Resumen
Reading efficiency is one of the main concerns among the teachers, publishers, and also eye care practitioners. The size of the text was among factor that might affect the reading. The eye movement behaviour was studied in six different text legibility. The saccades and fixation were recorded and tracked among twenty-five university students. Significant changes in eye movements behaviour in term of saccades and fixations occurred when the university students read passages with different text legibility. The eye movements behaviour was able to adapt to the changes in shape, and size of presented reading materials for better understanding of reading.
