The eyes, referring to the window of soul, are the largest window for people to identify the world. Unfortunately, not everyone has a pair of bright healthy eyes. Nowadays, with the poor conditions and bad living habits, there are approximately one-third people of the population suffering from myopia according to a recent survey. To this end, various glasses companies have been set up to meet patients’ requirements. Different styles, bands and colors are all available, with the price ranging from a few US dollars to several thousand. However, in face of such many eyeglasses in today’s market, customers become more confused. Most of them have no idea of how to start with and how to identify the quality. In view of this, here I would like to introduce a few approaches to check the quality of glasses.
First, to observe the out appearance:
Â
1). Electroplating, paint coating, polishing and other plate surfaces should be in uniformity of color, without obvious defects, spots and scratches.
Â
2). Lenses, frame legs and other printings, laser and engraving strokes must be clear and smooth, easily identifiable and difficult to come off.
Â
3). As for the lens, its color has to be correct, no scratches and bubbles; meanwhile, the color of gradual lenses should be natural, with left and right one in symmetry.
Â
4). It is necessary to hold eyeglasses in face of fluorescent lamps, so as to make the reflective strip gently move. If the image does not appear wavy or distorted shape, it indicates that there is no stress of the lens.
Â
5). With regard to the quality of frames, customers must pay special attention. In general, there are three kinds of materials: metal frame (including alloy, pure titanium, B titanium, and so on, with a big difference in the price); plate frame (resin, injection molding); metal-binding plate (usually the metal frame, plate legs).
Â
While choosing metal spectacle frames, people can gently curve the leg to see the extent of its flexibility; commonly, the half-soft material is produced by alloy based on the brass; and stainless steel has a larger hardness. In addition, the high-quality
eyeglass frames generally use nickel alloy or titanium material, with a high strength, high flexibility, and good corrosion resistance; more importantly, they can endure for a long time, no deformation.
Â
Second, customers need to look at packaging and geographical indications carefully.
A good pair of eyeglasses has definitely a complete package, tag, or descriptions; on the tag, product code and instructions, there must be detailed product description, industry quality standards and contacting content of the dealer or manufacturer.
Â
Last, to try on eyeglasses in person:
High-quality glasses will certainly form clear and true images. At the same time, the wearers must feel rather comfortable, without any oppressive sense on bridge of the nose, temples, ears and etc.
Â
In conclusion, customers, when selecting
eyeglasses, should not only consider the frame size, shape, complexion or fashion to wear out the temperament. More importantly, people must attach great importance to glasses’ quality, which is closely related to wearers’ health.
