Lazy eye is a disorder of the coordination between the eye and the brain, usually beginning in childhood. This disorder causes the body to prefer one eye over the other. It is known medically as amblyopia.
Lazy eye is characterized by poor or blurry vision in an eye that otherwise seems normal.
Someone with lazy eye experiences no transmission or poor transmission of the visual image from the eye to the brain for a period of time during early childhood. Lazy eye usually only affects one eye but it is possible to be amblyopic in both eyes if both are similarly deprived of a good, clear visual image.
Studies estimate that about one to five percent of the population suffers from lazy eye. It is believed that three percent of children under six have some form of amblyopia. Many people who are afflicted by lazy eye, especially those with a mild case, aren’t even aware they have it until they are tested at later ages. This is true because vision in their stronger eye is normal.
A severe case of lazy eye, however, can be associated with other visual disorders, particularly poor depth perception.
Lazy eye cannot be corrected by glasses or contact lenses, and is not due to any eye disease. The brain, for some reason, does not fully acknowledge the images seen by the amblyopic eye.
Many people think someone who has a crossed or "turned" eye has lazy eye. However, "crossed eyes" is actually a different eye condition known as strabismus.
Because of this misunderstanding, many people describe someone who has "crossed eyes" as having a lazy eye.
The most important means of determining if someone has lazy eye or amblyopia is a series of special visual acuity tests. The "20/20 letter charts" currently used by schools, pediatricians and many doctors are generally not sufficient for diagnosing lazy eye.
Since lazy eye usually occurs in one eye only, many parents don’t realize their child may have it. A large number of kids with lazy eye go unnoticed until they have their eyes examined when they get older. Therefore, comprehensive vision evaluations by a trained and qualified vision professional are a smart idea, even for infants and pre-schoolers.
Treatment options for lazy eye include glasses, drops, and certain vision therapies, possibly including the use of a patch.
Recent medical research has shown that lazy eye can be successfully treated up to the age of 17. As the patient grows older however, successful treatment of lazy eye requires more intense effort, including vision therapy. Improvements are possible at any age with proper treatment, but early detection of lazy eye still offers the best chance of a positive outcome.

Health Care and Nurse Staffing growing business sectors
How To Start Your Own Nursing Staffing Agency is a comprehensive guide on how to start a Nurse Agency, Nursing Registry, Nurse Staffing Agency, Healthcare Services, Homecare Services, Nursing Home, or become an Independent Nurse Contractor, Independent RN Contractor
It’s no secret that the United States has a nursing shortage, one that promises to grow to alarming proportions. Too many nurses are retiring, and too few are entering the profession. To compound the problem, within the next 5 to 10 years, over 76 million Baby Boomers are scheduled to retire from the workforce, with only about 44 million Generation X'ers available to pick up the slack. This will soon place unprecedented demands for services on a health system that is already stretched thin.This shortage of allied healthcare professionals, especially nurses have a created a new boom to the nursing agency, nurse registry business, supplemental staffing agency for medical professionals, permanent placement medical recruiter, or starting a business in homecare and staffing pool. The medical staffing industry will continue to grow because of the upcoming baby boomers, and the current supply of nurses are dwindling. The average age for nurses are in the forties, and they are not being replaced by the new generations.
So if you consider owning your own business as a way to:
Work for yourself.
Stop commuting.
Work from home
Spend more time with family.
Be successful
Gain more time and money
Set your own hours.
Entrepreneurs have made lucrative business in nursing agency, nursing registry, homecare business, medical recruiter recruiting, or as independent nurse contractor in their own field.The time is now for entrepreneurs to start a nursing agency,nursing registry business, operate a homecare business, or as a medical recruiter or just become an independent healthcare contractor. By being an independent healthcare contractor, you are bypassing the agency and are self employed. Healthcare facilities are the clients. Homecare are regulated by all levels of goverment from local to fedeal level. Homecare levels of regulations depends on the category of service provided to clients. Homecare services ranges from providing just companions or the more medically needed clients such as terminally ill clients. Homecare services can be in the form of social service, non-medical, and medical services.
A nurse recruiter is a recruiter that finds qualified nurses to fill permanent positions in health care facilities for a RETAINED FEE usually 25 - 30% of the nurses annual income.

Which Magnets are most effective for Magnetic Therapy Healing
Magnetic therapy has gained a lot of interest from the press in the last few years. This article looks at what are the most effective magnets for magnetic therapy healing. First lets discuss the different types of therapeutic magnets.
Not all magnets are created equal. Magnets come in many shapes and forms. Magnets are used for hundreds of applications from large industry purposes like the automotive industry to domestic applications such as audio speakers; you will even find them in your television. With so many different types, shapes, and strengths of magnets it can be easy to mistake an industrial magnet for a healing magnet. I will discuss the difference between the various materials magnets can be made from and their applications.
Ferrite magnets
Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets. They are made from strontium carbonate and iron oxide both of which are readily available and low in cost. Even though they exhibit low magnetic fields (compared with other permanent magnet materials),ferrite magnets are widely used for industrial and domestic purposes. Ferrite magnets have good resistance to demagnetization, excellent corrosion resistance and the biggest advantage of such economic cost.
Ferrite magnets are made in many shapes and sizes, cylinders, bars, discs, horse shoes and rings.
The positive benefits of ferrite magnets are
• They retain their magnetism for a very long time.
• They have a high stability and do not demagnetise very easily even in high temperatures.
• They are relatively low cost to produce.
• They can be manufactured to be flexible, by mixing the ferrite with plasticized rubber compounds, which creates a bendy and pliable magnet.
The main drawback of ferrite magnets is that they are quite fragile and tend to break easily, so they should be handled with care.
Ferrite magnets are used for healing purposes. They are commonly found in magnetic therapy wraps, straps, magnetic bedding and shoe insoles (using flexible ferrite magnets). Whilst ferrite magnets will keep their magnetism for a very long time you must always be careful to ensure that their strength is adequate. Each magnet should be at least 800 gauss. You should also be wary of products that could be easily damaged as once the magnets are broken the magnetic device should be discarded.
Neodymium magnets
Neodymium magnets are a member of the rare earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention, first manufactured in 1984 and have only recently become affordable for everyday use.
Neodymium rare earth magnets have a high resistance to demagnetization, unlike most other types of magnets. They will not lose their magnetization around other magnets or if dropped. They will however, begin to lose strength if they are heated above their maximum operating temperature, which is 176°F (80°C)
If you have never handled neodymium magnets before, you will be amazed at their strength. Neodymium magnets are over 10 x stronger than the strongest ceramic magnets. If you are currently using ceramic magnets in your project, you could probably use a much smaller neodymium magnet and have greater force.
Neodymium magnets also have some limitations due to their corrosion behaviour. In humid applications, a protective coating is highly recommended. Coatings which have been used successfully include E-coat (a liquid dip epoxy coating), dry electrostatic spray epoxy, nickel plating and combinations of these coatings. Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature performance.
Just like ferrite magnets neodymium magnets come in the same wide array of shapes and sizes, but because of their greatly increased size it is possible to use a measurably smaller neodymium magnet and still have an equal or greater strength than that of a ferrite magnet. This is one of the main reasons why neodymium magnets are much more widely used for healing purposes than ferrite, as a much smaller and lighter weighing magnet can be used.
The positive benefits of neodymium magnets are:
• They are the strongest magnets available approximately 10 times stronger than ferrite magnets.
• They are very lightweight.
• They do not demagnetise very easily and can with stand temperatures up to 80 C.
• They can be manufactured to a very small size e.g.2mm x 2mm and still have a strength of several thousand gauss.
The main drawback of neodymium magnets is that they have a low resistance to corrosion. To prevent corrosion from water, they must be coated with plating or an epoxy resin.
Neodymium magnets are used for all magnetic therapy healing applications. They are the first choice due to their strength and size. They will also stay magnetised for at least 10 years, so they are a very economical choice for users. Most good quality magnetic therapy jewellery, straps, wraps and bedding will contain neodymium magnets
