I have purchased levelor black solar shades with both 10% openness and 5% openness. We have large 8x4 windows in our living room with direct sun glare in the afternoon/evening. The 5% openness still lets in too much sun and we have to squint. I am trying to decide whether to purchase a 3% or 1% open solar shade next. Has anyone experienced too much direct sunlight glare coming through a black 3% open solar shade?
