Well this is all tied to what word you associate with something. We have all been taught "red" the same I assume and can all identify it correctly (except those who are blind/colour blind). The way we see colours however can differ even in the slightest, all compared to the condition our eyes are in.
For example, you buy a new pair of shoes, you go out to walk in them and even in the slightest they diminish. Small particles eroded and scraped away as you walk. Everything is constantly diminishing even just doing nothing, just at a very slow and minute level. So from when you were born to now, your eyesight has diminished or even sharpened, depending on how you take care of them (they are a biological part of a living thing after all, in the case of the shoes, probably repairing them slightly each day). But most likely after a certain age they do go backwards.
A more quizzical question to ask is, do you see me the same way I do?
Obviously we can go and see each other from a third person perspective but you understand what I mean.
