WebJan 23, 2024 · The retina is the innermost layer of the eye. It consists of photoreceptor cells (e.g. rods and cones) that convert light energy into a nerve impulse. This impulse is passed through the optic nerve to the visual cortex allowing us to visualise our surroundings. In this article, we will discuss the layers of the retina, the function of the photoreceptor, … WebDark Adaptometry (DA) Dark adaptometry (DA) measures the eye’s ability to detect a dim light, a measure of rod photoreceptor function. Two values are measured: the dimmest light the eye can detect the dark adaptation …
