Limits of spherical blur determined with an adaptive optics mirror

Autor: Huanqing Guo, David A. Atchison, Scott Warren Fisher

Publikováno v: Ophthalmic and Physiological Optics. 29:300-311

We extended an earlier study (Vision Research, 45, 1967-1974, 2005) in which we investigated limits at which induced blur of letter targets becomes noticeable, troublesome and objectionable. Here we used a deformable adaptive optics mirror to vary sp

Progress in the spectacle correction of presbyopia. Part 1: Design and development of progressive lenses

Autor: Darryl Meister, Scott Warren Fisher

Publikováno v: Clinical and Experimental Optometry. 91:240-250

Most of the commercial advances in the spectacle correction of presbyopia continue to occur in progressive lens design, which has been the focus of intense research and development over the past 60 years by major spectacle lens manufacturers. While p

Noticeable, troublesome and objectionable limits of blur

Autor: Carol A. Pedersen, David A. Atchison, P. Gareth Ridall, Scott Warren Fisher

Publikováno v: Vision Research. 45(15):1967-1974

We investigated limits at which induced blur becomes noticeable, troublesome and objectionable. We used 15 cyclopleged subjects, a Badal optometer with lines of three high contrast letters as targets, 3–6 mm artificial pupils, and 0.0–0.7 logMAR

Relationship between Contour Plots and the Limits of ???Clear and Comfortable??? Vision in the Near Zone of Progressive Addition Lenses

Autor: Scott Warren Fisher

Publikováno v: Optometry and Vision Science. 74:527-531

Purpose. The aim of the study was to determine the relationship between the magnitude of surface astigmatism and subjective estimates of unacceptable blur flanking the near zone of progressive addition lenses (PALs). Methods. Eleven presbyopic subjec

Vertical lens placement as a determinant of acceptance for access near vision lenses

Autor: Michy Kris, Scott Warren Fisher, Andrew C. Griffiths, Saulius Raymond Varnas

Publikováno v: Clinical and Experimental Optometry. 79:205-208

Data were extracted from a recent trial of SOLA ACCESSSTM lenses to examine the effect of vertical lens placement on lens acceptance. In that trial patients wore identical frames with either single vision or ACCESS lenses during a two-week trial peri

Blur limits for defocus, astigmatism and trefoil

Autor: Scott Warren Fisher, David A. Atchison, William N. Charman, Huanqing Guo

Publikováno v: Vision research. 49(19)

We investigated the limits at which blur due to defocus, crossed-cylinder astigmatism, and trefoil became noticeable, troublesome or objectionable. Black letter targets (0.1, 0.35 and 0.6 logMAR) were presented on white backgrounds. Subjects were cyc

Visual Ergonomics, Blur Tolerance and Progressive Lens Design

Autor: Angela Nolan, Scott Warren Fisher, David R. Pope

Publikováno v: Vision Science and its Applications.

Ergonomic data was gathered for subjects reading in a "natural" position. Estimates of eye declination, reading distance and horizontal eye movement were found. Objective and subjective thresholds for blur were also investigated.
