A recent study published in the journal, Sleep stated that wearing an eye mask while sleeping helps being more alert the next day.
The researchers found that blocking out as much light as possible boosts a person's alertness the following day.
The experts from Cardiff University conducted a series of experiments involving a total of 124 volunteers who were asked to sleep with and without eye mask for the same number of days to record their experience.
The participants took 3 tests to measure brain power and in the first 2 tests it was revealed that people performed better on cognitive and reaction time exercises during the week they wore eye masks. Though eye mask had no effect on the third test to examine motor-skill learning.
The team also noticed that masks helped people to spend more time during the deepest phase of sleep which is believed to be important for processing new information and strengthening memory.
