Comparison of ophthalmological standards applicable to drivers in Poland and the United Kingdom with the European Union recommendations

open access: yesJournal of Ophthalmology, 2022
Each country has its own specific requirements with regard to the visual standards applicable to drivers. The following were summarised in the appropriate tables: 1) data contained in the Ordinance of the Minister of Health from the 30th of August 2019 ...

Vision through Healthy Aging Eyes

open access: yesVision, 2021
As life expectancy grows, so too will the number of people adversely affected by age. Although it is acknowledged that many conditions and diseases are associated with age, this mini-review will present a current update of the various visual changes that

Modeling Reactive Oxygen Species-Induced Axonal Loss in Leber Hereditary Optic Neuropathy

open access: yesBiomolecules, 2022
Leber hereditary optic neuropathy (LHON) is a rare syndrome that results in vision loss. A necessary but not sufficient condition for its onset is the existence of known mitochondrial DNA mutations that affect complex I biomolecular structure.

Lightness constancy: ratio invariance and luminance profile [PDF]

open access: yes, 2009
The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields.

Gaze-contingent flicker pupil perimetry detects scotomas in patients with cerebral visual impairments or glaucoma [PDF]

open access: yes, 2018
The pupillary light reflex is weaker for stimuli presented inside as compared to outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of impaired visual processing.

Attention modulates spatial priority maps in the human occipital, parietal and frontal cortices. [PDF]

open access: yes, 2013
Computational theories propose that attention modulates the topographical landscape of spatial 'priority' maps in regions of the visual cortex so that the location of an important object is associated with higher activation levels.

The Computational Magic of the Ventral Stream: Towards a Theory [PDF]

open access: yes, 2011
I conjecture that the sample complexity of object recognition is mostly due to geometric image transformations and that a main goal of the ventral stream – V1, V2, V4 and IT – is to learn-and-discount image transformations.
