Low Humidity: There are many reasons including low humidity as in an air-conditioned room or airplane then the eye gets dried. This situation may also occur if there is a lot of wind in your eyes.
Too Often Screen Time: When you stare at a computer or phone screen for lengthy periods of time, you don't blink as much, thus moisture does not circulate in your eyes and they stay dry.
