The objective of this study was to investigate the psychological adaptation process to traumatic blindness through a qualitative approach based on grounded theory. The study population was composed of young adults aged 20 to 40 who resided in Tehran and had experienced a sudden and traumatic loss of vision in 2022. The sample included 12 individuals who had experienced traumatic blindness and were selected through theoretical sampling until data saturation was achieved. Data were collected using in-depth semi-structured interviews. Interviews typically lasted between 90 and 120 minutes. MAXQDA-10 was employed to derive themes at three levels. Coding validity was proven both by another coder (inter-coder agreement) (0.75) and a recoding by the researcher (re-coding the data using a different approach) (0.78). Under 24 themes, there were 443 codes in 91 central categories. The phenomenon of psychological adaptation to traumatic blindness encompassed the following: fear, hesitation, depression, challenge, irritation, and the difficulty of adapting to a new life scenario. In the context of family, relations, and society, gains prior to the trauma, the trauma modality, concomitant events, and personality were casual conditions. Motivation and the behavior of care providers were recognized as interveningfactors. The primary strategies employed in the adaptation process were the following: making, recreation life style, emotional avoidance, enhanced efficacy, bonding with partners, belief system, and pain management. Traumatic blinds either regain consciousness or become despondent and defenseless as a consequence of their adaptation efforts
