The United States gentleman of science, Benjamin Franklin, who persevered both nearsightedness as well as presbyopia, devised bifocals in 1784 to avoid having to frequently switch between two sets of glasses.

The 1st lenses for rectifying astigmia were constructed by the British astronomer George Airy within 1825.

Along the history of bifocals, the building of spectacle frames also developed. Early on oculars were contrived to be either held in place with hand or by maintaining force on the nose. Girolamo Savonarola advised that oculars could be held in place with a ribbon passed over the subject’s head, this in turn fastened by the weight of a hat.

Entering modern bifocal history, the contemporary fashion of bifocal reading glasses supported by temples passing over the ears, was produced in 1727 by the British lens maker Edward Scarlett. These designs were not at once prosperous, however, and assorted styles with attached handles like “scissors-glasses” and lorgnettes stayed fashionable throughout the eighteenth and into the early nineteenth century.

In the early 20th century, Moritz von Rohr at Zeiss produced the Zeiss Punktal spherical point-focus lens system which dominated the eyeglass lens domain for many years.

Despite the improving fame of contacts and laser restorative eye surgery, eyeglasses stay quite common, as their engineering has continued to evolve. For example, it’s currently possible to buy frames constituted of special memory metal alloys that return to their correct configuration after being bent. Other frames have spring-loaded hinges.

Glasses have come a long way, haven’t they? In fact, today you can even buy rimless eyeglasses.

Most of these designs are also distinctly better able to resist the stresses of day-to-day wear as well as the occasional accident. Modern frames are likewise frequently made from robust, light-weight materials like titanium alloys that weren’t obtainable in earlier days.

Commercial Millions

Some people are profitting big during this recession and downturn in the real estate market.

While millions of Americans are suffering economically, some ordinary folks are making huge sums of money combining two things you’d least expect: Real estate and the recession. As the housing market continues to plummet, a few commercial real estate asset classes are skyrocketing and some folks have learned how to acquire them with no money, credit or previous real estate experience.

These rags-to-riches stories are using two very clever and patent pending strategies taught by Jason Gilbert at the Commercial Training Institute. One strategy is used for land and the other for income property.

Master Lease Options

For income property, students learn to locate properties that perform better in a recession but won’t sell because of high vacancies due to poor management or marketing.  Instead of buying them, the students lease the entire building, hire a local expert to fix the management or marketing problem, and pocket 100% of all the new income which is can easily be $10,000 to $50,000 per month on small to mid size properties.  The student also gets an option to buy the property at today’s value, then sells or exercises the option to buy it when it’s worth much, much more and fully performing. Called “Master Lease Option”, it’s literally a try-before-you-buy strategy that eliminates most of the risk and requires no money to get in the hot commercial real estate game.  If the deal turns out to be a dud, you aren’t stuck with it as the new owner and don’t wind up one of those motivated, distressed sellers.  You don’t own the property until it’s worth far more than your option price and you’ve had time to test drive it a while.

Joint Venture Facilitation

For land deals, students locate owners of prime commercial land and simply get them to agree to partner with a developer. The owner makes much more money vs. a sale, and the developer doesn’t have to buy the land and can get easy development financing, which otherwise might be impossible due to the credit crunch. The best part is the CTI student gets a piece of ownership of the development for simply locating and bringing both parties together, thus avoiding all the time, expertise, risk and money required to buy and develop land.

A yeast infection is not an early sign of pregnancy, and the existance of the condition cannot cause a pregnancy test to be erroneously positive either. Usually, only pregnancy causes positive test results. A pregnancy yeast infection can be caused by being pregnant (or other hormonal changes) though.

Is Pregnancy Possible with a Yeast Infection?

Yeast infections cannot harm your chances of getting pregnant. There are some people that say if you have the infection for a long period of time without it being treated it can cause problems, but this is extremely rare and highly unlikely.

Is It Common During Pregnancy for a Yeast Infection?

It is said that 20% of woman will get a pregnancy yeast infection because of increase in hormones and bacteria.

It is generally not harmful to an unborn baby but should be treated more carefully, so you won’t pass the infection to your baby during the birth. Left untreated, the baby could develop the yeast infection in the form of thrush in the mouth. This is not dangerous to the baby and is easily treated should it occur.

What Are The Symptoms?

The symptoms of a pregnancy yeast infection generally build up over 1 to 3 days, and include an intense vaginal itch, irritation, soreness, burning and redness in the vagina, and a thick, white vaginal discharge. If you have any or all of these symptoms, it is advisable to seek further advice and guidance from your local physician. Don’t leave it unchecked.

How Do You Treat a Pregnancy Yeast Infection?

Yeast infections may be harder to control when you’re pregnant. They may require frequent treatment or longer treatment (10 to 14 days instead of 3 to 7 days).

Vaginal creams or suppositories used for treatment are safe during pregnancy, although most physicians recommend avoiding treatment during the first trimester. If you develop a yeast infection, it is safe for you to use over-the-counter products, such as Monistat. However, if you are early in your pregnancy (i.e. before 12 weeks), use the cream externally only. After 12 weeks, it is safe to gently use the applicator internally.

If you don’t have success with over-the-counter medication, you may want to try Boric acid, which is very mild. It won’t harm you but will alter the vaginas pH level slightly discouraging yeast growth. Probiotics are also useful in combating pregnancy yeast infections since they build up your healthy bacteria.
