Ring lights help in this area as well and are cheap enough nowadays.
Or a desk lamp pointed at the wall behind your laptop if you’re at a desk.
Thanks to ring lights and Youtube, I'm pretty sure my kids are going to grow up thinking there's some variety of eye-color that features a bright white ring in the center of the pupil.
I HATE ring lights. Makes everybody look like they're being abducted by a UFO or something. Or they're robots. They need some diffusion or something.
Several times I've opened a white page full screen on my monitor while doing an interview via Phone or Laptop. That plus the over head light being on but not being in the view helped quite a bit.
