What is Digital Eye Strain?

Digital eye strain is a condition that is being more and more prevalent. It is caused by several factors, including staring at close-up objects for extended periods of time, exposure to blue light emitted by digital devices, and insufficient blinking. People typically blink 12 times per minute, but when they stare at a screen, they tend to blink only five times a minute or less. This means that their eyes are not being lubricated properly. Symptoms of digital eye strain include headaches, blurred vision, light sensitivity, eye irritation, double vision, squinting, excessive tearing or blinking, and dryness. Children may also exhibit symptoms such as irritability, poor behavior and a reduced attention span.
