Visual correlates of specific learning difficulties (SpLD) include: binocular instability, low amplitude of accommodation, and Meares-Irlen Syndrome. Meares-Irlen Syndrome describes asthenopia and perceptual distortions which are alleviated by using individually prescribed coloured filters. Data from 323 consecutive patients seen over a 15 month period in an optometric clinic specialising in SpLD are reviewed. Visual symptoms and headaches were common. 48% of patients were given a conventional optometric intervention (spectacles, orthoptic exercises) and 50% were issued with coloured filters, usually for a trial period. 40% of those who were given orthoptic exercises were later issued with coloured overlays. 32% of those who were issued with coloured overlays were ultimately prescribed Precision Tinted lenses. Approximately half the sample were telephoned more than a year after the last clinical appointment. More than 70% of those who were prescribed Precision Tints were still wearing them daily, and results for this intervention compared favourably with data for non-tinted spectacles. The data suggest that many people with SpLD need optometric care and that the optometrist needs to be skilled in orthoptic techniques and cognisant of recent research on coloured filters.
特定学习困难（SpLD）的视觉相关因素包括：双眼不稳定、低调节幅度以及米尔斯-厄伦综合征。米尔斯-厄伦综合征描述的是视疲劳和感知扭曲，使用个体定制的彩色滤光片可缓解这些症状。本文回顾了一家专门治疗SpLD的验光诊所15个月内连续接诊的323例患者的数据。视觉症状和头痛很常见。48%的患者接受了传统的验光干预（配镜、视光训练），50%的患者佩戴了彩色滤光片，通常是试用一段时间。接受视光训练的患者中有40%后来佩戴了彩色覆盖物。佩戴彩色覆盖物的患者中有32%最终配了精准染色镜片。大约一半的样本在最后一次临床就诊一年多后接受了电话随访。超过70%配了精准染色镜片（Precision Tints）的患者仍每天佩戴，与未染色眼镜的数据相比，这种干预的效果良好。数据表明，许多SpLD患者需要验光护理，验光师需要熟练掌握视光技术，并了解彩色滤光片的最新研究情况。
