What Causes Eye Strain?
In many cases, eye strain symptoms are caused by looking at something for long periods without blinking. This can cause the eyes to feel dry. Eye strain from looking at a computer is no different from strain caused by driving or reading for hours. Sitting near a vent that is blowing hot or cold air in a person’s face also can make eyes dry out more quickly.
An incorrect prescription for glasses or contacts can cause blurriness, which can increase the feelings of eye strain, Dr. Barber said. Working in an environment that is too bright or not bright enough also can cause visual discomfort.
“If we have poor posture when we do tasks, it can cause neck, shoulder and back pain, which can add to the discomfort we feel and some people may attribute it to eye strain,” she added.
