LogMAR visual acuity, contrast sensitivity and glare sensitivity measurements were made on
39 eyes of 18 cataractous subjects and compared against normative data. Only cataracts of …

Background. Several epidemiological investigations show a correlation between cataract
development and the dose of ultraviolet radiation (UVR) received. It is experimentally well …

Theoretical calculations were performed to assess the relative contribution to turbidity of
changes in the refractive index as compared to changes in the aggregate size. It was found …

Background Yellow filters are sometimes recommended to people with low vision. Our aim
was investigate the effects of three commercial yellow filters on visual acuity and contrast …

purpose. To investigate the relationships between visual acuity, contrast sensitivity, and 11
clinicopathologic classes of opacity in the human crystalline lens. methods. The Somerset …

Glare disability plays an important part in the investigation and assessment of cataract. We
investigated the effect of monocular glare disability on binocular contrast sensitivity. The …

Purpose: Unclear ocular media is a very common condition of older eyes characterized by
significant light scattering and image degradation. The multifocal electroretinography …

In most types of senile cataracts the physical basis for opacification is increased light
scattering. The scattering is caused by variations in refractive index within the lens. Local …

A symposium on comparative aspects of lens and red blood cell biochemistry was he] d at
