Step one, mask off the area you want with clear tape.

Step two, mask off the area of clear tape you want to cover.

Step three, spray the area you're looking to make red with a few coats till its the desired level of 'red'

Step four, decide if you like it or not. If you do, remove tape and repeat. But if you don't like it, just peel the tape off and goo gone the lens. No harm no foul.
