    • 2.5D Tactile Graphic
    Diagram of a human eye viewed as a cross-section showing the internal structure. The external side of the eye includes the cornea covering the iris and the pupil letting light in which hits the lens. The central mass of the eye is called the vitreous humor, where the internal side of the eye includes the retina, sclera, and macula point. The whole structure is connected to the optic nerve.

  • The Eye

    • Video
    Closeup of the human eye with lines demonstrating how lights is refracted when it hits the lens. Caption: It behaves like a convex lens, bending or refracting light rays

    The eye is one of each human's major sense organs. It gathers light information and transforms it into a signal that is used by the brain to formulate an appropriate response. How does this process work? What are the structures involved, and what do they do? These questions are answered using a unique, integrated approach that combines the anatomy and function of the eye. Includes detailed footage of the dissection of the bovine eye.

  • Children wearing dark sunglasses against a backdrop of the beach. Spanish captions.

    Explores how eyes work and how eyes help us understand the world. Explains how safe behaviors and healthy habits can prevent illness and injury to eyes. Discusses what to expect from an eye examination and other eye tests. Talks about how visually impaired children walk with a white cane and read Braille.

  • Sixteen eyeballs, each with different eye color. Caption: Martin-Schultz scale.

    How does eye color work? Get ready for a long look deep into the genetics and physics of eye color. Part of the "It's Okay to Be Smart" series.

  • Closeup of the human eye. Caption: tell us how near or far something is.

    This program is devoted to the senses that bring information of more distant events. The camera shows a reckless driver careening down a road—and then takes the viewer inside his eye, where the image of the potential crash site is pictured. The camera enters the ear, showing how the linked bones vibrate in response to a sound, and by using a computer graphic sequence, shows how the eye focuses on an image.

  • Computer screen showing a bar graph and pie chart of energy consumption in watt-hours. Caption: showing me which devices are consuming the most energy.

    Carnegie Mellon University Computer Scientist and Electrical Engineer, Anthony Rowe, can always keep an eye on his home, even when he’s traveled to another time zone. That’s because he’s rigged his home with sensors he invented with support from the National Science Foundation. Now all he needs is a laptop to help him keep track of all his appliances – whether they are on or off and how much energy they’re using.

  • Illustration of a horse with its nose pointed towards the ground. In this position the pupil of the eye is parallel to the ground. Caption: It would enhance the effective field of view

    New research led by scientists at the University of California, Berkeley, suggests that the shape of some animals' pupils could reveal whether one is hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads.

  • Illustration of heavy rain and a dark sky with a large funnel shaped cloud over water. Caption: (narrator) Cyclones, hurricanes, and typhoons are harsh

    Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode. Moko and Totemie take a boat and travel across the lake to where the landscape is very different. Suddenly, they see a strange column twirling in the horizon. The wind is getting stronger and stronger all around them. Moko and Totemie find a tree and hang on to it as tightly as they can. The cyclone goes over their heads and they can see in the center of the column of wind. Moko thinks that if you respect the power of nature, then nature lets you see some of its secrets.

  • Aerial view of a populated island surrounded by bluish green water. Caption: Nouméa is the island's only real city

    Situated to the west of the Pacific, almost 750 miles away from Australia, New Caledonia is home to the largest lagoon on the planet. A coral universe of breathtaking beauty, the lagoon is resident to countless marine species. Part of the “Sites for Your Eyes” series.

  • Map of North and Central America. Different areas of the map are highlighted to indicate the habitat areas and 5 birds are superimposed on the map. The highlighted areas are concentrated in central Mexico, the west coast of the United states, and much of Canada and Alaska. Caption: they changed eye color from yellow to dark.

    Throughout North America, the species known as the dark-eyed junco exhibits striking differences in feather color, body size, and behavior from place to place. These variations among subspecies have caught the attention of biologists interested in diversification, evolution, and speciation. This segment features footage from junco habitats across the continent as researchers try to decode the riddle of the Junco’s evolutionary history. Part of Ordinary Extraordinary Junco (Chapter 3).

  • Two metal bowls with popped popcorn. One bowl is overflowing, the other is half empty. Spanish captions.

    In this chapter, the scientists will try to find the best corn to make the biggest popcorn. They will also have a lot of fun with optical illusions. And finally they will show how eyeglasses gather light by using lasers. Part of the House of Science Series.

  • Person slightly squinting. Caption: I hear that, but I probably won't remember the numbers.

    Julie loves the glorious colors associated with the sound of a rooster crowing, while Mandi remembers phone numbers by their hues. Until John read a newspaper article about synesthesia in later life, he thought that everyone saw the days of the week as various shades of blue. In this program, people with synesthesia describe their experiences and perceptions, as well as the benefits and drawbacks of having a condition in which the barriers between the senses are dissolved.

  • Illustration of a wave striking an atom. Caption: The shortest wavelength light are gamma rays,

    Dr. Michelle Thaller explains infrared light. Due to its longer wavelengths than those of visible light, infrared light is invisible to the human eye. However, special equipment exists that makes these wavelengths visible. Part of the "Ask an Astronomer" series.

  • Graphic of peaks and valleys below the surface of the water. Caption: And satellites unveil the seafloor,

    Offers a look at what kind of information satellites provide about our world. Satellite imagery has multiple uses: showing crops and pests, monitoring weather in all its forms, following forest fires and air pollutants, and more. Imagery notes climate changes, the ozone layer, and temperature of many things--all designed to predict and protect. These sensors present unusual windows to our world.

  • A mouse nibbles the food particle holding it in its claws. Caption: The nanoparticles gave the mouse the ability to see infrared.

    Infrared light is all around, and the universe literally glows with it everywhere. However, humans are not able to see infrared light because it is just outside the limits of the human eye. With a simple injection, scientists gave mice the ability to perceive near-infrared light. What does this mean for humans? Part of the "Uno Dos of Trace" series.

  • Person shining a light into someone's eye and looking closely at it. Caption: A migraine doesn't feel like a typical headache.

    This segment tackles migraine headaches and how they can interfere with daily life. Experts also discuss the triggers associated with migraines such as caffeine, dehydration, and stress. Part of the "Teen Kids News" series.

  • Closeup of the human eye. Caption: which regulates the amount of light entering the eye.

    Presents three key biological concepts about sensory responses and tropisms: the eye, nervous system responses, and plant tropisms. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level. NOTE: Dissects a horse's eye to identify functions of each part.
