Document Summary
The dark adaptation technique, where they measure the dark adaptation curve Dark adaptation occurs following extended exposure to the dark. Three separate types of experiments have been used. Test light might be presented in the fovea r the periphery. Results show a dark adaptation curve: periphery. periphery contains primarily rods, but contains some cones. Sensitivity to the test light - looks as though there are two parts of this function, Reason: we are measuring both the responses of the rods and cones. what is. High sensitivity is represented by lower values. and it appears there are needed is that we need a measurement of the rods and cones separately. Fovea only has cones, so if you repeat the experiment at the fovea, then you will have the results of only the cone. Place light at fovea so test light only stimulates cones. Results show that sensitivity increases for three to four minutes and then levels off.
