After three months (at least) they should came back to center and fill the second form. The first form was about functional vision without LVA and second too, but by using of LVA. They have been compared to fulfill the result of research. Data were analyzed by Spearman correlation coefficient, Chi – square and Wilcoxon tests.

Results: Spearman correlation coefficient between use of LVAs for near with duration and frequency of study were 0/491 and 0/520 with probability values such as P=0/003 and P=0/002 that shown significant relation. There was significant difference in traffic measure and environment knowing between before and after of far LVAs using (P=0/002) and their SCC was 0/499. There was significant relation between use of low vision aid and education after prescription (P=0/011).
