Blinking is a natural and essential function of the human eye that plays a critical role in maintaining eye health and comfort. In our screen-dominated world, many of us spend extended periods staring at computer screens and smartphones. During these activities, our blink rate decreases significantly; studies show that individuals blink approximately 60 percent less when using a computer.

Normally, we blink around 15 to 20 times per minute, but this can drop to as few as 5 to 7 times per minute when focused on a screen.

Reduced blinking can lead to a variety of eye problems, including what are commonly known as "office eye syndrome" or "digital eye strain." Over time, this can contribute to chronic dry eyes.

Blink Better: Ease Eye Strain and Dryness

Regular, conscious blinking and periodic breaks are simple but effective ways to ensure our eyes remain healthy. EFS Blink Tracker's real-time feedback helps you adjust your behavior and makes sure that you blink at a healthier rate.

The app runs in the background, is lightweight, and works with basic consumer-grade webcams. It reminds you to take regular breaks from the screen and collects valuable diagnostic information that you can share with your eye care professional.

Blinking and Eye Moisture

One of the primary functions of blinking is to keep the eyes moist. Every time we blink, a thin layer of tear film is spread evenly across the surface of the eye. This tear film is crucial as it provides essential moisture, nourishes the cornea, and helps wash away any debris or irritants that may have settled on the eye's surface.

The tear film is composed of three layers: the lipid (oil) layer, the aqueous (water) layer, and the mucin layer. Each blink ensures that these layers are spread across the eye, maintaining a stable and healthy environment necessary for clear vision.

When we blink less frequently, the tear film is not replenished as often, leading to dry spots on the cornea. This can cause discomfort, blurry vision, and a sensation of grittiness or burning in the eyes. Chronic dryness can also lead to more serious issues like inflammation or damage to the corneal surface.

Consequences of Infrequent Blinking

Office Eye Syndrome: This term refers to the discomfort and eye issues experienced by people who spend long hours working on computers or other digital devices. Symptoms include dryness, irritation, redness, and blurred vision. Over time, this can contribute to chronic dry eye, a condition where the eyes are unable to maintain a healthy tear film.

Gamer Eye Syndrome: Similar to office eye syndrome, this condition affects individuals who spend long hours gaming. The intense focus required in gaming often leads to a reduced blink rate, exacerbating symptoms of dryness and eye strain. Prolonged exposure to screens, especially in a low-light environment, can further strain the eyes and exacerbate symptoms.

Importance of Regular Breaks

To mitigate the effects of reduced blinking and prevent digital eye strain, it is essential to take regular screen breaks. The 20-20-20 rule is a popular and effective strategy: every 20 minutes, take a 20 second break and look at something 20 feet (ca. 6 meters) away.

This practice helps relax the eye muscles and encourages blinking, which in turn keeps the eyes moist and comfortable. EFS Blink Tracker monitors the times you spend looking at the screen and prompts you to take a break when necessary.
