Intact visual functions are necessary for children to reach their academic potential. In the absence of vision
screening, children may have unnoticed vision disturbances and academic challenges may be attributed to
other problems, such as learning or cognitive disabilities. Visual problems are detrimental to educational
achievement if they are not recognised. This has lifelong consequences for the individual child but also for
the wider society as educational and economic advances are stifled. Few teachers are aware how vision
influences reading and learning. Tanzanian teachers went through a CPD-course to learn about vision
sensory qualities and ocular motor functions and were trained in vision testing. Building on theory of vision
qualities and viewing conditions in class, the teachers practised vision functions assessment. Under the
supervision of vision scientists, pupils in standard 5 (n=104) were tested with standardised methods. The
data shows that there is a clear connection between the different sensory and ocular motor skills and that
problems in one vision area influence other vision areas. Nearly 50% of the pupils had disturbances in one
or more of the vision functions tested. In addition, the light conditions were challenging. When teachers
learn about vision qualities and their impact on reading and learning, they understand why some pupils have
reading problems, reduced motivation, disturbed self-esteem and problems with concentration. With these
insights, more pupils can be helped to reach their potential.
