Unusual Frame Materials


Unusual frame materials

Glasses frames can be made from many materials. The most common are plastic or metal frames. You can read about these in my previous blogs. However there are some people who don`t particularly like the usual frame materials. Glasses frames can be made from wood, bone and even leather; for the part at the temples at least. Some rich people can afford to purchase fully gold or silver glasses frames.

 I actually like the wooden glasses frame I think they have an interesting and unique but subtle appearance to them.

Bone is also a material used to make glasses frames. They give the glasses a very rare gleaming appearance. They are usually stark white in appearance. The white bit of glasses below are made from deer jaw bone.

Buffalo horn is another material that you can have glasses made from. The glasses adjust themselves to your body temperature, the feel completely different to any other glasses you`ve worn.

Precious stones can also be used to embed glasses frames.

Materials Used to Make Glasses Frames (2)


 Metal

Metal based glasses are also very common but more so with adults. They are harder to break and have a more classical appearance to them. They cannot be as easily coloured as plastic glasses can be. Most metal glasses are encased in a plastic frame so they can have a particular design to them but they aren`t as breakable as a normal fully plastic frame.



 The alloy (a mixture of different metals) most commonly used in the production of glasses is Monel. This is the most commonly used metal but a very small percentage of people have an allergic reaction of the sorts to this particular alloy. Their skin chemistry doesn`t agree with the alloy and spots may appear around the area of the glasses frame.

    Other metals can be used to make glasses such titanium. Its sliver-grey a metal that's lightweight, durable, strong and corrosion-resistant. It has been used for everything from the Gemini and Apollo space capsules to medical implants such as heart valves.

Materials Used to Make Glasses Frames (1)



There are many materials that can be used to make glasses such as plastic which is most commonly used in children’s glasses. The type of material used in your glasses effects the style, weight and durability of your glasses, it can even effect the colour of your glasses. These are the materials that glasses frame can be made from. The most common ones have a small bit written about them.

Plastic:

 This is commonly used in the ‘rainbow’ coloured glasses as plastic is easy to colour.  It is very cost effective for the production of eyewear and is very lightweight so children aren`t annoyed by them. Particularly popular right now are laminated zyl (zylonite, or cellulose acetate: which are types of plastic) frames that have layered colours. Look for light colours on the insides, which can make your Glasses "disappear" from your vision when you wear them. All-black frame is visible at all times on both the insides and the exterior of your glasses. Eyeglasses made of nylon first were introduced in the late 1940s. Because of brittleness and other problems, eyeglass manufacturers switched to blended nylon. Today's blended nylon frames are both strong and lightweight.

Plastic frames do have some disadvantaged as well. They are easier to break than metal glasses. They will burn but will not be ignited easily. Aging and long-term exposure to the light can cause a decrease in its durability and strength. In time the colour can also fade in glasses made from plastic.

Brief History of Glasses


The invention of the glasses originated from Europe, though claims were made that they had been invented in India beforehand. These claims were later proved as hoaxes. There have been many later developments to the modern eyeglasses which are now worn today. The first of which were made by the American scientist Benjamin Franklin who invented bifocals. Over time the invention of glasses frames began. Earlier glasses had been made in such a way that they had to be either held up to the eye to be used or they exerted pressure on the nose. Instead of using metal, inventors suggested that a ribbon be tied around the wearers head and a hat worn on top, this was done to keep the lenses in place. The modern style of the eyeglasses held by temples passing over your ears was invented sometime before 1727. It is believed that they were invented by the British optician Edward Scarlett.  This is how the invention of the modern eyeglasses came about. Today surgery can also be done to correct your vision.

Introduction

Hi I`m Ruthann and for the next couple of weeks  I will be blogging about the Geography of Glasses.


The creation of glasses came about years ago around 1268 in Germany. However the notion of glasses dates further back around the time of Emperor Nero whose tutor used globes filled with water or of pure glass to magnify the words form books. "Letters, however small and indistinct, are seen enlarged and more clearly through a globe or glass filled with water" was said by Seneca the tutor of Nero.
 Glasses can have many purposes such as sun glasses which are used to protect your eyes from sunlight. Safety glasses in science are used to protect our eyes from dangerous chemicals and other potential harm. There also corrective glasses which are the most commonly worn. In this blog will posting on how glasses got to the level they are at today. I will explain why the materials used to make glasses are used.
