>>2892463er.. if thats the same lens you have been showing in the other photos ... they look different....so I'd suggest you need to stop with the feeble light source and get a proper light on it before you can really see or record photos of anything worth evaluating.
Put the strongest light source you can find behind the lens, look through the lens from the FRONT from all different angles, moving the light source at the same time will help you find the best viewing angle for each section of damage/crud.
Obviously..shielding any light escaping from the sides will hep you see and photogtraph what you see.
And fyi, that last image shows scratches.
