper eyelid fat pads tend to retract and expose this upper lid hollowness, those with “deep set eyes“ are especially prone, and unfortunately old-school upper eyelid surgery that is overly subtractive can artificially create this hollowness early, actually looking worse than it did before surgery - the before and after photo in the link below resulted from overly subtractive upper eyelid surgery with another surgeon, and you can see the results after revolumization of the upper lids. Correcting this hollowness can happen with fat or filler injections into very specific planes of the upper eyelid, or transposing and rearranging the upper eyelid fat pads to provide fullness, as you see in this surgeon’s view video, borrowing the excess fat to move into the areas lacking fullness!
To ensure you are receiving the highest level of care, seek out a modernly trained, new-school dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these “core four” cosmetic specialties. Membership in organizations like the American Academy of Facial Plastic and Reconstructive Surgery help to identify a highly trained surgeon.

Thanks for your photos and questions
I agree that fillers would be the best way to start.  With the eyes, you want to be conservative because although fillers are very safe products, you don't want to inject too much or have poor distribution of the product.  You may need several rounds of treatment until you get the result you're looking for.  Fat is another option, but you should be sure that you like the appearance with something temporary before moving to something permanent.
