#retina test
- Adaptometry — A clinical method of investigation and diagnosis used in ophthalmology to determine the eye's capacity (specifically the retina's) to adapt to variations in light and darkness. This medical procedure measures the absolute light sensitivity threshold of visual receptors over time, allowing the early identification of retinal disorders or hemeralopia (night blindness).
- Adaptometer — 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.
