If this is your first time sleeping with an eye mask at night, it may take some getting used to. If this applies to you, we have heard success from many customers that slowly increasing wear time was beneficial. Start with an hour your first night, then two, and so on. After one to two weeks, you should have no problem sleeping through the night with your Blinkjoy mask. Even if your mask takes some getting used to, stick with it…your eyes will be happy you did.
