What Do You Know About Our Eyes? - Quiz

The eye is one of the five sense organs i. E. It is one of those organs that helps us interact with our environment and fellow humans. Try this to see how much you know about this delicate part of our body.


Questions and Answers
  • 1. 

    ______________________ is the liquid substance in the eye.

    • A.

      Retina fluid

    • B.

      Vitreous humor

    • C.

      Aqueous Humor

    • D.

      Optic fluid

    Correct Answer
    C. Aqueous Humor
    Explanation
    The correct answer is Aqueous Humor. Aqueous humor is a clear, watery fluid that fills the front portion of the eye, between the cornea and the lens. It helps maintain the shape of the eye and provides nutrients and oxygen to the surrounding tissues. It also helps to remove waste products and maintain the intraocular pressure, which is important for proper eye function.

    Our eyes reacts to light and _________________.

    • A.

      Speedd

    • B.

      Moist

    • C.

      Pressure

    • D.

      Heat

    Correct Answer
    C. Pressure
    Explanation
    Our eyes react to light and pressure. When light enters our eyes, it stimulates the photoreceptor cells in the retina, which then send signals to the brain to process the visual information. Additionally, our eyes also have a built-in mechanism to detect changes in pressure. This is evident in situations such as when we feel pressure changes during takeoff and landing in an airplane or when we experience changes in altitude. Therefore, pressure is a factor that affects our eyes along with light.

    _________________ is shortness of sight.

    • A.

      Myopia

    • B.

      Astimagtism

    • C.

      Hypopia

    • D.

      Hyperopia

    Correct Answer
    A. Myopia
    Explanation
    Myopia is the correct answer because it refers to shortness of sight, also known as nearsightedness. This condition causes difficulty in seeing objects that are far away, while close objects can be seen clearly. Myopia occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. This results in blurry distance vision.

    _________________ connects the eye to the brain.

    • A.

      Eye pipeline

    • B.

      Retina Lobe

    • C.

      Olfactory Lobe

    • D.

      Optic Nerve

    Correct Answer
    D. Optic Nerve
    Explanation
    The optic nerve connects the eye to the brain. It is responsible for transmitting visual information from the retina to the brain, allowing us to perceive and interpret what we see. Without the optic nerve, the information captured by the retina would not be able to reach the brain, resulting in vision loss.

    The dark circular opening in the eye is called ____________

    • A.

      Conjuctivitis

    • B.

      Cornea

    • C.

      Pupil

    • D.

      Irish

    Correct Answer
    C. Pupil
    Explanation
    The dark circular opening in the eye is called the pupil. It is located in the center of the iris, which is the colored part of the eye. The pupil regulates the amount of light that enters the eye by dilating or constricting in response to the intensity of the light. When there is low light, the pupil dilates to allow more light to enter the eye, and when there is bright light, the pupil constricts to reduce the amount of light entering the eye.

    The dense outer coating of the eyes that forms the white is called ________________

    • A.

      Cornea

    • B.

      Pupil

    • C.

      Sclera

    • D.

      Retina

    Correct Answer
    C. Sclera
    Explanation
    The dense outer coating of the eyes that forms the white is called the sclera. The sclera is a tough, fibrous tissue that covers the entire eyeball except for the cornea. It provides protection and support to the eye, maintaining its shape and structure. The sclera also serves as an attachment point for the muscles that control eye movement.

    A doctor that specializes in the treatment of the eye is called ______________

    • A.

      Gynecologist

    Explanation
    An optician is a healthcare professional who specializes in the treatment and care of the eye. They are trained to prescribe and fit eyeglasses and contact lenses, as well as provide advice on vision correction and eye health. Unlike a gynecologist, dentist, or surgeon, an optician specifically focuses on the eyes and their related conditions and treatments.

    The outermost coat of the pupil is called ______________________

    • A.

      Cornea

    • B.

      Iris

    • C.

      Sclera

    • D.

      Cone cells

    Correct Answer
    A. Cornea
    Explanation
    The outermost coat of the pupil is called the cornea. The cornea is a transparent, dome-shaped structure that covers the front part of the eye. It acts as a protective layer and helps to focus light entering the eye onto the retina. The cornea also plays a crucial role in maintaining the shape of the eye.

    ___________________ controls the flow of light into the eye.

    • A.

      Retina

    • B.

      Pupil

    • C.

      Iris

    • D.

      Lens

    Correct Answer
    A. Retina
    Explanation
    The retina is a layer of tissue located at the back of the eye that contains light-sensitive cells called photoreceptors. These photoreceptors convert light into electrical signals that are then sent to the brain via the optic nerve for processing. Therefore, the retina plays a crucial role in controlling the flow of light into the eye by capturing and processing the incoming light.
