Contrast sensitivity testing can be performed quickly, is less demanding than visual field perimetry and can be easily incorporated into a busy clinical practice, according to researchers in the ...

The objective is to determine the characteristics of contrast sensitivity of the human vision system (HVS) by experimental measurements employing a CRT. Said characteristics form the basis for the ...

Monocular contrast sensitivity and microperimetry are useful indicators of visual function and its impact on activities of daily living in those with AMD. Patients with AMD do not rely on binocular ...

Patients who underwent refractive lens exchange with a diffractive multifocal IOL had contrast sensitivity comparable with that of preoperative levels under photopic and mesopic lighting conditions.

Researchers also found correlations between contrast sensitivity function and age, HbA1c, and type 1 diabetes (T1D) duration under different lighting conditions. Individuals with type 1 diabetes (T1D) ...

Researchers previously believed contrast sensitivity function -- the minimum level of black and white that a person needs to detect a pattern -- was mainly dictated by the optics of the eye and ...

It is often difficult for a driver to see a person walking on the side of the road at night--especially if the person is wearing dark colors. One of the factors causing this difficulty is a decrease ...

Deprivation of vision during critical periods of childhood development has long been thought to result in irreversible vision loss. Now, researchers have challenged that theory by studying a unique ...

The contrast sensitivity of persons with different visual acuity capabilities is experimentally analyzed. Test subjects observe a cathode ray tube monitor in a darkroom environment to determine their ...
