is it possible that a person has both myopia and farsightedness?

-I don't understand this,as myopia and farsightedness are two very dissimilar eye conditions to me. -Obviously such a person will need bifocals. .

It is impossible for one person to have myopia and farsightedness in the same eye ,but possible in different eyes . The fact that people need bifocal glasses doesn't mean they are both farsighted and nearsighted , it is because the eyes have insufficient accommodation to change focus from distant to near. It is common for people over 40s to wear bifocals if they have presbyopia as their eyes have difficulty in automatically changing focus from seeing at one distance to seeing at another distance .
