The effect of viewing distance on responses to the pattern glare test [PDF]
Australasian journal of optometry, The, 2016 We investigated whether symptoms of pattern glare were affected by viewing distance, as distinct from spatial frequency, because of an association between symptoms and anomalies of accommodation and vergence.One hundred young adults viewed gratings with spatial frequencies of 0.3, 2.3 and 9.4 cycles per degree (cpd) at four test distances (0.4, 0.8, 1 ...

The Pattern Glare Test: a review and determination of normative values [PDF]
Ophthalmic and Physiological Optics, 2008 Abstract Pattern glare is characterised by symptoms of visual perceptual distortions and visual stress on viewing striped patterns. People with migraine or Meares–Irlen syndrome (visual stress) are especially prone to pattern glare. The literature on pattern glare is reviewed, and the goal of this study was to develop clinical norms ...

Study of Anti-Glare Pattern Forming Process by Glass Etching for Improved Image Quality
Journal of Nanoscience and Nanotechnology, 2021In this paper, the anti-glare characteristics of strengthened glass used in the dashboard of automobiles were improved to enhanced the ability of the driver to read the display. To this end, the glass surface was etched with a solution containing HF as a main component.

Photo‐Rewritable Glaring Patterns Composed of Stripe Domains in Nematic Elastomers
Macromolecular Rapid Communications, 2022AbstractDynamic ordered micropatterns in polymeric materials provide an effective approach for the on‐demand tuning of optical properties toward a smart optical material. In this study, it is shown that glaring patterns exhibiting strong anisotropic light diffusion can be developed at specific locations in nematic liquid‐crystal elastomers with light ...

Identifying Patterns of Key Factors in Sun Glare-Related Traffic Crashes
Transportation Research Record: Journal of the Transportation Research Board, 2021Sun glare is one of the major environmental issues contributing to traffic crashes. Every year, many traffic crashes in the United States are attributed to sun glare. However, quantitative analysis of the influence of sun glare on traffic crashes has not been widely undertaken.

Glare: A free and open-source software for generation and assessment of digital speckle pattern
Optics and Lasers in Engineering, 2022Abstract Generating digital speckle image and its corresponding deformed image is the basis of digital image correlation research. At present, however, it still lacks a powerful, easy-to-use, and user-friendly professional software concerning generation and assessment of digital speckle pattern.

Assessing and Modeling Discomfort Glare for Raw White LEDs with Different Patterns
LEUKOS, 2016ABSTRACTThis article describes an experiment carried out to evaluate discomfort glare of nonuniformly distributed light emitting diode (LED) sources. The glare sources were created with a 4 × 4 LED panel. Twenty participants evaluated 140 lighting conditions consisting of eight nonuniformity patterns, four to five levels of luminous intensity, two ...

Scotopic sensitivity syndrome or the Irlen syndrome describes symptoms of asthenopia anamolous visual performance experienced while reading that are lessened by colored filters. One putative explantation for this condition relates to pattern glare: a hypersensitivity to repetitive patterns, including lines of print on a page.

Pattern VEP for glare sensitivity testing.
Australasian physical & engineering sciences in medicine, 2000Conditions such as optic neuritis and cataract cause a patient to be unduely affected by glare and this occurs even though they may have normal visual acuity. A new test incorporating visual evoked potential (VEP) and glare sensitivity has been developed in Christchurch which shows promise for the objective assessment of such conditions.
