I put up a blind in my office window. It’s just a simple white roller blind that cuts 30% of the light. It solves the problem that around late afternoon, the sun shines directly in and makes it unbearably bright and hot. Not every day, clearly, this is England, but often enough to be annoying. I can close the curtains, but then it’s dark. Now, however, I can have daylight without that death ray effect.
