The style of sunglasses on the market can be varied and varied, and the prices are different. So what is the difference between dozens of sunglasses and hundreds of thousands?
The quality of sunglasses is mainly to see the quality of the sunglasses and the advantages and disadvantages of the frame. Today, Xiaobian will come to tell you how to buy high quality sunglasses, and the difference between expensive and good?
What are the differences between tens of pieces and hundreds of pieces of sunglasses?
Identify the quality of sunglasses
When buying sunglasses, it is important to check whether it has UV protection, but also pay attention to distinguish the inherent quality of the lens.
The pros and cons of the lens is a decisive factor in measuring the quality of a pair of glasses. Therefore, consumers must be careful when purchasing lenses. The lens is scratch-resistant, but relatively speaking, its weight is heavier than that of other materials, and it is also easy to break. Polymer resin lens: This lens component is lighter than glass lens, impact resistant, not easy to break, but the hardness is low, and it is easy to have scratches.
To measure the quality of a pair of sunglass lenses, in addition to the material, it depends on the refractive index of the lens. The higher the refractive index, the thinner the lens and the higher the price.
Such as the optical characteristics of the lens: sunglasses are flat mirrors, can not have diopter, and should not have optical discriminating methods that affect vision, the simple identification method is to put sunglasses in front of the eyes, through the lens to observe distant targets, such as window frames Or the door frame, etc., then move the glasses up and down, what you are looking at should not have swing and wave deformation.
Most of SOJOS’s sunglasses are polarized lenses. What are polarized lenses?
Invented by Dr. Jane Lan (born in 1909 in Connecticut, USA) Dr. Edwin Land was fascinated by optics for the first commercially available polarized when he was young. In 1937, Polaroid Polaroid was founded. Polaroid is the creator and one of the leaders in polarized lens technology. As the inventor of the polarization, Polaroid’s research center in Europe has introduced a new generation of polarized lenses to the market through continuous innovation and development. Through a series of rigorous tests, it ensures high standards and optical stability of polarized lenses.
In order to enable most consumers to experience the best valuable sunglasses, SOJOS sunglasses use the best craftsmanship and set the lowest price.
Most poor quality sunglasses generally use fake lenses.
If you wear it for a long time, the glasses will be sore and uncomfortable, and even some will cause vision damage. When buying sunglasses, in order to distinguish the quality of the lens, you can align the sunglasses with the light, check whether the lens surface of the sunglasses is smooth, no bumps, no wear marks and bubbles.
Usually a good frame is comfortable to wear, does not affect the skin, and will hold up well over time. The inferior frame is the opposite. Regarding the metal sunglasses frame, we should pay attention to whether there is a crack in the solder joint, whether it is strong or not; can use the nail to rub it to see if there are any scratches on the paint surface; for the sunglasses frame of the plate material, carefully observe whether its surface is Plastic particles, whether there are scratches, whether the rough frame is distorted, etc.
