Nowadays, it is estimated that more than 100 million people around the world wear contact lenses. These items are very popular and technology improves them daily making them even more desirable.

Why do people wear contact lenses?

There are people who wear contact lenses, instead of glasses, for esthetical reasons. They like themselves better with contact lenses than with glasses. Another reason that determines people to wear contact lenses is the cosmetic one. There is a great variety of decorative contact lenses that can change the eye’s appearance. And there are those who appreciate their practical side. They cannot play certain sports with glasses; they use devices that are incompatible with glasses etc. There is that category of people who are forced to wear contact lenses for therapeutic reasons. In their case, the contact lens is not an option. The contact lens can be a bandage in the healing process of different diseases or injuries of the cornea and it is a luxury that heals. There is also a combination between the two reasons - colour lenses with correction power which actually please a lot of persons.

The first contact lenses ever made were developed out of glass. After that, new types appeared, as the ones made of Plexiglas and the rigid gas permeable ones, but, nowadays, the soft contact lens is the most appreciated. Modern materials include silicon hydrogel or other plastic polymers like etalficon A, galyficon A, senofilcon A (used in the fabrication of Acuvue contact lenses). Rigid gas permeable contact lenses are recommended to the persons with dry eyes as these lenses contain no water that could evaporate during the wearing.

If you decide to wear contact lenses, you first have to go to an ophthalmologist, no matter what your reason may be. The doctor will be the one to decide which type of contact lenses fit your eyes best. Different factors will be considered for the prescription of a certain contact lens: the material (the silicon hydrogel is one of the newest discoveries in the field), the wearing time (daily wear, extended wear or continuous wear), the shape (spherical, toric or multifocal) and many more. Depending of the material, the contact lens can be either rigid or soft. The rigid one can be gas-tight or gas-permeable, but the soft one is always gas-permeable. There can also be a further classification made on the moisture content, on the amount of water in the contact lens.

The wearing time

A daily contact lens is safer as the risk of infection is lower than at the long term contact lens. This type does not require cleaning, being single-use only. It is sterile. And it even keeps you away from spending money on cleaning or storage solutions. On the other hand, the extended wear type of contact lenses allows people to easily wear contacts for a longer period while allowing oxygenation (they usually have a high oxygen permeability rate). Some people prefer them as their convenience is obvious, but the risk of infection is higher than at the daily type of contact lenses due to the bacterial stagnation, dust accumulation and so on.

One of the most popular contact lenses brand in the world is Acuvue, produced by Johnson & Johnson’s subsidiary Vistakon Company. They provide both vision and esthetical contact lenses. They design disposable lenses, making types that are to be replaced every two weeks (Acuvue, Acuvue 2, Acuvue 2 Colors, Acuvue Advanced and Acuvue Oasys) or less (1-Day Acuvue). They’ve also started making extended wear lenses.

Where to buy them from

Contact lens quality is very important. Low-quality contact lenses can damage the eye, causing irritations or hurting the eyelid or the cornea. Attention must be paid to the way the lenses are worn, kept and cleaned because, even if they are high-quality, they present different risks. So, the contact lenses must be bought from specialised stores after consulting a doctor. Places where these items are available can be found anywhere as the contact lenses are very popular. Another tendency is to acquire them from an on-line store. This method can even be less expensive and still offer the same quality. You just need the prescription. But be careful and only choose reputable stores. Your health is at stake.

Having A Diamond Is A Symbol Of Forever And Eternity

By Mel Carver

Diamond is perceived as the most precious of all precious stones and is peerless. It is a woman’s best friend and a symbol of love. It shines and glitters and symbolizes purity and strength.

In ancient times, a diamond was considered to be a sign of magic, sanctity, healing, energy, happiness, beauty, and longevity when used, but the saying goes that a diamond is poison when consumed. It was known for its goodness and power to remove all evil. In today’s world, a diamond is regarded as a status symbol, an ornament of beauty worn by the rich and depicts a luxurious lifestyle.

A diamond is forever. You would have heard this. The reason for this saying is because it is the hardest natural material and very difficult to break. It is also a good conductor of heat and a nonconductor of electricity. It is another form of dark carbon.

Time was when diamond jewelry was only seen in royal portraits or in the beautifully designed catalogues and books. Today, sales of diamonds have taken a dramatic upward turn with branded diamond jewelry being available to millions of women. This treasured stone of romance and power has become very popular over the centuries.

A diamond is available in all shapes and colors, in fact more so than other gems. The weight measurement of a diamond is the ‘carat’. The larger the diamond, the more the carat. Big sized diamonds are a rarity and the value increases as the size gets bigger.

Diamond jewelry is the most expensive types of jewelry. Diamond pendants and rings are a craze, especially engagement rings. Diamonds are usually set in gold, white gold, silver, or platinum, the latter being more expensive. The combination of pearls and diamonds is a delight to the eyes.

“The rarest things in the world, next to a spirit of discernment, are diamonds and pearls.”

By Jean de la Bruyere

There are several innovative ways that diamonds are being used, which includes imbedding them in watches too. These watches though expensive are a great gift for big occasions for loved ones when you are on the lookout for expensive gifts.

Grading of diamonds is something the one needs to know. The colors are graded from D to Z, with the lesser color being higher in value. Color D is the rarest and is colorless with a blue tinge. Since colors filter light, the reflected light is less than a colorless diamond.

For the sake of some light hearted talk on diamonds, lets delve into some superstitions that were prevalent earlier on. Diamonds that have a red or yellow hue were thought to be good for a king, because they were considered auspicious.

The white hued diamond was said to be perfect for anything religious or spiritual. The yellow hued one was said to be the one for prosperity and success. Black hue was thought to be suitable for those that are in smaller jobs. Women who wanted to give birth to sons were asked to wear a white diamond with a small black hue. It was also stressed that one should never wear a blemished diamond as it brings bad luck to the person wearing it. All these may sound like unbelievable superstitions to the nonbeliever, but these were followed quite strictly earlier. But then if you go to see, even in the modern world, in some countries, many people will not wear a diamond unless they get it checked to see if it is the right one for them.

Interesting facts aren’t they. A diamond has an indescribable aura surrounding it, and it is fascinating to learn about it.
