Having blackout curtains is not bad for sleeping habits, and can help you fall into a deep sleep. Besides, a blackout curtain is better than a sleep mask, there is no stress on the eyes.
The blackout curtain provides room darkening and it is necessary for people who work at night and sleep during the day.
When you purchase blackout curtains, you’d better select physical shading curtains (triple-weave fabric, lining for shading) rather than chemical shading curtains (adding a chemical coating to the curtain fabric).
