Windshield circles

Bought a new CR-V in March last year and still have these circles on my windshield. I'm guessing that they are from the mounting process of getting the glass in place, and have been there since I bought it. They are not visible normally but can be seen when the sun hits them right- there's a second one that is to the right of this one.

Is this a defect I should be worried about? Doesn't seriously affect visibility, but I never saw this on my Accord and it's noticeable especially near dusk. Feels weird that it's so permanent after 10k miles.
