The influence of operator position, height and body orientation on eye lens dose in interventional radiology and cardiology: Monte Carlo simulations versus realistic clinical measurements [PDF]
, 2016 Objective:This paper aims to provide some practical recommendations to reduce eye lens dose for work-ers exposed to X-rays in interventional cardiology and radiology and also to propose an eye lens correc-tion factor when lead glasses are used.Methods ...

The Stiles-Crawford Effect in the Eye of the Blowfly, Calliphora erythrocephala [PDF]
, 1985 Stiles-Crawford-like effects (that is, directional sensitivity of the retina) were investigated in the fly’s eye. Intracellular recordings from the visual sense cells were made, and the radiation patterns emerging from the photoreceptors with antidromic ...

Design and Simulation of Compound Eye Lens for Visible Light Communication and Illumination
Advances in Condensed Matter Physics, 2020 We proposed a scheme for designing an optical launch system that can make the light intensity more uniform on the receiving plane via a compound eye lens combined with a sunflower plano-convex lens.

Structural aspects of eye lens polyribosomes [PDF]
Biochemical Journal, 1968 Epithelial cells and the outer cortex from lenses of 1-day-old calves contain polyribosomes occurring in clusters of five to ten monomers. The structure of these clusters is not affected by trypsin treatment up to 10μg./ml. of ribosomal suspension. When the whole lens is used as starting material the polyribosomal preparations are strongly contaminated

Profile and Visual Outcome of Patients having Keratoconus Attending Tertiary Eye Hospital, Nepal
Journal of Nobel Medical CollegeBackground: Keratoconus is a bilateral, asymmetric, chronic, progressive ectasia of the cornea in which patients experience distorted vision that is usually treated with rigid contact lenses when spectacles no longer provide adequate vision.

Report of IRPA task group on the impact of the eye lens dose limits [PDF]
, 2017 In 2012 IRPA established a task group (TG) to identify key issues in the implementation of the revised eye lens dose limit. The TG reported its conclusions in 2013.
