Anti-fog lens cloth
Anti-fogging glasses cloth is composed of multiple layers of material pressed together, and the material absorbed a sufficient amount of antifogging agent. It can be directly wiped on any lens. Like spray anti-fogging agents, anti-fogging time is relatively short, and can not be wiped or washed. Long time use will affect the life of the lens. The range of lenses available is limited.
The advantages of contact lenses
Contact lenses are worn directly over the eye. Contact lenses are tightly attached to the surface of the eye and can always follow the eye, so you can maintain the same open field of vision like a normal person. You can participate in sports and outdoor activities without worrying about your glasses falling off or breaking. You can even use colored contact lenses to change the color of your eyes. Some girls, in particular, can make their eyes look bigger and more beautiful with the help of various color contacts.
What are prism glasses?
What is a prism? A prism is a solid object with a cross-section along its entire length. If you cut across something, you'll come across a section that's been cut, and that's a cross-section. The upward section is a prism. If you have double vision, you can add a prism prescription to the lens to form prism glasses. It can help keep your eyes focused and greatly improve your vision. In most glasses, prisms are used primarily to change double vision and are useful for image correction. They can aid in position correction.
How to choose a spectacle frame
First of all, we must clarify what are the specific materials of the spectacle frames on the market. At present, the more commonly used glasses frame materials are sheet material, aluminum-magnesium alloy, natural wood, and bamboo materials. Of course, there are other materials such as titanium, TR90, and ULTEM.
Secondly, we have to make it clear that the texture brought by each different material is different, and each has its own advantages. For example, plastic glasses frames are made of sheet materials, which are characterized by easy processing and relatively lightweight. They are generally not easy to deform at room temperature. And the spectacle frame made of metal material is relatively strong, light, and beautiful. Therefore, to learn the advantages and disadvantages of each type of spectacle frame, we can meet our different needs according to each different material.
Price positioning
In terms of positioning, it should conform to students' purchasing behavior, that is, the middle and low-grade products are mainly used, and the appearance requirements are stylish and novel. In addition, you can be properly supplemented with a small number of high-end products, because your market is not only the school but many residents around.
How much do a pure titanium eyeglass frame cost?
For the plastic frame, without a fixed metal rod in the middle, the retail price of the exclusive store is 30 dollars or so. Resin-coated metal frames are inexpensive, 35 to 85 dollars in the store. Because pure titanium is more difficult to make, and the material is more expensive, the frame price often starts from 50 dollars. For example, the ordinary Seiko pure titanium eyeglass frame is about 85 dollars. In Europe and the United States and other developed countries, titanium spectacle frames are popular as a kind of high-grade decoration and fashion. In the past two years, the domestic began to be popular little by little. Titanium spectacle frame belongs to high-grade consumer goods, and the price is usually above 50 dollars.
