The Eye Is a Natural Optical Tool
KEY CONCEPT The eye is a natural optical tool. BEFORE, you learned NOW, you will learn •Mirrors and lenses focus light • How the eye depends on to form images natural lenses •Mirrors and lenses can alter • How artificial lenses can be images in useful ways used to correct vision problems VOCABULARY EXPLORE Focusing Vision cornea p. 607 How does the eye focus an image? pupil p. 607 retina p. 607 PROCEDURE 1 Position yourself so you can see an object about 6 meters (20 feet) away. 2 Close one eye, hold up your index finger, and bring it as close to your open eye as you can while keeping the finger clearly in focus. 3 Keeping your finger in place, look just to the side at the more distant object and focus your eye on it. 4 Without looking away from the more distant object, observe your finger. WHAT DO YOU THINK? • How does the nearby object look when you are focusing on something distant? • What might be happening in your eye to cause this change in the nearby object? The eye gathers and focuses light. The eyes of human beings and many other animals are natural optical tools that process visible light. Eyes transmit light, refract light, and respond to different wavelengths of light. Eyes contain natural lenses that focus images of objects. Eyes convert the energy of light waves into signals that can be sent to the brain. The brain interprets these signals as shape, brightness, and color. Altogether, these processes make vision possible. In this section, you will learn how the eye works. -

Benjamin Franklin People Mentioned in Walden
PEOPLE MENTIONED IN WALDEN BENJAMIN “VERSE-MAKERS WERE GENERALLY BEGGARS” FRANKLIN1 Son of so-and-so and so-and-so, this so-and-so helped us to gain our independence, instructed us in economy, and drew down lightning from the clouds. “NARRATIVE HISTORY” AMOUNTS TO FABULATION, THE REAL STUFF BEING MERE CHRONOLOGY 1. Franklin was distantly related to Friend Lucretia Mott, as was John Greenleaf Whittier, Henry Adams, and Octavius Brooks Frothingham. HDT WHAT? INDEX THE PEOPLE OF WALDEN: BENJAMIN FRANKLIN PEOPLE MENTIONED IN WALDEN WALDEN: In most books, the I, or first person, is omitted; in this PEOPLE OF it will be retained; that, in respect to egotism, is the main WALDEN difference. We commonly do not remember that it is, after all, always the first person that is speaking. I should not talk so much about myself if there were any body else whom I knew as well. Unfortunately, I am confined to this theme by the narrowness of my experience. BENJAMIN FRANKLIN WALDEN: But all this is very selfish, I have heard some of my PEOPLE OF townsmen say. I confess that I have hitherto indulged very little WALDEN in philanthropic enterprises. I have made some sacrifices to a sense of duty, and among others have sacrificed this pleasure also. There are those who have used all their arts to persuade me to undertake the support of some poor family in town; and if I had nothing to do, –for the devil finds employment for the idle,– I might try my hand at some such pastime as that. -
Contact Lenses
Buying Contact Lenses Some common Questions and Answers to help you buy your lenses safely Wearing contact lenses offers many benefits. Following some simple precautions when buying lenses can help to make sure that you don’t put the health and comfort of your eyes at risk. The British Contact Lens Association and General Optical Council have put together some common questions and answers to help you buy your lenses safely 2 Images courtesy of College of Optometrists, General Optical Council and Optician How do I find out about wearing contact lenses? ● If you want to wear contact lenses to correct your eyesight, you must start by consulting an eye care practitioner for a fitting. Only registered optometrists, dispensing opticians with a specialist qualification (contact lens opticians) and medical practitioners can fit contact lenses. Fitting includes discussing your visual and lifestyle requirements, an eye examination to make sure your eyes are healthy and find out if you’re suitable, and measurements of your eyes to ensure the best lens type, fit and vision, before trying lenses. Once you have worn the lenses, you should have the health of your eyes checked again. You will also need to learn how to handle and care for your lenses. Your practitioner will advise you when you should wear the lenses and how often you should replace them. When is the fitting completed? ● Your prescribing practitioner will tell you when the fitting is completed. How long the fitting takes will depend on your lens type and your eye health. Don’t forget that, once fitted, you will need to have regular check-ups to make sure your eyes are healthy and to get the best from your contact lenses. -

Media Laboratories The FlashPoints series is devoted to books that consider literature beyond strictly national and disciplinary frameworks, and that are distinguished both by their historical grounding and by their theoretical and conceptual strength. Our books engage theory without losing touch with history and work historically without falling into uncritical positivism. FlashPoints aims for a broad audience within the humanities and the social sciences concerned with moments of cultural emergence and transformation. In a Benjaminian mode, FlashPoints is interested in how literature contributes to forming new constellations of culture and history and in how such formations function critically and politically in the present. Series titles are available online at http://escholarship.org/uc/flashpoints. series editors: Ali Behdad (Comparative Literature and English, UCLA), Founding Editor; Judith Butler (Rhetoric and Comparative Literature, UC Berkeley), Founding Editor; Michelle Clayton (Hispanic Studies and Comparative Literature, Brown University); Edward Dimendberg (Film and Media Studies, Visual Studies, and European Languages and Studies, UC Irvine), Coordinator; Catherine Gallagher (English, UC Berkeley), Founding Editor; Nouri Gana (Comparative Literature and Near Eastern Languages and Cultures, UCLA); Susan Gillman (Literature, UC Santa Cruz); Jody Greene (Literature, UC Santa Cruz); Richard Terdiman (Literature, UC Santa Cruz) A complete list of titles begins on page 235.

Spectacles of the Past by Carrie Crane
Spectacles of the Past by Carrie Crane In the United States, 143 million adults wear prescription eyewear (64% of the adult population). This is big business. The U.S. market for spectacles, not including sun glasses was 13.11 billion dollars in 2019. And while the numbers have been increasing in modern times, there have always been a significant percentage of the population who suffer from either myopia (nearsightedness) or hyperopia (farsightedness). And added to that, there are those who suffer presbyopia, the loss of near vision as one ages.1,2 It was this last condition that was the first vision hinderance to be address with a visual aid. The earliest known form of reading assistance is the reading stone, which dates back to 1000 BC and was a hemispherical shaped piece of polished quartz or glass and served to magnify something that it was held directly up against.3 This suggests there was a rudimentary understanding of the magnifying properties of curved glass but this was just the beginning. It was the Italians, in the 13th century that first created something similar to spectacles. Blown glass lenses were attached to wood, leather or horn frames and held before the eyes with a handle or hinged in the middle and precariously arranged on the bridge of the nose. These were used as reading aids only and it was another 200 years before the understanding of light refraction through a lens was understood well enough to create lenses that would help those suffering from myopia. It took almost 500 years from the development of spectacles for someone to devise a better way to keep them on the face. -
