My eyes are fairly asymmetrical. I slightly tilt my head to compensate. Will my tilt/crooked glasses worsen it as I age? (Photo)

Agree with Dr. Steinsapir's comments. Everyone is born with asymmetries of the face caused by unequal bony and soft tissue. As we age, we lose facial volume, and asymmetries become more pronounced- especially around the eyes. In your case, we note bony socket asymmetry as well as brow, cheek and eyelid asymmetry. While fixing all these asymmetries would be overly aggressive, risky, and not appropriate, there are some maneuvers that can effectively hide the asymmetry. A mild amount of ptosis correction on your right side would help improve your symmetry. This is a low risk procedure and would be very appropriate do your situation. The surgery takes less than ten minutes and can be simulated in the office with a phenylephrine drop. Hope this is helpful for you. Good luck to you!

These head tilts tend to be pretty stable over time.  There is no surgery that is offered to correct these unless there is bothersome torsional double vision.  If you have no vision issues, my advise is to ignore the issue and accept that this is normal for you and understand that although you are aware of it, no one else is likely to notice the issue.
