A sleep mask is the most reliable way to create darkness regardless of your environment. What separates good from bad sleep masks: 3D contoured design (flat masks press on eyeballs, contoured masks leave space for them — this is the single most important feature), nose flap (prevents light from leaking through the gap between the mask and the bridge of the nose), adjustable strap, breathable material that does not trap heat. Types of sleep masks: flat cotton/polyester (cheapest, most common, least effective, presses on eyes), 3D contoured (slight dome over eyes, best for most people), buckwheat or weighted (filled with buckwheat hulls, molds to face, heavier, some find soothing), silk (luxury option, very soft, not as effective at blocking light).
