Visual perception of graphemes of students with regard to the degree of visual impairment

Aim of this work was to establish perception of graphemes of different types and sizes of subjects with impaired vision, with the regard of the degree of visual impairment. Sample and Methods Used: This research involved fifty children from the elementary school, from the Center for the blind and visually impaired children and youth in Sarajevo, ages from 6 to 15, with different degrees of visual impairment. We used 10 texts which were appropriate for the different ages of the questioned children. All the texts had 50 words or 476 graphemes. In this research we used graphemes of the Arial type with no spacing, Times New Roman and Arial Black with spacing. We also questioned letter sizes, which were of the following sizes; cicero (12,5 tt - 4,513mm); milt (14,5 tt – 5,265 mm); cicero and a half (18 tt - 6,769 mm); two cicero (24 tt - 7,521mm). Results have shown that the subjects with different visual impairment prefer to read different types and sizes of the graphemes. We also concluded the existence of a significant difference between the subjects with different degree of visual impairment when it comes to choosing the size of graphemes and the type of the letters. This work shows the importance of choosing the type and the size of graphemes in the education of students with the different levels of visual impairment.
