Advantages of progressive lenses
1. The appearance of the lens is like a single vision lens, and the dividing line of the degree change cannot be seen. Not only is the appearance beautiful, but more importantly, it protects the age privacy of the wearer. There is no need to worry about leaking the age secret due to wearing glasses.(https://www.koalaeye.com/collections/progressive-glasses)
2. Since the change of lens power is gradual, there will be no image jump. It is comfortable to wear and easy to adapt.
3. Because the degree is gradual, the replacement of the adjustment effect is gradually increased according to the shortening of the short distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue.
4. Clear vision can be obtained at all distances in the visual range. A pair of glasses meet the use of long-distance, near use, and various distances in between. It is especially good for teachers, doctors, music workers, and computer operators because these people not only need to see far and near objects clearly, but most of the time they also need to be able to see objects at intermediate distances such as blackboards, piano scores, and computer screens. This is not possible with lenses other than progressive lenses.
5. At present, both internal and external ophthalmologists agree that young people should wear low-degree convex lenses when reading and writing to reduce near-use adjustment, thereby alleviating or preventing the occurrence and development of myopia. This gives the progressive multifocal lens a new meaning and mission. Physiology found that excessive use of the eyeball adjustment function can form 'accommodative spasm' or pseudo myopia. Continued development can produce longitudinal eye axis elongation and induce 'true myopia' or axial myopia. The external luminosity of the progressive lens can be artificially added to the progressive luminosity. The upper is used for looking far, and the below is used for looking near, which makes the eyeball relax and over-adjust. The ever-changing luminosity of the lens replaces the 'accommodative power' that should have been activated, blocking the vicious circle of adjusting the eye axis elongation, making the eye not easy to fatigue, and slowing the development of myopia.
What can I do if the rimless glasses frame is broken?
It depends on the material of the frames. If it is a metal frame, the welding effect of 50 yuan is not worth looking forward to, because the high temperature will burn the welding point and the surrounding color. The electroplating will be destroyed, and it is difficult to accept the appearance. If the metal material is alloyed copper, it will quickly corrode and produce patina. If your frame is broken in a temple, you can fix it yourself with 502 glue or duct tape, but the look will definitely be affected. Or you can go to the optician shop to change the temple. But if all the temples are broken, it's impossible to repair.
The safety role of glasses
Labor protection glasses can help professionals to prevent accidental injuries while working. The main role is to protect the eyes and face from ultraviolet, infrared, and microwave electromagnetic radiation, dust, metal and sand debris, and chemical solution sputtering damage. Many young people like to play computer games, so the eyes are easy for to occur myopia, but radiation glasses can reduce radiation. Chemical solution protection glasses are mainly used to protect eyes from chemical damage caused by irritating or corrosive solutions.
Where did the glasses emoji come from?
The glasses emoji was approved as part of Unicode 6.0 under the name Glasses in 2010 and was added to Emoji 1.0 in 2015. Unlike the bespectacled 'nerd face', which is often used to suggest a cool sense of fashion. Just clicking on a few posts with the emoji is enough to make a person want to follow the eyeglasses fashion trend.
Choose a good frame material
Each pair of glasses has its own characteristics and highlights. The frame itself is an ornament, playing the role of beautification. Today's plate spectacle frames are particularly popular with all kinds of people. Work is complicated and delicate, and design is diverse. Importantly, color and luster are good, not allergic. And it doesn't fade. It is also a high-grade frame. Both the grade and the design are very advantageous. Many brand glasses are made of plates. Some are made of high-grade plates. The appearance is beautiful and stylish.
Difference Between Driving Glasses And Night Vision Goggles
The use of driving glasses and night vision glasses is different. When sunlight is projected on the road or water, it directly stimulates the eyes, making them feel dizzy, tired, and unable to see for a long time. Especially when you are driving a car, doing outdoor entertainment activities, it will not only affect our work and entertainment mood, and even affect our judgment of the image and cause danger. The polarized driving glasses can be used during driving, fishing, skiing, rain, etc. when there is a strong reflection of strong light. Night vision goggles are usually used at night and have great applications in transportation, the military, and other fields. A large amount of night vision equipment has been used as a winning strategy to dominate night combat. Combining night vision technology with weapons and equipment will greatly improve the effectiveness of weapons and equipment in getting information, conducting strikes, commanding troops, and coordinating operations at night and in bad weather.
Benefits of glasses with nose pads
Glasses with nose pads reduce the load on the bridge of the nose and make them more comfortable to wear. In addition, glasses with nose pads can have a non-slip effect, especially for people with a low nose bridge. It will be much more comfortable to choose glasses with nose pads, so there is no need to worry about the trouble of holding the glasses all the time.
