Bausch + Lomb is conducting a voluntary recall of Peroxi. Clear 3% Hydrogen Peroxide Cleaning & Disinfecting Solution in the U. S. Discomfort is characterized by tiredness, dryness and redness. This monthly- replacement contact lens is designed to help digital device users' eyes feel less fatigued. Biofinity Energys is designed for all- day wear and uses a two- fold approach to combat device- induced discomfort: Multiple front- surface aspheric curves across the entire optical zone simulate positive power in the center of the lens, which helps reduce strain on eye muscles as a wearer's gaze repeatedly moves from screen to off- screen and back. In addition to this optimized lens design, the company's Aquaform Technology is said to attract and bind water throughout the lens material.
This serves to retain moisture even during times of reduced blinking, which is common with screen use. After one week of wear, eight of ten digital device users agreed that Biofinity Energys lenses made their eyes feel less tired, according to Cooper. Vision. The lens is designed for monthly replacement, and a phased rollout for the United States begins in July. User- Adjustable Electronic Contact Lenses May Be Available Soon. November 2. 01. 5 — Are electronic contact lenses (ECLs) in our future? E- Vision Smart Optics is developing a lens that would allow wearers to adjust the optics for focusing at near, far and intermediate distances. Electronic contact lenses would allow wearers to change focusing power on the fly. The technology already exists in other optical devices, including electronic focusing eyeglasses and augmented reality displays. But how would it work in a contact lens? The Florida- based company was issued a patent last month for the use of a flexible lens containing electro- active materials — what it's calling a . And the wearer could choose pre- set focus ranges to change the prescription quickly, to adapt to different viewing situations as they arise. According to E- Vision, the first prototype of the ECL will be available by late 2. Caution: Some Special- Effect Halloween Contact Lenses Reduce Vision Quality. October 2. 01. 5 — Special- effect contact lenses (also called theatrical lenses, Halloween contact lenses, and decorative contacts) are a popular choice among costume enthusiasts who want to dramatically alter their appearance, especially at Halloween. But beware: According to a new study, some special- effect contacts can interfere with your vision, especially in low- light conditions such as when driving at night or walking after dark. Researchers investigated changes in visual function of 3. Special- effect lens designs evaluated in the study had clear pupil zone diameters of 4. The study included visual acuity tests with a standard eye chart and measurements of contrast sensitivity and higher- order aberrations. Results showed that participants who wore special- effect contact lenses with small pupil designs (4 mm clear pupil zone) had significantly reduced visual acuity. Also, higher- order aberrations increased with special- effect designs with small pupil zones, and contrast sensitivity decreased when wearing the decorative lenses (even in normal lighting). The study authors concluded that people considering purchasing theatrical contact lenses for Halloween and other occasions should be made aware of possible disturbances in visual function these lenses may cause. Remember, just like conventional (clear or nearly clear) contact lenses that are prescribed for nearsightedness or farsightedness, special- effect contacts must be fitted by an eye care provider, and a contact lens prescription is required to purchase them. Special- effect lenses are available with or without corrective power and therefore can be worn by nearly everyone — including people with naturally perfect vision — for fun and special occasions. A report of the study appeared in the online version of British Journal of Ophthalmology in September. CDC Report: Millions Of Americans Take Unnecessary Risks With Their Contact Lenses. August 2. 01. 5 — Are contact lenses dangerous? They don't have to be — especially if you follow your eye care provider's recommendations and take common- sense precautions when wearing them. Napping while wearing your contact lenses? You're risking eye problems, including infection. Unfortunately, a new report by the U. S. Centers for Disease Control and Prevention (CDC) reveals millions of Americans who wear contact lenses do things that can significantly increase their risk for eye infections. The findings come from an online survey of contact lens wearers designed to assess the prevalence of contact lens wear and hygiene- related risk behaviors. And here's the bad news: nearly all (approximately 9. Risk behaviors reported included: Napping while wearing contacts (8. Wearing contact lenses while showering (8. Using lens storage case longer than recommended replacement frequency (8. Wearing contact lenses while swimming (6. Most of the respondents (8. According to CDC, the findings will help create prevention messages aimed at contact lens wearers, which will include recommendations to: Avoid exposing contact lenses to water of any kind (other than approved lens care solutions). Discard disinfecting solution from lens storage case after each use (don't . Overall, contact lens wearers in the United States are younger, female, more educated, and of white non- Hispanic ethnicity, compared with the demographics of non- wearers, according to the survey.

July 2. 01. 5 — Johnson & Johnson Vision Care announced a new daily disposable contact lens with an aspheric center- near design that the company says closely matches the optical design to the wearer's pupil size for better vision. The 1- Day Acuvue Moist Multifocal comes in 6. D to - 9. 0. 0D and three add powers, to give contact lens fitters lots of options to fit people with various needs. The lens's back curve design helps keep the lens centered over the pupil, with the aspheric center mimicking the natural shape of the eye's surface. Such stability can help the complex front- surface optics do their job in delivering clear vision at various distances. For comfort, a wetting agent is embedded in the lens material. And the 1- Day Acuvue Moist Multifocal blocks about 8. UVA and 9. 7 percent of UVB rays. An outer darker limbal ring adds contrast between the iris and sclera, while an inner translucent pattern adds depth and highlights to the iris.

Gel, providing comfortable vision at near, intermediate and far distances. The Life of Sir Isaac Newton (1. By Dr. Hatch - University of Florida. Newton, Sir Isaac (1. English natural philosopher, generally regarded as the most original and influential theorist in the history of science. In addition to his invention of the infinitesimal calculus and a new theory of light and color, Newton transformed the structure of physical science with his three laws of motion and the law of universal gravitation. As the keystone of the scientific revolution of the 1. Newton's work combined the contributions of Copernicus, Kepler, Galileo, Descartes, and others into a new and powerful synthesis. Three centuries later the resulting structure - classical mechanics - continues to be a useful but no less elegant monument to his genius. Life & Character - Isaac Newton was born prematurely on Christmas day 1. January 1. 64. 3, New Style) in Woolsthorpe, a hamlet near Grantham in Lincolnshire. The posthumous son of an illiterate yeoman (also named Isaac), the fatherless infant was small enough at birth to fit 'into a quartpot.' When he was barely three years old Newton's mother, Hanna (Ayscough), placed her first born with his grandmother in order to remarry and raise a second family with Barnabas Smith, a wealthy rector from nearby North Witham. Much as been made of Newton's posthumous birth, his prolonged separation from his mother, and his unrivaled hatred of his stepfather. Until Hanna returned to Woolsthorpe in 1. Newton was denied his mother's attention, a possible clue to his complex character. Newton's childhood was anything but happy, and throughout his life he verged on emotional collapse, occasionally falling into violent and vindictive attacks against friend and foe alike. With his mother's return to Woolsthorpe in 1. Newton was taken from school to fulfill his birthright as a farmer. Happily, he failed in this calling, and returned to King's School at Granthan to prepare for entrance to Trinity College, Cambridge. Numerous anecdotes survive from this period about Newton's absent- mindedness as a fledging farmer and his lackluster performance as a student. But the turning point in Newton's life came in June 1. Woolsthorpe for Cambridge University. Here Newton entered a new world, one he could eventually call his own. Although Cambridge was an outstanding center of learning, the spirit of the scientific revolution had yet to penetrate its ancient and somewhat ossified curriculum. Little is known of Newton's formal studies as an undergraduate, but he likely received large doses of Aristotle as well as other classical authors. And by all appearances his academic performance was undistinguished. In 1. 66. 4 Isaac Barrow, Lucasian Professor of Mathematics at Cambridge, examined Newton's understanding of Euclid and found it sorely lacking. We now know that during his undergraduate years Newton was deeply engrossed in private study, that he privately mastered the works of Ren. A series of extant notebooks shows that by 1. Newton had begun to master Descartes' G. Barrow, himself a gifted mathematician, had yet to appreciate Newton's genius. In 1. 66. 5 Newton took his bachelor's degree at Cambridge without honors or distinction. Since the university was closed for the next two years because of plague, Newton returned to Woolsthorpe in midyear. There, in the following 1. As he later recalled, 'All this was in the two plague years of 1. I was in my prime of age for invention, and minded mathematics and philosophy more than at any time since.' In mathematics Newton conceived his 'method of fluxions' (infinitesimal calculus), laid the foundations for his theory of light and color, and achieved significant insight into the problem of planetary motion, insights that eventually led to the publication of his Principia(1. In April 1. 66. 7, Newton returned to Cambridge and, against stiff odds, was elected a minor fellow at Trinity. Success followed good fortune. In the next year he became a senior fellow upon taking his master of arts degree, and in 1. Isaac Barrow as Lucasian Professor of Mathematics. The duties of this appointment offered Newton the opportunity to organize the results of his earlier optical researches, and in 1. Royal Society, he communicated his first public paper, a brilliant but no less controversial study on the nature of color. In the first of a series of bitter disputes, Newton locked horns with the society's celebrated curator of experiments, the bright but brittle Robert Hooke. The ensuing controversy, which continued until 1. Newton's behavior. After an initial skirmish, he quietly retreated. Nonetheless, in 1. Newton ventured another yet another paper, which again drew lightning, this time charged with claims that he had plagiarized from Hooke. The charges were entirely ungrounded. Twice burned, Newton withdrew. In 1. 67. 8, Newton suffered a serious emotional breakdown, and in the following year his mother died. Newton's response was to cut off contact with others and engross himself in alchemical research. These studies, once an embarrassment to Newton scholars, were not misguided musings but rigorous investigations into the hidden forces of nature. Newton's alchemical studies opened theoretical avenues not found in the mechanical philosophy, the world view that sustained his early work. While the mechanical philosophy reduced all phenomena to the impact of matter in motion, the alchemical tradition upheld the possibility of attraction and repulsion at the particulate level. Newton's later insights in celestial mechanics can be traced in part to his alchemical interests. By combining action- at- a- distance and mathematics, Newton transformed the mechanical philosophy by adding a mysterious but no less measurable quantity, gravitational force. In 1. 66. 6, as tradition has it, Newton observed the fall of an apple in his garden at Woolsthorpe, later recalling, 'In the same year I began to think of gravity extending to the orb of the Moon.' Newton's memory was not accurate. In fact, all evidence suggests that the concept of universal gravitation did not spring full- blown from Newton's head in 1. Ironically, Robert Hooke helped give it life. In November 1. 67. Hooke initiated an exchange of letters that bore on the question of planetary motion. Although Newton hastily broke off the correspondence, Hooke's letters provided a conceptual link between central attraction and a force falling off with the square of distance. Sometime in early 1. Newton apprears to have quietly drawn his own conclusions. Meanwhile, in the coffeehouses of London, Hooke, Edmund Halley, and Christopher Wren struggled unsuccessfully with the problem of planetary motion. Finally, in August 1. Halley paid a legendary visit to Newton in Cambridge, hoping for an answer to his riddle: What type of curve does a planet describe in its orbit around the sun, assuming an inverse square law of attraction? When Halley posed the question, Newton's ready response was 'an ellipse.' When asked how he knew it was an ellipse Newton replied that he had already calculated it. Although Newton had privately answered one of the riddles of the universe- -and he alone possessed the mathematical ability to do so- -he had characteristically misplaced the calculation. After further discussion he promised to send Halley a fresh calculaiton forthwith. In partial fulfillment of his promise Newton produced his De Motu of 1. From that seed, after nearly two years of intense labor, the Philosophiae Naturalis Principia Mathematica appeared. Arguably, it is the most important book published in the history of science. But if the Principia was Newton's brainchild, Hooke and Halley were nothing less than midwives. Although the Principia was well received, its future was cast in doubt before it appeared. Here again Hooke was center stage, this time claiming (not without justification) that his letters of 1. Newton's discovery. Newton was so furious with Hooke that he threatened to suppress Book III of the Principia altogether, finally denouncing science as 'an impertinently litigious lady.' Newton calmed down and finally consented to publication. But instead of acknowledging Hooke's contribution Newton systematically deleted every possible mention of Hooke's name. Newton's hatred for Hooke was consumptive. Indeed, Newton later withheld publication of his Opticks (1. Royal Society until Hooke's death in 1. After publishing the Principia, Newton became more involved in public affairs. In 1. 68. 9 he was elected to represent Cambridge in Parliament, and during his stay in London he became acquainted with John Locke, the famous philosopher, and Nicolas Fatio de Duillier, a brilliant young mathematician who became an intimate friend. In 1. 69. 3, however, Newton suffered a severe nervous disorder, not unlike his breakdown of 1. The cause is open to interpretation: overwork; the stress of controversy; the unexplained loss of friendship with Fatio; or perhaps chronic mercury poisoning, the result of nearly three decades of alchemical research. Each factor may have played a role. We only know Locke and Samuel Pepys received strange and seemingly deranged letters that prompted concern for Newton's 'discomposure in head, or mind, or both.' Whatever the cause, shortly after his recovery Newton sought a new position in London. In 1. 69. 6, with the help of Charles Montague, a fellow of Trinity and later earl of Halifax, Newton was appointed Warden and then Master of the Mint. His new position proved 'most proper,' and he left Cambridge for London without regret. During his London years Newton enjoyed power and worldly success. His position at the Mint assured a comfortable social and economic status, and he was an active and able administrator. After the death of Hooke in 1. Newton was elected president of the Royal Society and was annually reelected until his death. In 1. 70. 4 he published his second major work, the Opticks, based largely on work completed decades before. He was knighted in 1.
