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.

完整的视觉功能对于儿童发挥其学习潜能是必不可少的。在没有视力筛查的情况下，儿童可能会注意到未被注意的视力障碍，学业上的挑战可能归因于其他问题，例如学习或认知障碍。如果视觉问题得不到承认，则会对教育成绩产生不利影响。随着教育和经济的发展停滞不前，这不仅给孩子带来了终生后果，也给整个社会带来了生命。很少有老师知道视觉如何影响阅读和学习。坦桑尼亚的教师参加了CPD课程，以学习视力感觉素质和眼部运动功能，并接受了视力测试方面的培训。基于视觉品质理论和课堂上的观看条件，教师进行了视觉功能评估。n  = 104）用标准化方法进行了测试。数据表明，不同的感觉和眼动技能之间存在明显的联系，并且一个视觉区域中的问题会影响其他视觉区域。近50％的学生的一种或多种视觉功能受到了干扰。另外，光照条件也具有挑战性。当教师了解视力质量及其对阅读和学习的影响时，他们就会理解为什么有些学生会出现阅读问题，动机降低，自尊心受到干扰以及注意力不集中的问题。有了这些见识，就可以帮助更多的学生发挥潜能。
