Different regional changes of fluorescence spectra of clear human lenses and nuclear cataracts Fluorescence spectra are recorded from the cortex and nucleus of the same human lenses [clear and cataracta brunescens (nigra) with colorless cortex]. When... H Pau,DHH Schmidtke - 《Graefes Archive fo...
There are several factors to consider when deciding what type of sunglasses you should wear. Choosing a frame to suit your face shape or choosing suitable lenses for certain activities are things to consider. Some frames suit some face shapes more than others, for example, round or oval sunglas...
Material and methods: Human lenses were characterized by slit-lamp investigations as bearing different types of senile cataracts. Subsequently, lenses were removed by intracapsular extraction. Clear human lenses served as controls. Bovine lenses served to standardize freeze-cutting and incubation for ...
The light intensity level had a positive effect on the contrast sensitivity of the examined eyes, except for eyes with cataract simulation, where even the maximum light intensity did not improve the contrast vision. This indicates that patients with cataracts require increased contrast of text rather...
cataracts from prolonged exposure to ionizing radiation. In the past, those who wore corrective lenses would often be required to wear bulkyradiation safety gogglesorfit over lead glasses.

Opticians solely help you with the fit of your glasses and contacts overall.Ophtha...
which is consistent with our findings. Kurodaet al.25described that in nuclear cataracts, the polarity of spherical aberrations is negative because the wavefront is delayed when the ray travels inside the higher refractive index hard nucleus, whereas normal lenses have positive spherical aberrations. ...

The purpose of this study was to investigate the different expressions of αA-crystallin and αB-crystallin in human lens epithelium of age-related and congenital cataracts. The central part of the human anterior lens capsule approximately 5 mm in d
while in one case-control study six of the 68 glaucoma cases also had cataracts [11]. The majority of case-control studies controlled for age when analysing their main results, by matching groups by age and/or by adjusting for the influence of age. However, in two studies with significant...
