How Excessive Screen Time Is Linked With Dry Eye Syndrome? - Dr Naresh Alreja
Dry eye syndrome (DES) is an eye condition characterized by dry, uncomfortable, red, itchy eyes, and can be caused by several factors: poor quality tears, insufficient tears, allergies, environmental irritants, and spending excessive time staring at a screen. Left untreated, DES can cause corneal damage and scarring, and rarely permanent vision loss.
In today’s tech-driven world, screen time has increased drastically. Blinking is an important physiological process to keep one's eyes lubricated all throughout the day. With excessive use of computers, mobile phones, and other display devices with a screen, there is a decrease in the number of eye blinks, incomplete blinking, evaporation of tears, and subsequently, dry eye disease.
If you’re like many people, your eyes are on a screen throughout the day; spending time staring at a computer, a tablet, or a smartphone at work and in your own time, you are prone to develop dry eyes. The most common type of dry eye disease is an evaporative type, and the use of screens is especially important in this group.
Studies also suggest that prolonged screen time may reduce tear production. When you're focused on a screen, you may not blink as often, leading to decreased tear production. This can result in dry, irritated eyes. Our blink rate is reduced by 66% when staring at a digital device’s screen. This finding is significant because blinking less frequently increases the risk of developing dry eye syndrome.
