With the growth of internet usage among older people, concerns about “older adults' internet addiction” frequently appear in media and research. To achieve a comprehensive understanding of “older adults' internet addiction”, this study discusses the concepts, phenomena, and impacts of “internet addiction”. “Internet addiction” is characterized by three features, including “excessive use”, “damage to primary activities and social functions”, and “persistent and prolonged states”. Existing discussions and studies mainly focus on the single dimension of “excessive use”, exaggerating the issue of “older adults' internet addiction”. Data from the “Survey on the Digital Divide and Integration of the Older Adults in China” show a low proportion of older people who are addicted to the Internet. Currently, the main challenge in the internet lives of older adults is how to deal with the “digital divide”. To enhance the internet accessibility and proficiency of older adults, we suggest upgrading the intelligent device hardware, software, and functions for their convenience and providing guidance on smartphone use for older people. This will help older adults benefit from the development dividends in the internet era.
