Abstract: The study aims to assess the prevalence, risk factors and impact of smartphone use 
on vision in the age of digitalization, and to formulate behavioral recommendations for using 
mobile digital devices. A literature review was conducted on the topic using Google Scholar, 
Pubmed, CrossRef and free search. The results show that when we stare at a phone screen, 
because it is much smaller compared to a computer and the screen is at a much closer distance, 
it results in a greater visual strain and a greater strain on accommodation and convergence. 
Smartphone technology is based on blue light and there is a high probability of vision damage 
due to the shorter wavelength of light when used for a long period of time. Eye problems 
associated with smartphone use such as eye strain, double vision, redness, tearing, and blurred 
vision have been described in the literature. These disturbances were mostly observed in people 
using smartphones for more than 3-4 hours a day without a break. Cases of transient vision 
loss have also been reported in patients who looked at a cell phone in the dark for several 
minutes. From most studies, we can conclude that we need to set limits on screen time and 
mobile device use before bed.
