Butterfly Optics Exceed the Theoretical Limits of Conventional Apposition Eyes [PDF]
, 1987 Optical experiments on butterfly compound eyes show that they have angular sensitivities narrower than expected from conventional apposition eyes. This superior performance is explained by a theoretical model where the cone stalk is considered as a ...

Intraocular pressure in a cohort of healthy Eastern European schoolchildren: variations in method and corneal thickness [PDF]
, 2012 BACKGROUND: Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Measurements are needed on many cohorts of children with different
