Scratched headlight

[TBW]

Is it OK to have a headlight polished? Got a couple of scratches on one of mine and wondering whether to have them professionally polished out?
What are the downsides?

thanks!

Thanks guys - someone else is paying (their fault) so not going to go down the DIY route!

Anyone know if they are coated with a UV protection agent?!
