Glare assessment in a daylit workplace from a physiological perspective

Marilyne Andersen, Jan Wienold, Sneha Jain

Designing the buildings that facilitate optimum utilization of daylight is desirable for its many benefits [1], [2] yet challenging due to other intrinsic properties of daylight responsible for over-heating and discomfort glare [3]. Discomfort glare has be ...

Outcome and Complications of Combined Modified Deep Sclerectomy and Trabeculectomy for Surgical Management of Glaucoma: A Pilot Study

André Mermoud, Sylvain Roy

Purpose: To report the outcome and complications of a combined surgical technique of modified deep sclerectomy and trabeculectomy (mDST) for glaucoma. Patients and Methods: Retrospective study of 44 eyes of 43 patients with open and closed angle glaucoma w ...

Full field dependence of primary aberrations in perturbed double-plane symmetric systems with a circular pupil

Toralf Scharf, Alessandro Grosso

This paper deals with the theory of primary aberrations for perturbed double-plane symmetric optical systems consisting of a combination of tilted and decentered surfaces and a circular pupil. First, the analytical expressions describing the full field beh ...

Ophthalmic system and method for clinical device using transcleral illumination with multiple points source

Christophe Moser, Timothé Laforest, Mathieu Künzi

An ophthalmic illumination and imaging system with transscleral / transpalpebral illumination of the eye fundus comprises a light-delivering device with a plurality of emitting areas; each of the emitting areas being configured to be independently controll ...

Contrast measures for predicting perceptual effects of daylight in architectural renderings

Marilyne Andersen, María Lovísa Ámundadóttir, Siobhan Francois Rockcastle

Daylit architecture is perceived as a dynamic luminous composition, yet most existing performance metrics were designed to evaluate natural illumination for its ability to adequately illuminate a two-dimensional task surface and avoid glare-based discomfor ...

Corneal epithelial stem cells and their niche at a glance

Freddy Radtke, Craig Nowell

The corneal epitheliumacts as a protective barrier on the anterior ocular surface and is essential for maintaining transparency of the cornea and thus visual acuity. During both homeostasis and repair, the corneal epithelium is maintained by self-renewing ...

Glare Caused By Contrast Between Task And Immediate Surround: An Evaluation Of Luminance Distribution In The Field Of View

Marilyne Andersen, Jan Wienold, Peter Hansen, Mandana Sarey Khanie

Luminance ratios have historically been used to assess glare. Using data from a previous experiment, this exploratory study investigates the relationship between luminance variations in the field of view (FOV), measured as luminance ratios, and glare sensa ...

Chronic inflammation imposes aberrant cell fate in regenerating epithelia through mechanotransduction

Matthias Lütolf, Freddy Radtke, Georg Fantner, Yann Barrandon, Pascal Damian Odermatt, Craig Nowell, Sylke Höhnel

Chronic inflammation is associated with a variety of pathological conditions in epithelial tissues, including cancer, metaplasia and aberrant wound healing. In relation to this, a significant body of evidence suggests that aberration of epithelial stem and ...

Human perceptions of daylight composition in architecture: a preliminary study to compare quantitative contrast measures with subjective user assessments in HDR renderings

Marilyne Andersen, Siobhan Francois Rockcastle

Humans perceive daylight as a rich and dynamic luminous composition and yet existing performance metrics most often evaluate natural illumination for its ability to adequately illuminate a two-dimensional task surface while avoiding glare-based visual disc ...

Innovative strategy of corneal epithelium regeneration using fabricated soft contact lens containing cavities for stem cells transplantation

Julien Graber

Transplantation of donor cornea is widely performed with a high success rate to treat patients with impaired corneal transparency. However the limited number of donors has led scientists to search for new technologies and treatments, including stem cell th ...

Expanding Eye-Tracking Methods to Explain the Socio-Cognitive Effects of Shared Annotations

Andrea Mazzei

Social technologies are leading to transformations in education, by empowering the way learners connect to each other, by introducing new means for teaching and learning and by reshaping the way knowledge is delivered. Annotating texts is a learning strate ...

Conducting polymer microactuators operating in air

Philippe Renaud, Valérie Devaud

We report for the first time on microsized conducting polymer actuators, which operate in air and in liquids. These actuators are potentially useful for a wide range of applications from biotechnology to microrobots. Furthermore, the actuators are fabricat ...

Oligopotent stem cells are distributed throughout the mammalian ocular surface

Yann Barrandon, Ariane Rochat, Georges Abou Jaoudé

The integrity of the cornea, the most anterior part of the eye, is indispensable for vision. Forty- five million individuals worldwide are bilaterally blind and another 135 million have severely impaired vision in both eyes because of loss of corneal trans ...
