The study's objectives were to evaluate the various ocular symptoms on a digital screen, develop healthcare recommendations to lessen user eye discomfort, and contribute to the development of digital devices that are less likely to cause visual and ocular pain in general users. A review of reports released between 2001 and 2022 was finished, and a literature search utilizing PubMed, Google Scholar, and original articles released up until January was conducted. The terms "Digital display screen”, "Blue blocking filters”, "Digital eye strain”, and "Video display terminal" were utilized as keywords. We searched for papers on the impact of binocular vision using the terms "accommodation”, "convergence”, "vergence”, and "phoria." To identify the impact on the ocular surface, the phrases "tear film”, "blink rate”, "blink amplitude”, "blinking”, "dry eye”, "tear function”, "tear amount”, and "tear break-up time" were employed, the research on digital screen use conclusively reveals a rise in ocular and visual symptoms like headaches, eyestrain, dry eyes, irritated eyes and one of the reasons being is incomplete blinking. It is unknown if using several devices has a higher impact on the visual system and ocular surface, and it is also unclear how switching between screens would affect accommodation and vergence.
