Eye anatomy components?
Cornea, iris, pupil, lens, retina, optic nerve.
Cornea — function?
Refracts incoming light to focus on retina.
Photoreceptors types?
Rods for low light, cones for color.
Iris — role?
Controls pupil size, regulates light entry.
Visual pathway steps?
Retina, optic nerve, chiasm, cortex.
Pupil — function?
Adjusts size to regulate retinal light exposure.
Lens — role?
Fine-tunes focus via accommodation.
Retina — contains?
Photoreceptors: rods and cones.
Optic nerve — function?
Transmits visual signals to the brain.
Rods vs cones — difference?
Rods: night vision; cones: color and sharpness.
