Materials Used to Make Sunglasses

Course side of the optics at a sunglasses the functionality and quality plays a decisive role. Finally, it should in the summer so her main task is to protect the eyes from the harmful UV rays, also meet. If one uses the spectacle rarely, possibly, the fashion aspect in the foreground. For all other certainly worth the question about the advantages or disadvantages of each model.

Materials Used to Make Sunglasses

A pair of sunglasses is like any other glasses also, of two parts, the frame and the glass.

The frame consists of the front and the bracket. These two parts are connected to each other with the so-called strap stop which works like a hinge. If it is a spring hinge, so the advantage is that the brackets allow a slight hyperextension. In addition, the spectacle thus better suited to the respective head shape.The curves of the earpieces also ensure a better grip and secure fit.

Passing the straps of a thermoplastic material, the rounding will be specially adapted at the end of the carrier. If one is (n) in the summer very sensitive to light and often wearing sunglasses, so is the good and tight fit a very important component.
The eyeglass frames can be made ​​of plastic, metal, titanium or even wood.

Plastic:
Many manufacturers use to their models a large part of plastic, due to the great benefits that brings this material with them. It is easy, and can be designed virtually unlimited. For the support of these eyeglasses are the advantages in a high resilience in everyday life. In addition, you can see the racks themselves easily cleaned of dirt or sweat. Optimal conditions for any man who likes to be operated sporty. Particularly trendy frames are often made ​​of plastic, and are distinguished by a good compatibility. The disadvantage is to be mentioned that these plastics to be processed often worse for the producer as another raw material.

Metal:
eyeglass frames made ​​of metal have the advantage that they are very fine and thin, but still considered to be particularly robust. They are corrosion resistant and suitable for models to be gray or silvery shaded shiny.
A disadvantage of this material is that it covers only objective and neutral lines of the strap and the glass enclosures are possible.

Titan:
The processing of titanium brings advantages similar to those Metal. It is light and very stable. Also corrosion is virtually impossible.
But since many titanium alloys contain nickel, it should be noted as a disadvantage that these eyeglass frames can trigger allergies.

Wood:
Probably the least processed material is wood. One advantage is certainly the possibility of individuality and uniqueness of the many hand crafted models.
Since these glasses are made ​​by hand, is regarded as a disadvantage certain of the resulting need for higher price. In addition, several types of wood for the production are needed and complicates and slows moreover fabrication. A further drawback is that the installation of the lenses is much more complicated, since wood has less flexibility.
The lenses of sunglasses are made ​​of either plastic or mineral glass.

Plastic:
The advantages of plastic lenses are their lightness and that they are unbreakable. Built-in filters protect the eyes in summer from the harmful UV light. A toning and coloring is possible in any color. A splintering of the glasses can be eliminated.
As a disadvantage must be considered that the plastic lenses scratch easily. Important for anyone who needs a normal glasses, is that these glasses are not suitable for sunglasses with high diopter.

Mineral glass:
The advantages of this material are in a high scratch resistance. In addition, the texture of this glass enables a fusion of different Sehzohnen, and can therefore be used for the production of multifocal glasses.
Mineral glass is thinner than plastic lenses and therefore well suitable for high diopter values. In addition, mineral glass is also priced lower than plastic, but also heavier.
A drawback is therefore that the total weight of the glasses is higher. The more pronounced the visual defect, the more difficult is the model.
During exercise in the summer or in sports accidents, there is a possibility that the sunglass lenses made ​​of mineral glass shatter and cause injury to the eye are possible.
