Adaptometer
Definition
A laboratory apparatus used in ophthalmology and physiology to measure the speed and capacity of the eye to adapt to darkness or sudden variations in light intensity. The device projects precisely controlled light stimuli, enabling the determination of the retinal adaptation curve and the diagnosis of night blindness or other photoreceptor cell dysfunctions.
