Abstract

Purpose: To evaluate the effectiveness of NVDA (Non-Visual Desktop Access) screen reading software to improves daily life task and enhance independence.
Material and Methods: A quasi-experimental study was conducted at LRBT Hospital, Lahore which took 4 months (March to June). 34 participants between the ages 18 to 50 are taken through purposive sampling who are visually impaired and never had used any assistive technology. Participants are guided about the NVDA software and then installed it on their PCs or tablets according to their need. A systematic questionnaire according to WHO guidelines was used to gather data. SPSS version 25.0 was used to analyze the responses, and the findings were presented as percentages and frequencies.
Results: Among the 34 people who participated, 23.5% were women and 76.5% were men. 67.6% of those who responded agreed or strongly agreed that NVDA enhanced their capacity to carry out everyday duties on their own. Furthermore, 64.7% of respondents said that the visually impaired population might greatly benefit from inexpensive assistive technology. The Achieved Functioning domain had the highest mean score (3.87), suggesting a favorable influence on self-assurance and independence regarding technology use.
Conclusion: By allowing digital access, increasing independence in performing everyday tasks, and encouraging social participation, NVDA software considerably improved the standards of life for people with impaired vision. It is a useful assistive device for low vision rehabilitation because of its inexpensive cost, verbal assistance, and simplicity of use.
