The Low Vision Committee of the EBU is of the opinion that definition must cover a larger number of parameters to better define visual problems: As a first step to better assessment of visual abilities a list of parameters has been worked out which should be taken into account in assessing partial sight. In order to help low vision professionals to get better information from ophthalmologists the low vision committee has designed a new questionnaire wich will be sent out to the national organisations of the EBU for discussion. The need of magnification and the visual acuity are recorded on a thermometer like scale based on logarithmic steps. Most other questions are multiple choice
