Real-time machine learning object detection algorithms are often found within autonomous vehicle technology and depend on quality datasets. It is essential that these work correctly in everyday conditions as well under strong sun glare. Reports indicate glare one of the two most prominent environment-related reasons for crashes. However, existing datasets, such Laboratory Intelligent & Safe Aut...

PURPOSE To determine the effect of cataract type and severity in eyes with pure types of age-related lens opacities on visual acuity (VA) and contrast sensitivity in the presence and absence of glare conditions. METHODS Sixty patients with senile cataracts aged 40 years or older with no other ocular pathologies were evaluated for VA and contrast sensitivity with and without glare. Lens opacit...

Scatter in a detector and its housing can result in image degradation. Typically, such scatter leads to a low-spatial frequency 'glare' superimposed on the primary signal. We infer the glare-spread function (GSF) of an amorphous-silicon flat-panel detector via an edge-spread technique. We demonstrate that this spread (referred to as 'scatter-glare' herein) causes a low-spatial frequency drop in...

Photovoltaic (PV) systems form an important force in the implementation of renewable energies, but as we all know, the force has always its dark side. Besides efficiency considerations and discussions about architectures of power distribution networks, environmental impacts caused by optical reflections are a serious concern. PV systems generate optical reflections resulting in glare. On the on...

This is an introductory report on some experiments performed to explore the issues involved in using a digital camera to make images that can be used to measure the brightness of commercial light sources. Interest in these measurements is a consequence of our desire to learn more about techniques and methods for defining, measuring, and characterizing glare associated with various light sources...

A biometry-based human eye model was developed by using the empirical anatomic and optical data of ocular parameters. The gradient refractive index of the crystalline lens was modeled by concentric conicoid isoindical surfaces and was adaptive to accommodation and age. The chromatic dispersion of ocular media was described by Cauchy equations. The intraocular scattering model was composed of vo...

PURPOSE To determine the safety and efficacy of the Ophtec model 311 iris reconstruction lens for treatment of visual disturbances, such as glare or photophobia, related to partial or total absence of the human iris. DESIGN Phase I multicenter, nonrandomized, investigational device study. PARTICIPANTS Ten iris reconstruction lenses were placed in 10 subjects at 6 sites. METHODS Iris recon...
