Probably the most simple, inexpensive and easy way to ensure that you have darkness when you are trying to sleep is to use a sleep mask (also known as an eye mask, sleeping mask, and sleep eye mask).
Sleep masks are made of light-blocking material that cover your eyes and fasten around your head. They are capable of blocking nearly 100% of light. Most people find them to be effective and easy to get used to wearing. However, if your initial impression is that you don't like wearing one, don't give up too fast. Try wearing the mask a few nights to get used to it and to find the right adjustment of the strap.
Advantages of a Sleep Mask
- A sleep mask provides a quick, easy way to block light from reaching your eyes.
- It is inexpensive compared to other ways of blocking light, such as window treatment.
- You can take it anywhere you may want to get sleep and block light.
Disadvantages of a Sleep Mask
- While generally comfortable, it can take getting used to, and some people for whatever reason cannot get used to wearing one.
- Like anything you wear on a regular basis, it will need washing and can wear out.
- It can be misplaced.
- While it effectively blocks light from reaching your eyes, it does not stop light from hitting your skin as light-blocking window treatment can do. Light hitting your skin during the night from a street lamp shining through the window, for example, may cause your body to think it is morning and want to start the day. (However, if you have light in your bedroom at night, your blankets may do an effective job of blocking most light from reaching your skin.)
