Can the eyeballs shrink or become more deep set as a teenager becomes an adult and if : how to prevent it?

So, Ive heard that the eyes can get more deep set with age but I am only 18 years old and I think my eyes have become smaller and more deep set than 4 or so years ago. I have always had deep set eyes but now I feel like theyve sunken even deeper and that my eyeballs 've become smaller as well. My eyes aren't hooded and my eyebrows aren't low, there is now excess skin whatsoever, I just think my eyes or eyeballs in general are smaller then when I was 14. Could that happen to a healthy person?
