Document Summary
Wavelength is to colour as number of photons is to intensity or brightness. Purity of the light is to saturation. Nanometers= 10 to the power of -9. How you see the flowers vs. how a bee sees a flower. Sensitivity is to light as acuity is to details the more sensitive we are the more better we able to pick up light. Lens - allows an image to be focused on the retina. Primitive animals do not have lens of eyes. Sclera - the outer covering of the eyeball, white and opaque, tough 1 mm in. Covers most of the eye except the front. Cornea - translucent membrane at the front of the eyeball. Damage, harder to see (gets milkier) = cornea transplant. More light = constrict allows less light to come in. Sphincter and dilator are smooth muscles that constrict or dilate the pupil.
