How many times does a person blink his eyes in a day ?

 On average, a person blinks their eyes around 15-20 times per minute, which amounts to approximately 1200-1500 times per day. However, this can vary depending on factors such as age, health, and external stimuli like light and screen time. Some studies suggest that people blink less frequently while reading or using electronic devices, which can lead to eye strain and dryness.
