Vision
100
This part of the eye constricts or dilates depending on light stimuli
What is the pupil
100
Three fields that involve optics, or involve the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it, are:
What are (in no particular order, and I will accept others with justification): astronomy, various engineering fields, photography, and medicine (particularly ophthalmology and optometry).
100
These three colors are considered "secondary" on a pigment-mixing color wheel.
What are orange, green, and purple
100
This trait of human vision is the reason we appeared to have a hole in our hand when looking through an old paper roll.
What is binocular vision
100
This anatomical part transmits visual information from the retina to the brain
What is the optic nerve
200
This type of cell is a human's color receptor cell
What is a cone cell
200
This is an optical and meteorological phenomenon that is caused by both reflection and refraction of light in water droplets resulting in a spectrum of light appearing in the sky.
What is a rainbow
200
These two colors are the most frequent colors that people with colorblindness omit or are not able to perceive
What are red and green
200
The visual ability to perceive the world in three dimensions (3D) and the distance of an object, or this property of vision, is aided by binocular vision.
What is depth perception
200
This is the ability to mentally combine images from both eyes into a single image
What is binocular vision
300
This is the outer layer of the eye where light is initially refracted.
What is the cornea
300
This type of lens causes parallel light rays to diverge, or spread out.
What is a concave lens
300
This is the result of additive color mixing when all three colors are mixed centrally.
What is white/white light
300
This model is constructed so that from the front it appears to be an ordinary cubic-shaped room. However, the true shape of the room is trapezoidal, resulting in a trick of scale and perspective.
What is the Ames room model
300
This process is responsible for image formation by lenses and the eye.
What is refraction
400
This part of the eye contains rods and cones and imprints visual information
What is the retina
400
This property is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image, frequently utilized in film and photography
What is depth of field
400
These three colors, in order, are the complementary colors to red, blue, and yellow on a simple pigment color wheel.
What are green, orange, and purple.
400
This optical illusion uses binocular vision to create the illusion of three dimensions, as exhibited in the Magic Eye book series.
What is a stereogram/stereography
400
This condition means an uneven or lumpy cornea, and it causes blurry vision.
What is astigmatism
500
This is the clear gel that fills the space between the lens and the retina of the eyeball of humans and other vertebrates.
What is the vitreous humor
500
This is an object that reflects light in a way that preserves much of its original quality subsequent to its contact with said object
What is a mirror
500
This word is what the "K" stands for on a CMYK subtractive color model.
What is "key" (I will accept "black" for 250 points)
500
This type of illusion, as seen in MC Escher's Waterfall, is assumed to arise by interaction with assumptions about the world, leading to "unconscious inferences", an idea first suggested in the 19th century by the German physicist and physician Hermann Helmholtz.
What is cognitive illusion
500
Hyperopia, commonly known as this condition, means that the lens focuses the image past the retina, causing difficulty focusing on close-range objects
What is farsighted/farsightedness
