Increased exposure to blue light via digital screens can negatively impact ocular health by contributing to a condition known as Computer Vision Syndrome (CVS) or digital eye strain.

For example, If a person's TBUT is 15 seconds which is thought to be normal and his blink interval is 20 seconds, here TBUT is less than IBI, so ocular protection index will be less than 1.0 and is abnormal. Since computer use affect blink rate, OPI is a clinically relevant in detecting dryness related to computer vision syndrome. [11]
