Yes, eye exams are recommended for everyone, regardless of whether you think your vision is fine.
Some vision problems develop so slowly that it is difficult to detect changes. More importantly, eye diseases like glaucoma can develop without causing any noticeable symptoms; you may not realize there is a problem until the disease has advanced to the point where it may permanently affect your vision.
Having routine eye exams with a qualified eye doctor is the best way to defend yourself from glaucoma and other diseases that can lead to irreversible vision loss.
