How long will the titanium frame last?
Titanium and titanium alloys are often used to make the most durable frames. Their strength is comparable to that of stainless steel. Medical facilities use titanium to make medical implants such as heart valves, showing just how durable the metal can be in extreme environments. Look at the maintenance between quality and use. Good glasses electroplating after three processes, the first is in the glasses or pure raw materials, plating a layer of an adhesion layer, used to attach the plating color layer. The second is the electroplating color layer. The third one is that after the electroplating color layer, another layer of electroplating protection is transparent. The electroplating of glasses through three processes can ensure that the glasses are not easy to lose color and damage in about 5 years. Now the glasses electroplating basically omits the processing of the last layer of the color protective layer, so the service life is about 3 years.
Let the rectangular glasses reflect the fashion aesthetically.
Modern frames are part of fashion and are no longer just medical devices. The person who matches glasses wears glasses, does not hope to expose their shortcomings, but hopes that the glasses can play a decorative role, making up for the shortcomings. The important rule is that according to the face shape, you can choose the appropriate glasses frame to highlight the appearance, to give people a sense of symmetry and balance. For example, people with square faces can wear circular frames and break feelings of edges, and the square frames can add the angular sense of a round face.
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.
Are rimless glasses more expensive than full-frame glasses?
In terms of brand pricing, there are several kinds of prices. For example, the cost of production should be considered. In reality, we ignore the cost of designing products by designers, the cost of workers' wages, and the cost of instruments invested in the early stage. The rimless glasses price is determined according to the material, so if you choose the material of relatively good, the price will be more expensive. In general, the eyeglasses frames are from about 50 yuan to hundreds of yuan. Of course, sometimes the price of rimless glasses is about thousands of yuan. It all depends on the material and lens. You can choose according to your own financial conditions.
What Are Pinhole Glasses?
Pinhole glasses, also called stenopeic glasses, are plastic eyewear with hundreds of pinhole-sized perforations in place of lenses. Pinhole glasses are mostly used to improve refractive errors in the eye because they shield the eye from indirect rays of light which can distort vision. This would decrease the blur circle on the back of the retina.
How to choose blue light blocking glasses?
Nowadays, electronic products such as mobile phones and computers have become indispensable tools in our lives. While these high-tech products bring us convenience and fun, they also bring symptoms such as eye fatigue and myopia. Subsequently, blue light blocking glasses have also received everyone's attention. Anti-blue glasses are only suitable for people who use electronic products for a long time, not for people who are visually fatigued. Exposure to such unnaturally strong blue light for a long time every day, especially for teenagers and children, needs to pay more attention to the prevention of blue light. So, how to choose suitable blue light blocking glasses for kids?
Anti-blue light is necessary, but not all blue light can be filtered out, because blue light will interfere with the body's melatonin secretion after being over-filtered, thereby affecting sleep. Therefore, when choosing blue light blocking glasses, you should choose appropriately according to your own eyes.
For how to choose anti-blue glasses, consumers can distinguish from the color of the lenses. Generally speaking, a lens with a yellow color will have the effect of blocking blue light. But too dark lenses will affect the contrast sensitivity. Therefore, it is recommended that consumers choose moderately. In addition, consumers should also pay attention to whether the glasses products (lenses, frames) have conformity marks, etc. It is best to choose professional and well-known glasses shops to match glasses.
