Digital Eye Strain. Are we managing it correctly or Are we taking enough care? | OOLS |

Updated: Oct 1, 2020

Dr. Jameel Rizwana Hussaindeen begins with the history of the digital eyestrains starting from the 1990s. She talks of the urgent need to focus on digital eyestrain as the world moves online due to Covid-19. The excessive use of smartphones and it impacts on vision-related problems are discussed. She communicates that digital eye strain and computer vision syndrome are similar and emphasizes on the rising prevalence of the condition among various populations. She explains the broad classification of vision-related vs ocular surface-related symptoms when using different digital devices. The ergonomic concerns of using multiple digital devices are discussed along with potential causes of these problems. Dr. Hussaindeen focuses on the assessment and treatment of digital eyestrain for the second half of the talk. She shares some online questionnaires that are quick and handy for assessing the eyestrain for a patient.

She informs us about the online resources our patients can use to improve their ergonomic positioning. Then, she shares recommendations for the presbyopic corrections depending on the different needs of the patients. She talks about the implication for blue-light blocking lenses. She mentions that there is inconclusive scientific evidence about the benefits of blue light blocking glasses for digital eyestrain. She informs us about the scientific evidence and origins of the 20-20-20 rule by Dr. Jeffrey Anshel. She then superficially touches upon the implication of screen time for the pediatric dry eye disease population and the role of optometrists in managing it; early evidence of the effects of yoga to alleviate digital eye strain; the impact of video gaming addiction on vision; and digital eyestrain among the healthcare professionals. Lastly, she shares the results of a survey about digital eyestrain conducted among the live attendees. The survey shows a significantly high number of participants suffering from digital eye strain. This is followed by an interactive question-answer session where she answers some interesting yet commonplace questions most eye care practitioners have while managing digital eyestrain.
