smudge inside T1 lens?

I’ve had this T1 for 3 years now(original owner) and never really noticed this until I found another strange flaw with it yesterday. What looks like a finger smudge inside the lens. Any idea how this might have happened?

Here’s the 2nd problem which is a red dot reflection in the unit when it’s powered both on and off and looking into light

Above picture is when powered off

I don’t know about the smudge, but the reflection is normal when there’s a very bright light source in front of the optic.
