Having just read the minutes of the medical sub-sectorial team on the U.K's CAA SRG website, it seems that the opthalmology working group is to be reformed which will include the re-assesing of the refraction limits. Hopefully the other members of the JAA besides the U.K CAA will see sense and drop the dioptre limit requirement and come into line with standard accepted by the FAA and ICAO.
