Purpose: The purpose of this study was to understand the lived experience of suffering from vision loss in adults with acquired visual impairment in South Korea. Methods: A phenomenological approach was used to inquire about the lived experience of suffering in 10 adults with acquired visual impairment. The data were collected through individual in-depth interviews. All interviews were audio-taped, and verbatim transcripts were made for the analysis. The data were analyzed using Colaizzi’s phenomenological method. Results: Four theme clusters were extracted from the analysis. They were as follows: ‘blindness as nightmare becoming reality,’ ‘locking in the curtain of darkness,’ ‘living with wings lost,’ and finally ‘screaming with a suffering body and mind, in the darkness.’ Conclusion: The findings of this study provide a deep understanding and insights of the lived experience of suffering from vision loss in adults with acquired visual impairment. Based on the results of the study, health professionals can develop better caring programs to support adults with acquired visual impairment, and their family.
