Did you know that an average person blinks around 15-20 times per minute, which means we blink about 1,200 times per hour, 28,800 times per day, and 10,512,000 times per year! However, when we are staring at a screen or something that requires concentration, we blink less frequently, which can lead to eye strain and dry eyes.
