Confusing quote?

It seems to me it says that the actual object changes; or the "object of perception" is not the object itself?

Epicurus Reader

TEXT 68: Sextus M 7.203-16 (247 Usener)

But rather [I would say] that [the vision] tells the

truth, since when the object of perception appears to it [as] small and

of such a shape it is genuinely small and of such a shape (for the edges of

the images are broken off by the movement through the air), and when it

again appears big and of a different shape, again it is in a similar manner

big and has that different shape-

the object being, however, now not the

same in the two cases. For it remains for distorted opinion to think that

the same object of presentation was observed from close up and from a

distance.

The "object of perception" are the atoms impacting the eyes, and thus are not the object itself. Thus, they are different than the object itself, and are relayed to our minds as they are, so the vision is relaying to the mind what it perceives, which is indeed different from the actual object far away.
