Lunor - Glasses For Men
Many of Lunor's metal frames are made from high-quality titanium, gold, and stainless steel. In addition to the special process of making titanium, all-metal frames are made by hand in a factory in Germany, fully reflecting the craftsmanship and thought behind the production of the brand. The texture and professional demeanor of the glasses are strong. The brand is very good at combining classical and modern. What we can see is that the nose pad and the frames are made of pure titanium, so there's no allergic effect.
What Should You Do If Your Glasses Are Broken?
A professional eyewear repair shop ensures accurate repair. Fixing metal frames requires special welding equipment and expertise, and you could injure yourself or your frame if you try to weld them by yourself. A professional can make sure your glasses are accurately repaired. If you're not precise enough in repairing a damaged frame, you may be able to see through a crooked pair of glasses, which can damage your vision. Plastic frames are easier to fix than metal frames. Fixing the frames by yourself poses a greater risk than having them repaired by a professional.
Is there any relation between lens refractive index and lens definition?
First of all, in reality, from the point of view of the immediate situation, there seems to be no correlation. The refractive index is mainly related to the speed of light transmission into the lens. High refractive index lenses can be made thinner, lighter, and the technology required to do this is more sophisticated, so high refractive index lenses are more expensive. But does a high refractive index make the lens clearer? The higher the refractive index of the lens, the lower the Abbe number. The Abbe number is a very important parameter we use to measure the sharpness of the lens, which means that if the refractive index of the lens is high, that is to say, the sharpness of the lens is lower. If you have higher degrees, you can prioritize thinness and choose a lens with a higher refractive index, but don't overdo it.
Driving Glasses - Conant
Conant is a well-known lens brand and a famous trademark in Shanghai. It is a listed company, a high-tech enterprise in Shanghai. It is one of the largest suppliers of Chinese glasses in the world market. And it is an early enterprise in the field of resin lens production in China.
What characteristics do children's glasses have?
The lens degrees need to change with the degrees of the eye. Because children are still in the process of growth and development, especially preschool children and adolescent children. Preschool is the key period of visual development, and farsightedness is slowly reduced. The eyeball development is close to an adult. Adolescence is the second peak of eyeball development, and myopia is most in this stage and little by little deepens, stopping at the end of adolescence.
Choose polarizer for fishing
It is best to choose a polarized lens for fishing to filter out the reflections on the water surface. If it is myopia, it is best to choose polarized sunglasses with myopia function according to your own eye conditions. Generally, shops in the glasses city can customize such glasses. There are also special fishing glasses that can eliminate the scaly light on the water surface so that the angler can see the fish hooked.
What are the causes of lens damage?
When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.
In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.
