Eyes and Vision Trivia Questions

1. What do you call the colored part of your eye?

From Quiz
What Can You See?

Answer: Iris

The main job of the iris is to control the size of the pupil. It also controls the amount of light that makes it to the retina. The color of the eye is controlled by genetics, with the majority of people on the earth having brown eyes.

2. What is the most common disease affecting the health of the optic nerve?

From Quiz The Eyes Have It

Answer: Glaucoma

The optic nerve is a cable made up of 1 million separate fibers. Glaucoma is a disease that causes damage to the optic nerve with abnormally high intraocular pressures. The most common type of glaucoma is called chronic open angle and is treated most commonly with drops. The second most common type is narrow angle glaucoma and is most commonly treated by laser iridotomy.

3. What part of the eye is affected by cataracts?

From Quiz The Cataract Quiz

Answer: lens

A cataract is a clouding of the lens of the eye. The lens lets light pass through to the retina. If the lens is not clear, the eye cannot focus properly and images appear blurry. If left untreated, cataracts can require exceptionally strong corrective lenses or can lead to blindness. Cataracts are the leading cause of reversible blindness and visual impairment worldwide but the key word here is 'reversible'.

4. Xerophthalmia indicates deficiency of what vitamin?

From Quiz One Minute in Ophthalmology

Answer: Vitamin A

Xerophthalmia is the term reserved to cover all ocular manifestations of vitamin A deficiency. Night blindness is the earliest symptom of xerophthalmia in children. Other manifestations are corneal xerosis and keratomalacia. Vitamin A supplements are to be given as treatment.

5. When you go to an ophthalmologist for an eye exam, you are often asked to look at a chart that has rows of letters in decreasing sizes, with a very large "E" at the top, followed by other letters. What is the name of this chart?

From Quiz The Magic Eye

Answer: Snellen chart

The Snellen chart was developed in 1862 by a Dutch ophthalmologist. The Landolt test has a similar format, but consists only of the letter "C" (or "broken rings") with the open area of the "C" in different positions, for the test subject to read. The Taylor chart and the "Tumbling E" chart also are similar in format, and consist of the letter "E" in various configurations. It was designed to be used with people who cannot recognize letters of the alphabet.

6. All right, we'll begin with types of vision problems. What is the effect of myopia?

From Quiz What's That on Your Eyes?

Answer: You can see things up close, but not far away

Myopia, more commonly known as nearsightedness, affects 30% of all Americans. When this happens, the image of a distant object is focused in front of the retina. Because of this, things far away seem blurry without glasses.

7. Anisocoria means that you have a part of one eye bigger or smaller than the same part in the other. Which part of the eye is this?

From Quiz The Eyes Have It

Answer: Pupil

Anisocoria is a rather common condition, and has no major effect on the performance of the eyes. Symptoms for anisocoria include eye pain, reduced eye movement, headaches and drooping eyelids. As anisocoria doesn't affect eyesight, there is no treatment needed unless it is connected to another more serious disease.

8. Which eye disorder causes an opacity in the lens, which if left uncured, may blind you?

From Quiz The Human Eye

Answer: Cataracts

Yes, these are cataracts. You often hear about old people getting them, but these days, treatment is easy for them. There are also many types of cataract, and the most popular is to simply replace the opaque lens with another.

9. While talking about the human eye, what is the "pupil"?

From Quiz Our Eyes

Answer: A hole of variable size

The pupil is a hole through which light enters the eye. It is located at the centre of the front of the eyeball, and appears black in colour because all the light entering it is absorbed by the tissues inside the eye. The size of the pupil determines the amount of light entering the eye. In conditions where there is bright light, the pupil contracts to prevent the light from damaging the eye, and in the dark it dilates, so that maximum light can be absorbed for best vision. The constriction and dilation of the pupil take some time. If you step out of a well-lit room into the dark, then some time must elapse before you are well-adapted to seeing in the dark. Similarly, if you get up in the middle of the night and turn on the lights, it takes some time for your pupil to contract the required amount.

10. The three concentric layers comprising the globe are known as what?

From Quiz A Journey into the Eye

Answer: Tunics

11. What part of the eye is made up of three parts: the optic, the ciliary, and the iridial?

From Quiz What Can You See?

Answer: Retina

The optic part of the retina is the portion of the eye that receives visual light rays. The ciliary and iridial parts of the retina are layer of supporting epithelial cells over the ciliary body. They are also the posterior surface of the iris.

12. What pigment is found in the iris that determines eye color?

From Quiz The Eyes Have It

Answer: Melanin

Lighter skinned populations have less pigment and therefore are more likely to have blue eyes while darker pigmented populations are more likely to have dark brown irises. It is interesting that the pupils of darker pigmented populations take longer to dilate than those of fair skinned people.

13. The inflammation of the lacrimal gland (that produces tears) is called what?

From Quiz One Minute in Ophthalmology

Answer: Dacryoadenitis

It can be caused by the blockage of the duct between the gland and the nose. It usually presents with a swelling and watering from the eyes. An infection can occur if it remains untreated. Dacryocystorhinostomy is the surgery of choice in chronic cases. In this surgery, incisions are in the side of the nose to allow the flow of tears into the nose.

14. What is the effect of hyperopia?

From Quiz What's That on Your Eyes?

Answer: You can see things far away, but not up close

You probably know hyperopia as farsightedness. It could also be called hypermetropia, and the Brits call it longsightedness. Whatever you call it, it affects 5 to 10% of Americans, and close objects are focused behind the retina, unlike myopia. If you have this, things up close seem blurry without glasses.

15. This serious disease is one that clouds the eye lens. It can be caused by several factors including genetics, eye injury or even other eye diseases. Which disease, which is also the word for powerful waterfalls, am I talking about?

From Quiz The Eyes Have It

Answer: Cataracts

Cataracts can cause serious vision problems, and even lead to blindness. The best way to get rid of it, if it is serious, is cataract surgery. The risk of developing cataracts can be increased by smoking, diabetes, family history and exposure to sunlight. Coloboma is a condition in which normal tissue that should be in or around the eye is missing from birth.

16. And what about the coloured part of the eye? What is that called?

From Quiz I Can See Clearly Now

Answer: Iris

The colour of human eyes is determined genetically, though you may not necessarily have the same colour eyes as your parents! Melanin and lipochrome are the two pigments responsible for eye colour, each controlled by a separate gene.

17. Which part of the retinas projects information from the ipsilateral (same side) visual fields to the contralateral (opposite side) hemisphere of the brain?

From Quiz Me, Myself, and Eye

Answer: Nasal

The nasal portion of the retina is located on the inside part of the retina, while the temporal portion is located on the outside; the rostral part does not exist. And this function it serves is done through the optic nerve; The left and right optic nerves of the eye cross at an area called the optic chiasm.

18. In the nineteenth century Albrecht von Graefe was one of the first men to study glaucoma in detail and devise a treatment. In which country did he work?

From Quiz Glaucoma, The Thief of Sight

Answer: Germany

Born in 1828, von Graefe was well educated, having studied logic, anatomy and philosophy at the University of Berlin qualifying in medicine. He pursued his studies in Paris, London, Vienna and Prague before specialising in ophthalmology. One of his major achievements, and there were many, was the introduction of a treatment for glaucoma, the iridectomy - the removal of part of the iris.

19. The only purpose of the sclera is to:

From Quiz A Journey into the Eye

Answer: Maintain the shape of the globe

Although the sclera comprises 70 percent of the globe, since it is opaque it serves no optical purpose other than to maintain the shape of the globe.

20. The leading cause of visual impairment worldwide is refractive error. What is a refractive error?

From Quiz She Blinded Me with Science

Answer: A condition where light does not focus properly on the retina

A refractive or reflection error simply means that light cannot focus in the eye's retina. This can cause a number of issues including nearsightedness and farsightedness. Nearsightedness occurs when the retina is too curved, causing the light to bounce around too much. Farsightedness is caused when the retina is too flat and the light does not reflect properly.

21. Why did humans keep their eyebrows when they lost most of their other body hair?

From Quiz What Can You See?

Answer: Protection

The eyebrow protects the eye from sweat, rain and small items. The way they are shaped and the direction of the hairs causes moisture to flow sideways around the eye and down the side of the face. They also provide expression and shade to the eyes. They are used for communication, but this came later and was not their primary purpose.

22. What is hordeolum externum commonly called?

From Quiz One Minute in Ophthalmology

Answer: Stye

Stye occurs on the eyelids. It is usually caused by the staphylococcus bacteria. It infects the glands of Zeish and the lash follicle to cause a stye. Recurrent styes are commonly seen in patients with diabetes and chronic blepharitis (inflammation of the eyelids).

23. Imagine that you saw the following people on the street, and all of them were wearing glasses. Which one of them is MOST likely to be wearing bifocals?

From Quiz What's That on Your Eyes?

Answer: A person with both nearsightedness and farsightedness

Bifocals, invented by Ben Franklin in 1784, have a lens for seeing far away on the top and a lens for seeing up close on the bottom. Old people wear them more often than younger ones. About the little kid answer, there are glasses with spring hinges so that little kids won't be able to break them if they bend them too far. A person can be both nearsighted and farsighted if they have astigmatism, in which the cornea is irregularly shaped.

24. There is an eye condition called presbyopia. What is the literal meaning of the word?

From Quiz The Eyes Have It

Answer: Aging eye

Given the literal name of it, you can tell it is an age-related condition. Presbyopia is extremely common; most people develop it at some point of their lives. It makes it more difficult to see very close, which affects your ability to do certain things like reading.

25. What is the correct order of the primary visual pathway in the brain?

From Quiz Me, Myself, and Eye

Answer: Retina, Lateral Geniculate Nucleus (LGN), Striate Cortex (V1)

90% of all visual information in the brain uses this pathway. The LGN and MGN are parts of the thalamus. The LGN is for vision, and the MGN is for hearing. The superior colliculus is part of the secondary visual pathway. The retina, fovea, and cornea are basic anatomical visual structures. Brodmann area 17, the striate cortex (V1), and the calcarine sulcus are the same thing, the primary visual area in the brain. Finally, the arcuate fasciculus is a fiber tract connecting Broca's and Wernickes' area, which are for speech.

26. What is the scientific term for the "white of the eye", the part surrounding the eyeball?

From Quiz Our Eyes

Answer: Sclera

The sclera, which is connective tissue made of fibrin (a protein), is the outer protective covering of the eye. The sclera is thinner and less opaque in children, as a result of which the underlying tissue can be seen, thus giving it a bluish look. As one ages, the sclera usually becomes yellower.

27. What is the cause of the most common type of glaucoma?

From Quiz Glaucoma, The Thief of Sight

Answer: Fluids draining too slowly from the anterior chamber

Called primary open angle glaucoma, the type of glaucoma which most often develops is caused when the channels through which fluids drain become clogged over a period of time. This leads to pressure building up in the eye and, if left untreated, will lead inevitably to blindness. Rarer types of glaucoma are acute angle closure glaucoma, which is a sudden blockage of the drainage channels, secondary glaucoma, which results from other eye conditions and congenital glaucoma, which afflicts children.

28. In accommodation, what changes the shape of the lens?

From Quiz A Journey into the Eye

Answer: Ciliary body

The ciliary body also produces the aqueous humor that fills the front chamber of the eye and helps to refract and filter the light entering it.

29. Visually impaired people may use a cane with which color tip to help them walk?

From Quiz She Blinded Me with Science

Answer: Red

One of the universal symbols of blindness is a long, foldable white cane with a red tip. Visually impaired people will use their cane to search the area around them to look for obstacles in their path. These canes and guide dogs give visually impaired people increased mobility they might not have otherwise.
