An increasing number of non-optometric sources are selling standard glasses (with a range of lens powers available) for reading and other near-work tasks. Collectively these tend to be referred to as ‘ready readers’.
Project conclusions
- just over half of all ready-made spectacles used in the study provided the optical standards required of them by the relevant British and European Standard
- higher-powered ready-made spectacles were more likely to have errors (+3.50DS)
- the quality of these ready-made spectacles could be easily improved by the use of more appropriate inter-pupillary distances for the work they are intended for.
