Coloured overlays can reduce symptoms of visual stress and improve reading speed. These benefits are reliable and are not attributable simply to placebo effects. Five percent of children in mainstream education read at least 25% more quickly with an overlay, provided they have chosen the colour. The suboptimal design of children's text and the high level of classroom lighting may be partly responsible.
彩色滤光片可以减轻视觉压力症状并提高阅读速度。这些益处是可靠的，并非仅仅归因于安慰剂效应。在主流教育中，5%的儿童使用滤光片阅读速度至少提高25%，前提是他们选择了合适的颜色。儿童课本设计欠佳以及教室照明水平过高可能是部分原因。
