Certain professions make dry eye symptoms difficult to avoid.

Vets are constantly exposed to animal hair and allergans.

Surgeons may need to hold their line of sight without blinking.

Working in front of a computer all day, or spending a lot of time looking at a digital screen means you are at increased risk for the onset of dry eye.

If you don’t seek help for your dry eyes you may develop:

  • Eye infections. The lack of tears is what a main problem and as your tears are anti-bacterial any decrease raises the risk of infection
  • Damage to the eye’s surface, including scarring on the surface of the eye or intense inflammation (swelling).


Why do computers cause dry eyes?

If you’re like most people, you spend much of your day staring at a computer, tablet, or smartphone both at work and on your own time.

Over 60% of adults use a digital device for at least 5 hours a day.

Large amounts of screen time can cause eye dryness and discomfort because our eyes are being challenged to focus on very close objects for long periods of time.

And you may have significantly more discomfort if you already have an eye issue, such as mild dry eyes or allergies.

How do computers cause dry eyes?


According to a recent study people blink more than 50% less when using a computer.

On average, people blink only 5 times per minute when looking at a screen, when they usually blink 10-12 times per minute while doing other activities.

Blinking allows tears from our glands to spread across our eye’s surface. Tears are essential for keeping our eyes moist and healthy, so blinking less frequently will cause the eyes to feel dry and irritated.


When we’re focused on a task, it’s easy to overlook some of the other signals our bodies send us such as drinking regularly for hydration. Drink plenty of water while surfing the web to avoid exacerbating dry eye symptoms.

Why do dry eyes cause blurry vision?

When the eyes become dry, most often the very first noticeable sign is blurry vision. This occurs because the tears are unable to adequately coat the surface of the eye, resulting in a rougher surface that disrupts visual comfort and clarity.
