How to choose handmade frames with good quality?

Handmade glasses frames is pretty light and the skin is not sensitive to its materials, thus it earns its fame all over the world. Now the handmade frame has broken the confinement of its style in the past and there appear various beautiful colors and all kinds of styles that amaze people greatly. We may say that handmade frame has become the mainstream of advanced frames recently.

But the handmade frames in the market are mixed with both good and bad. Then how to tell the good from the bad is never easy. Let us begin with the basic part of the handmade frame---the materials.

• Nowadays, the material of the frame is mostly the acetate fiber, and there are a few advanced frames are made of propionic fiber. While the handmade frame of acetate fiber is divided into the injection mold and pressing and grinding mold. We can know from the name of injection mold that it is made through mould casting. But now the majority of handmade frame belongs to pressing and grinding mold. In the terms of the origin of plates, France and Italy are the best and Japan is good. Therefore, the material of many advanced handmade frames is from these places and the quality could be trusted.

The process of frames. A good processing technique would not only make the frame comfortable to wear but also represent your style as an important ornament. Recently, there are five processing techniques are used in the formation of frames.

The first is the splicing technique which means to combine plates of different colors and materials together to form a temple;

The second is engraving technique which means to engrave all kinds of pictures on the plate through computer based on the original colors and styles of the plate;

The third is inlaying technique, which means to inlay various pictures on the plate without any seals and without damaging the smoothness of the plate. This technique abandons the traditional sticky and drilling method and provides a new thought and point for diamond processing;

The fourth is the lacquer technique, which means to lacquer at the temple of a frame by using a lacquer pen. In this way, the paint would spread evenly on the plate;

The last is corrosion technique. By using corrosive agent，the plate would change its color, let’s say from bright to dark.

It is a sure thing that the techniques of handmade frames with poor quality would be simple, without using the advanced techniques like inlay or splice. While for the advanced handmade frames, various techniques would be adopted in order to create a wonderful collocation of colors and effect.

Plate is an environment-friendly product, the material of which would not be influenced by the skin or body secretions. Therefore, it is totally healthy to our skins and is popular among consumers. And the features of being vitreous, colorable, smooth, and non-aging make it possible for manufacturers to process the plate with creativity. And finally, there appear so many kinds of acetate glasses frames with different styles for you to choose.

CR-39 began the change of optical lenses from glass to plastic materials. It is lighter weight, more impact resistant than glass lenses; thus, becoming a popular type of material used in single vision, bifocal, and multifocal or progressive lenses.

Material is low price and easy to manufacture. It is often preferred by individuals on a tight budget. However, because of its 1.50 index, customers with high prescription powers are recommended to use higher index lenses such as 1.56, PC, 1.67, or 1.74 lenses.

CR39 Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: CR39 lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: CR39 lenses have much lower internal reflection and surface glare than glass materials.
Tinting: CR39 lenses are great for tinting. Lenses can be tinted to virtually any color. Even lenses with variable thickness are able to be tinted evenly.

If you want thinner, lighter lenses, and have an milder prescription, then mid index lenses are the way to go. As prescription increases, the lenses become thicker. Thicker lenses increase internal reflections that reduce vision quality. Furthermore, thicker lenses add to the weight of each pair of glasses reducing comfort. Mid-Index lenses refract the light at a greater angle allowing the wearer to have a beautifully thin and light pair of glasses.

Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: Mid Index lenses have much lower internal reflection and surface glare than glass materials.
Tinting: Mid index lenses are also tintable, so you can get that pair of sunglasses you’ve been eyeing for so long.

Polycarbonate lenses has a high index of refraction 1.59 and low density making PC lenses 20% thinner and 25% lighter than regular plastic lenses. Polycarbonate lenses are the most impact resistant lenses on the market. Therefore, it is the industry standard for safety goggles, and highly recommended for kids' lenses.

Polycarbonate Lenses Features are:

Impact Resistant: Polycarbonate material was originally made for uses on canopies covering fighter planes and then made its way into space on astronaut visors and space shuttle windshields. Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.
Scratching: The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities.
UV Protection: Polycarbonate lenses inherently carries UV protection properties that blocks nearly 100% of the UV rays from entering the back of the retina.

If you want thinner, lighter lenses, then high index lenses are the way to go. As prescription increases, the lenses become thicker. Thicker lenses increase internal reflections that reduce vision quality. Furthermore, thicker lenses add to the weight of each pair of glasses reducing comfort. Hi-Index lenses refract the light at a greater angle allowing the wearer to have a beautifully thin and light pair of glasses.

High Index Lenses Features are:
