The introduction of digital gadgets has resulted in a marked rise in screen time, prompting worries about possible effects on binocular vision. In order to better understand the connection between extended screen time and binocular vision abnormalities, this study focuses on accommodative dysfunction, convergence insufficiency, and asthenopia symptoms. The increased use of computers, tablets, and smartphones has changed the demands placed on the eyes, possibly putting the visual system under stress, particularly when these devices are used continuously for lengthy periods of time ^[1].

Key topics explored include the impact of extended screen me on visual acuity, accommodation, and the development of symptoms such as eye fatigue, dryness, and discomfort. Additionally, attention is directed towards exploring the modulating influence of environmental factors, such as ambient lighting conditions and display characterise cs, on the severity and manifestation of digital eye strain ^[2]. After the COVID-19 pandemic every individual especially corporate worker, students are involved in their works with the digital devices like phone, laptop. They are spending lot of times with their devices.

Children’s who are spending time more than 4 hours with smartphone, can face eye strain, Asthenopia, blurred vision, asthenopia & digital eye syndrome (DES). A study conducted by researchers whereas using smartphone daily basic can increase the myopia progression 30%. In the country Korea, USA & UK, using digital game along with addiction of video game can faces mental problem in the population that is enlisted by World Health Organization (WHO).

The findings revealed a trend toward convergence insufficiency as those with increased screen usage (6+ hours/day) had a substantial decline in NPC and PFV ^[3]. Furthermore, 40% of these subjects showed signs of accommodative disorder, including latency in accommodation and decreased Amplitude of Accommodation. Sixty percent of the high screen time group reported experiencing increased symptoms of digital eye strain, such as headaches, blurred vision, and eye fatigue ^[4]. This finding further connects extended screen use to problems with binocular vision. According to the results, extended periods of screen usage may increase the likelihood of binocular vision abnormalities, including accommodative dysfunction and convergence insufficiency. Modifications to ergonomics and frequent visual pauses are examples of preventive strategies that might lessen these impacts.

Nevertheless, there are preventative steps that can lessen the harm that computers do to our eyesight. Some of them include having a sufficient viewing distance, appropriate lighting in the workspace, anti-glare eyewear, taking 5-minute breaks every 20 minutes of using digital devices, or adhering to the 20-20-20 rule. In conclusion. Long-term use of video display terminals has been linked to a number of ocular illnesses, so in the modern world, it's essential to keep in mind steps you may do to reduce your risk.
