As the organism ages, all organs, including those related to vision, change. Thus, even with healthy aging, certain aspects of a person's visual functioning decline. The aim of this study was to determine whether there is a decrease in binocular vision, especially stereo vision, in the elderly, and if it has any effect on the daily activities and mobility of subjects. In addition, the aim was to see whether there are differences in stereoscopic vision and difficulties in these areas between people living in their own households and people living in a retirement home. From the set goals, we wanted to gain insight into the problems at the daily life and mobility of the elderly, associated with an impaired binocular vision, to detect areas in need of support and adaptation, with the aim of improved visual functioning. 40 respondents aged 65 and over were tested of whom 20 are beneficiaries of the Sveta Ana Retirement Home and 20 are living independently. For the purposes of the research, we constructed a Questionnaire on the visual behavior and a Questionnaire to assess the impact of binocular vision on everyday activities and mobility of the Likert type. We also constructed 2 protocols in which we recorded the results of the two assessments. First of the sensory and motor components of binocular vision and second for the quality of performance on the tasks influenced by stereo vision. The results showed a weakening of the stereo vision and a high prevalence of stereo blindness as well as the influence of the mentioned on the frequency in which subjects have mobility difficulties in indoor and outdoor space and in moving on the stairs. People in a retirement home have also been shown to have a statistically significant reduced stereo vision compared to people living in their own household. We believe that this research will contribute to the creation of better access to vision-related services in the population of the elderly and enable the creation and implementation of adaptations for their improved visual functioning, with the aim of improving the quality of life.
