Computer-related dry eye
Quick answer
Prolonged screen use — computer, phone, tablet — is one of the most common causes of dry eye today. When we focus on a screen, we blink up to 60% less than normal, which drastically reduces how often the tear film is refreshed over the eye.
Prolonged screen use — computer, phone, tablet — is one of the most common causes of dry eye today. When we focus on a screen, we blink up to 60% less than normal, which drastically reduces how often the tear film is refreshed over the eye.
Many screens are also positioned at eye level or above, forcing the eyelid to stay more open than usual, increasing the surface area exposed to air and, with it, tear evaporation.
If your job requires many hours in front of screens and you notice burning, visual fatigue, or blurry vision by the end of the day, this is likely the type of dry eye you're experiencing.
