I have had several vortex binos, upgrading as money allows. I recently purchased a pair of razors 10x42 and so far I am pleased with them, very clear to my eyes. However, when looking through windows with them they are crazy blury. All of my less expensive models (crossfire, dB, and viper) were pretty clear through my house and car windows. What’s causing the razors to be so blurry through windows? Is it that the picture is so much clearer it’s picking up and magnifying the dirt/smudges on the glass?
i understand it’s a weird question, not a big issue. Just wanted to see if anyone had an answer I hadn’t thought of.

Window glass isn't coated and doesn't transmit light the same as coated optics. Depends on the coating used if it will be clear through glass or not. All coatings don't transmit light the same either with some color bands being subdued and some being accentuated.

Or you have really dirty windows.
