Hello everyone, I'm new here

Right now I'm playing Freespace 1 campaign with FS2Open 3.6.10 and MediaVPs and I'm going to play FS2 campaign soon.
I know there's latest 3.6.12 version but I'm too lazy to download and install everything again right now

I have one question regarding Sun glows and flashing - it is possible to completely disable it?
When I'm playing missions and performing combat sun's are blinding me hard.
I know this effect adds some 'immersion' to gameplay but unfortunatelly my eyes aren't very healthy nowadays and just hurts after 10 minutes of fighting and seeing flashing surface of sun.
Right now I'm just trying not to 'look' at suns ingame, but I'm just curious if it is possible to completely disable sun glow and flashing.
I'll appreciate any help
