It is concluded that refractive errors, visual acuity, and ocular pathology are not correlates of developmental reading difficulties. However, refractive errors are common and can affect the ability to

For each of these conditions, any associations with reading difficulties are reviewed, including their cause. The treatment of these conditions is discussed, also addressing the general question of when optometric factors need to be trea

,Coloured Filters—Early Studies,filters are the result of techniques for tinting plastic ophthalmic lenses that permit the selection of spectral transmission for coloured glasses on an individual basis. The two new systems developed to use this technology in the 1980s for precision tinted lenses are described, together with associ
