Use of Single-Vision Distance Spectacles Improves Landing Control during Step Descent in Well-Adapted Multifocal Lens-Wearers
Our previous work (Johnson et al., 2008 J Am Geriatr Soc; 56: 178-180 and 2007 Invest Ophthalmol Vis Sci, 48: 1466-71) has shown that wearing multifocal spectacles can reduce safety on steps and stairs. This study showed that switching to using single-vision distance spectacles improved stairs safety. Collectively our work indicates that use of single-vision distance lenses for everyday locomotion may be advantageous for elderly individuals particularly those who have a high risk of falling. Based on this work we are currently assessing (support from lens manufacturer; Essilor International) the efficacy of using intermediate multifocal lenses for everyday locomotion
