Profile on Magnifier

A magnifier, usually composed of a lens and a mirror handle, is a simple optical device used to observe the details of objects. Invention of the magnifier brought a light to the researches on science and biological studies, however, there is no specific answer to when did magnifiers invented, probably not later than the 13^th century.

The reason why magnifiers are able to zoom in objects lies in the curved surfaces of lenses. According to the law of refraction, magnifiers make the image on retinas vary proportionately to the visual angles formed between the object and eyes, the bigger the visual angle, the clearer of the object. It means that, on the contrary to our normal thinking mode, more details can be observed when the object is further to the magnifier.

What’s more, magnifiers are widely applied in our daily lives. For example, when elders read, for their deterioration of eyesight, they often take a magnifier so as to see clearly words on books or newspapers. The film projector, with the application of a magnifier, shows pictures on screen big enough for people far away to make out. The camera lens are also made from magnifiers, for which reason, we can get whatever size of photos as we expect, by adjusting the distance between lens and films. Even glasses belong to one kind of magnifier.

Moreover, besides the main function of the magnifier to enlarge objects, magnifiers can also focus the sun’s rays or highlight on the paper to make fire, and the more intense the light, the easier to get fired.

Myopia: Options for Near-Sightedness

If someone had the magic cure for near-sightedness (myopia), it would be worth a fortune. I would love to have perfect vision again, the kind I had back in first grade when I passed the eye exam with unaided eyes. That was a once in a life time event for me. For the next six years, my vision deteriorated. I saw less and less of what was written on the chalkboard until my school system finally got around to giving us another eye exam, in seventh grade. I failed that one miserably, and got my first pair of glasses.

Ordinary glasses or contact lenses provide enough vision correction for millions of Americans, but these options are not satisfactory for everyone. A recent article in the medical literature reports that the highly myopic eye is considered vulnerable to a range of visual problems. With age, most of us lose some visual acuity, so we need to keep as much as we can of what we have.

Vanity stops men from getting eye checks

THIRTEEN per cent of Australian men avoid the optometrist because they’re afraid they’ll be told they need glasses, a poll shows.

One in 10 of the 609 men surveyed by Newspoll admitted they’d never been to an optometrist.

The poll, conducted for Specsavers, shows tradesmen and men who work outdoors are the worst offenders, with almost half (47 per cent) saying they haven’t had the recommended biannual eye check in the past two years.

Specsavers says the findings reveal an alarming level of apathy among Aussie males.

“Men tend to take a `she’ll be right mate’ attitude towards their health and wait until they are really sick before they seek medical intervention,” said company director and optometrist Dr Harrison Wiesinger.

He says avoiding regular eye tests places men at higher risk of suffering undiagnosed eye conditions that can cause blindness, such as glaucoma and diabetic retinopathy.

Glaucoma is estimated to affect about 300,000 Australians, with half of those people unaware they’re affected, the Centre for Eye Research Australia says.

It is the leading cause of irreversible blindness worldwide.

About 200,000 Australians are also estimated to have undiagnosed diabetic retinopathy, a disease caused by damage to the blood vessels that nourish the retina.

Early detection through regular eye checks is essential to preventing and managing both these conditions.

“Men say they aren’t having their eyes tested because they don’t have any problems seeing things but this has worrying implications when it comes to eye care,” Dr Wiesinger said.

“Many of the more serious eye conditions have very few obvious symptoms.

“By the time you notice you have a problem with your vision, you may have already suffered irreversible damage.”

Eye tests also play a role in identifying other health problems in the early stages, such as high blood pressure and tumours, he said.

“So by avoiding regular eye tests, men are also depriving themselves of the opportunity to receive early intervention that could not only save their sight, it could even save their life.”

What Are LASIK and LASEK Surgery?

In our daily lives, we often receive LASIK or LASEK surgery if we are suffering from some very common eye problems, as nearsightedness, farsightedness, astigmatism, etc. But most of us can not tell whether there is any difference between the two. In fact, they are of totally different categories, though the same laser and time are employed in the surgery.

In fact, it is true that the two are similar in some ways, but they vary very much. Let’s take a look at the names of the two abbreviated names-LASIK is abbreviated from Laser-Assisted in Situ Keratomileusis and LASEK from Laser Assisted Sub-Epithelial Keratomileusis. The foremost difference is the two surgeries are suitable for patients of different categories.

As for how the surgeries are operated, the former is suitable for eyes that are in need of little or minor correction, whereas the latter is for great correction. And another difference between the two is how to deal with the corneas. The former is for patients whose corneal tissues are thick. While the latter is thin.

Another difference is that the former surgery is suitable for patients whose corneal tissues are to be cut a lot, while the latter only a little.

Still, another difference is the thickness of corneal tissue flap, under which corneas are located. In the former surgery, the stroma tissue is treated, while the epithelial tissue is treated in the later surgery.

Some investigations have revealed that LASIK surgery can make patients felt much better than LASEK, less pain and less discomfort. On the contrary, the LASEK surgery will lead to no complications in stromal flaps.

If you are not sure about the two surgeries and you do not know which one fits you most, you can visit your eye doctors and consult some related matters with them. They can provide you the best solution for your eyes.

Massage may help reduce IOP after Ahmed glaucoma drainage device surgery

Digital ocular massage lowered IOP by 20% in some patients during the hypertensive phase after Ahmed glaucoma drainage device surgery, according to a study.

At 1 week to 8 weeks after Ahmed glaucoma drainage device surgery, 18 patients had IOP above the target range and were treated with digital ocular massage. Mean IOP decreased by 8.6 mm Hg immediately after massage, and 1 hour later it was 4.3 mm Hg lower than before the massage.

Of the 18 patients, nine sustained a 20% reduction in IOP at 1 hour. The remaining patients were considered nonresponders and were prescribed glaucoma drops. Eight responding patients who performed self-massage maintained a 20% reduction at 2 weeks, 6 weeks and 6 months after massage, although four patients were using glaucoma drops by the 6-month visit to achieve target IOP.

According to the study authors, ocular massage during the hypertensive phase of Ahmed glaucoma drainage device surgery is an effective technique to force the aqueous fluid from the eye, which may clear inflammatory material and fibrin from the tube, valve and plate area.

No massage-related complications were reported in this study, although the authors cited the need for further investigation and longer follow-up to determine the long-term benefits for bleb morphology.

Hundreds of Georgia School Children to Receive Free Eye Exams and Glasses

Blue Cross and Blue Shield of Georgia (BCBSGA) and OneSight?, a Luxottica Group Foundation have teamed to bring a regional clinic to Georgia from today, Monday, March 22, through Friday, March 26. Clayton County, Henry County and Spalding County Schools pre-selected approximately 600 students from kindergarten through high school based on their financial and vision needs to receive free vision care, including full vision exams and new eyewear. Held at the Luxottica Retail Distribution Center (100 Greenwood Industrial Pkwy, McDonough, GA 30253), local doctors, community partners, Blue Cross and Blue Shield of Georgia associates, as well as employees from LensCrafters, Sunglass Hut, Pearle Vision, Sears Optical and Target Optical will provide services and assistance during clinic hours (8 a.m. to 2 p.m. daily).

According to the Vision in Preschoolers Study, the National Institutes of Health, the National Eye Institute and NEI Clinical Studies, vision problems are the fourth most common disability in the United States, and one of the most prevalent conditions in childhood. In addition, the American Public Health Association (APHA) recently reported that one-in-four children in kindergarten through sixth grade has visual disabilities that affect their ability to learn. Some studies indicate that 80 percent of learning in children occurs visually; yet 86 percent of children do not receive a vision exam during these formative years.

“This ongoing collaborative effort to bring the Vision Van back again this year to the greater Atlanta area continues to make a meaningful difference in the lives of children who might not otherwise have had their vision needs met,” says Monye Connolly, president, BCBSGa.  “Our hope is that this service will provide these children with improved self-esteem and a better opportunity to live life to the fullest.”

“OneSight provides important opportunities through clear vision that enable children to succeed in school and ultimately, in life,” said Jane Walters, OneSight captain. “We have seen many cases where a pair of glasses has made the difference in helping a child accomplish greater scholastic success or simply see clearly for the first time. Watching a child’s face light up as the world comes into focus is something I will never forget.”

“An eye exam is one of the best forms of preventative medicine today. Good vision health is connected to overall health and well-being. Supporting OneSight’s regional clinic helps these children to more clearly experience the world around them,” said Jeff Spahr, staff vice president, Vision and Voluntary Services.

In addition to serving children in communities throughout the country with the regional clinic, OneSight also performs two-week Global Clinics designed to hand-deliver eye exams and recycled, donated eyewear to underprivileged individuals in developing countries. To date, nearly 3 million people have been helped during Global Clinics.

Theater review: Impending blindness in ‘Truce’

At first the transparent scrim separating the audience from solo performer Marilee Talkington is disconcerting. We can see and hear the graceful performer well, but the thin fabric creates an odd distancing effect. Then it becomes a powerful metaphor. And something more.

Talkington’s “Truce,” which opened Thursday at Noh Space, is a dramatic exploration of her experience going blind, and one that not only tells us about the process but also draws us into the unsettling experience. As staged by Marissa Wolf and designed by Andrew Lu, a blurry spot at the center of our vision grows with gradual but relentless meaningfulness. A blackout is more than a lighting effect.

“Fact:” – as Talkington is fond of saying – the Bay Area-raised (and American Conservatory Theater-trained) actor has been coping with a congenital, progressive form of macular degeneration (“rod-cone dystrophy”) since early childhood. Like her mother, she has no central vision and increasingly failing peripheral vision (both are legally blind).

“Truce,” written with Justin Quinn Pelegano (who directed its New York premiere) and presented by Talkington’s Vanguardian Productions, is her attempt to make peace with her loss of sight and “the woman who gave me this disease.” It’s bold, at times didactic, funny, angry, lyrical, confrontational and quite moving.

From childhood adventures with eye specialists to making her way in the worlds of theater and the blind, it’s also the story of a battle for dignity – veering between outright denial and contempt for showing weakness or anything that smacks of pity. The question of using a cane takes on illuminating symbolic weight, most eloquently in one of several stark, lovely and often scary movement passages (choreography by Sonya Smith).

Working in a svelte red dress and high boots, Talkington slips into various characters – doctors, nurses, siblings, lovers, her mother – some better defined than others. Mostly she’s herself, wrestling with progressive loss of sight and her reactions to it.

Some passages are repetitive, and some teeter on the brink of a lecture. But “Truce” is filled with engaging surprises, from the secrets of her high school basketball stardom to blind convention orgies, and evocative revelations about the deprivation of something as basic as eye contact. At its most effective, “Truce” opens windows many of us don’t even know exist.

MP’s eye surgery a success

MPP Barry Devolin learned at Ottawa General Hospital on Wednesday (March 17) that his surgery 10 days before was a complete success, his office stated in a press release Thursday.

Dr Leonard reported that the left retina was fully reattached, no scar tissue had formed, and chances for complete recovery of sight within six months were very good.

Devolin will continue to experience blurry and obstructed vision for several weeks, but improvement should progress incrementally.

“My family and I are happy to know I should make a full recovery” Devolin stated. “I want to thank the doctors and staff at the Ottawa Eye Institute for their great work, as well as those who sent me encouragement and prayers. All were greatly appreciated.”

Devolin closed by saying that “maybe it was the luck of the Irish to get this kind of good news on St. Patrick’s Day!”

Devolin will return to his full duties in Ottawa and around the riding immediately.
