Therefore, the goal of this study is to determine factors that may account for variability in the visual functioning of individuals with a range of refractive errors and their ability to perform everyday activities when equipped with different types of lenses. We hypothesize that the subjects will perform visual tasks of function better when using iZon™ Wavefront-Guided Glasses than with conventional glasses. This hypothesis is based upon the glasses yielding better visual acuity and because the design of the glasses reduces the effects of glare. This research is important so that alternate treatments and vision correction may be implemented which will have a more beneficial impact on those with refractive errors and visual impairment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '35 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Have normal vision\n* Are far-sighted or near-sighted\n* Have no eye diseases Subjects aged 18 and over, who have refractive errors ranging from +5.0 to -5.0 and/or who have eye disease will be included in the study.'}, 'identificationModule': {'nctId': 'NCT00894192', 'briefTitle': 'Comprehensive Evaluation of Visual Function', 'organization': {'class': 'OTHER', 'fullName': 'The Chicago Lighthouse'}, 'officialTitle': 'Comprehensive Evaluation of Visual Function', 'orgStudyIdInfo': {'id': 'OPH-2005-0516'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Wavefront guided lenses', 'interventionNames': ['Device: Izon Wavefront-guided lenses']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Conventional lenses', 'interventionNames': ['Device: Conventional lenses']}], 'interventions': [{'name': 'Izon Wavefront-guided lenses', 'type': 'DEVICE', 'description': 'Subjects will use prescribed eyeglasses for one week.
