'Ease of adaptation' predicts preferred spectacle prescriptions better than visual acuity: a retrospective analysis.

Clinical Relevance: Factors predicting patient acceptance of a new spectacle prescription need to be determined to make optimal prescribing decisions.

Background: Clinicians usually prescribe for best visual acuity. However, for some patients, a partial change is prescribed to ease adaptation, despite providing suboptimal visual acuity.

Distance spectacle-wearing habits in older patients in England.

Purpose: To report the proportion of older people in England who wear distance spectacles full time, part time and rarely, and to investigate factors that influence how much the distance vision (DV) correction is worn.

Methods: A two-part questionnaire investigating the spectacle-wearing habits of older people was developed and completed by 322 participants (age 72 years ±7.7, range 60-94).

The Visual Impact of Lens-Induced Astigmatism is Linked to Habitual Axis.

Purpose: Many studies have assessed the visual impact of astigmatism by inducing it using loose trial lenses at set axes. There are conflicting opinions and some confusion about the results, but the reduction in vision is typically least with lens-induced with-the-rule astigmatism. In this study, we determined whether a participant's habitual astigmatism influences the impact of lens-induced astigmatism on distance visual acuity (VA).
