Although it was not possible to determine exactly whether the retinal area used by the participants in the present study was the preferred retinal locus or a newly established trained retinal locus, it appears that this method of training eccentric viewing to a particular retinal area improves both near acuity and the performance of activities of daily living, regardless of whether the participants had an established preferred retinal locus.
