Minor ptosis in one eye (Photos)

I'm 20 years old, and have noticed a slight drop in my left eyelid. It's not something that was there when I was a child, and I've heard Ptosis can get worse with age. It's not massively noticeable, but is noticeable on pictures once pointed out. Is it something I should look at getting fixed in the future? I'm not entirely sure about it, as I like my eyes as a feature, yet I feel it might be something I'm worrying too much about.
