𝐅𝐚𝐬𝐜𝐢𝐧𝐚𝐭𝐢𝐧𝐠 𝐅𝐚𝐜𝐭𝐬 𝐀𝐛𝐨𝐮𝐭 𝐄𝐲𝐞 𝐀𝐧𝐚𝐭𝐨𝐦𝐲 𝐚𝐧𝐝 𝐕𝐢𝐬𝐢𝐨𝐧! Refractive power of the eye: About 60 diopters (cornea about 40 diopters, lens: about 20 diopters) On the retina of an eye there are more than 100 million sensory cells sending the image information to the brain (a camera has probably 10 million pixels). The retina contains two types of photoreceptors, rods and cones. The rods are with some 120 million more numerous. They are responsible for seeing at night. The 6 to 7 million cones provide the eye‘s colour sensitivity for seeing at daylight. They are concentrated in the 0.3 mm diameter fovea. The eye can be very strong: In a dark night, you can see the light of a candle in up to 25 km distance! #EyeAnatomy #VisionScience #Optometry #EyeHealth #RefractivePower #SensoryCells #Photoreceptors #VisionCare #Healthcare #LightAndVision #OpticalScience #GEMOPTICIANS
