Its hard to tell from the picture but from far it looks to be either Screen shades or Bamboo blinds. In this type of situations i would actually recommend going with a Cellular shade . It will still let in a nice amount of light but would definitely cut the glare on you computer screen .

I don't recall what was used there, but perforated roll screens would be a good solution.
