The influence of spectral power distribution on contrast sensitivity
(SAGE Publications, 2011-07)
The influence of lighting of different spectral power distribution on letter contrast sensitivity has been studied. The different spectral power distributions were obtained by filtering or dimming tungsten halogen lamps. ...
Light adaptation in letter contrast sensitivity: The influence of optical and neural mechanisms
(Sage Publications, 2013-06)
This work discusses the level of implication of the optical and physiological mechanisms in letter contrast sensitivity (CS) under different conditions of environmental lighting. A study was carried out on 26 eyes with ...
Quantitative and functional influence of surround luminance on the letter contrast sensitivity function
(Wiley Blackwell Publishing, Inc, 2010-03)
Aim: To determine the influence of surround luminance on the letter contrast sensitivity function. Method: The binocular contrast sensitivities of 31 young and ocularly healthy individuals were measured with letters of ...
Parafoveal letter recognition at reduced contrast in normal aging and in patients with risk factors for AMD
(SPRINGER, 2009)
Background Patients with early age-related maculopathy ( ARM) do not necessarily show obvious morphological signs or functional impairment. Many have good visual acuity, yet complain of decreased visual performance. The ...
Aspect sensitivity considerations in determining day‐to‐night variations in meteor trail durations
(American Geophysical Union, 2009-11-24)
Recently there has been an interest in the day‐to‐night variations in the duration of non‐specular meteor trails or Range Spread Trail Echoes (RSTE). The reported differences between the day and night durations of meteor ...
Imaging with an extended depth of field by means of the peacock eye optical element

Effect of+3.00 diopter and+4.00 diopter additions in multifocal intraocular lenses on defocus profiles, patient satisfaction, and contrast sensitivity
(ELSEVIER SCIENCE INC, 2011)
PURPOSE: To evaluate the advantages and disadvantages of the new low-addition (add) (+3.00 diopter [D]) ReSTOR multifocal IOL compared with the preceding ReSTOR model with +4.00 D add. SETTING: University Eye Hospital, ...
Sensitivity variations of Listeria strains to the bacteriocins, lactocin 705, enterocin CRL35 and nisin
(Springer, 2001-12)
Five strains of Listeria monocytogenes, four strains of Listeria innocua and a strain of Listeria seeligeri showed different sensitivities to lactocin 705 (17 000 AU ml-1), enterocin CRL35 (8500 AU m1-1) and nisin (2500 ...
