Habitual glasses wearer
I wear glasses when I'm not wearing contact lenses. I'm likely to wear contacts for daytime travel but I will have taken them out by the evening or for a long-haul flight. So if my passport photo showed me wearing glasses and I wasn't currently wearing any during the border checks, I'd have the same problem. After some thought, I decided it would be simpler to remove my specs if necessary than have to hunt for a pair in my baggage to put them on. I also considered the unpleasant scenario of being killed during international travel and the challenge of identifying my body until someone found a pair of glasses to shove on my dead face.
