What is the issue -- why have my eyes changed so much in 5 years? (Photo)

35 years old is halfway between being 30 and being 40.
Five years is definitely enough to have a significant impact on somebody’s face.
Look at a high school yearbook and see the difference between the freshman and the seniors.
Half a decade is a significant chunk of change to change someone’s facial appearance.
If you’re unhappy with the look of your eyes, then consider consulting with plastic surgeons, facial plastic surgeons, or oculoplastic surgeons in your community to consider eyelid surgery.
Of the pictures you included I think the second picture is the most informative. Based on that I don’t see a strong indication for surgical intervention.
Your face and eyelids look typical and normal.
Accepting the aging process can be challenging for some people.
I don’t see a clear indication for surgery and this means that surgical intervention may not have the desired effect.
Making a good assessment regarding eyelid position is slightly dynamic since changing the visual gaze has a big impact on the eyelid position in relationship to the iris and pupil.
Pictures can be helpful, but they need to be taken correctly with neutral facial expression, and always with a forward gaze.
With a downward gaze, your upper eyelids are going to look like they sit too low.
