When the light is strong, the blackout curtains are hanged at the same time as the ordinary jacquard curtains.
Although it is winter, the sun's rays are very strong on sunny days, and because the angle of the sun is larger in the winter, and the windows of the office are floor-to-ceiling windows, it is very big and really feels dazzling. This also provides a good environment for testing.

The last thing is: if you don't want to sleep late, don't use blackout curtains.
