Even better, you absolutely see things in your eye. They're called "floaters". Your brain learns to mostly ignore them.

And if you develop cataracts, your vision tends to "yellow", and you'll be seeing more and more of the lens of your eye, as it becomes less transparent. Cataract surgery (= replacing natural lens with plastic lens) can lead to the operated eye seeing "bright" and un-operated one "yellow".
