ERG lens with built-in Ganzfeld light source for stimulation and adaptation

A C Kooijman et al. Invest Ophthalmol Vis Sci. 1980 Mar.

Abstract

A contact lens for routine electroretinography which contains a Ganzfeld light source is described. The light source consists of six light-emitting diodes and serves both as a stimulus source and a background illumination. The response characteristics with this source are comparable with those of an integrating sphere stimulator.
