In recent years, the glasses chain has developed fastly, especially in large and medium-sized cities. The professional glasses stores use their own technical force, progressive optometry equipment, and years of store reputation, which drives the whole industry to improve the quality of products. Nowadays, with the development and expansion of the eyewear industry, eyewear chain stores have become the main force of eyewear product sales in China and even the world. Moreover, tens of thousands of people are directly or indirectly engaged in the operation or management of eyewear chains or related to them.

What should drivers notice when wearing polarized glasses?
Many drivers like to wear polarized lenses. Indeed, the polarized lens can reduce strong light, eliminate glare, so that the line of sight is natural and soft, but the polarized lens is more suitable for fishing, skiing, and other large areas of the reflective environment. Drivers sometimes have to face the tunnel and another dark scene, the polarized lens is easy to make people suddenly feel dark at the moment. In addition, polarized lenses can make LCD screens and LED traffic lights dim. Therefore, when choosing polarizers, it is best to choose good quality optics, and when going through the tunnel, it is best to take off your glasses ahead of time and blink a lot. Before wearing the driver polarizing lens, try it on and observe whether the polarizing film of the lens is smooth. If the polarizing film is uneven, there will be inflow in the imaging, which may lead to visual fatigue and migraine.
Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses.
The main observation area of the progressive lens is a far distance, the smaller area at the bottom of the lens is used for myopia, and the middle area in the middle is smaller. Standard progressive glasses are very suitable for general purpose glasses, focusing on hyperopia activities (such as driving and walking) and sufficient area in the lenses for nearsighted activities (such as reading and computer use). The left and right sides or 'convex corners' of the lens are deliberately blurred to achieve an invisible design. The clearest line of sight in the gradual process is from the center to the top of the lens.
Optometry for prescription glasses
The key prerequisite for proper glasses is accurate optometry. In foreign countries, professional optometrists are generally required to be qualified to issue prescriptions for optometry. However, this is not very standardized in China. Many optometrists have only been trained for a short period of time and do not have the basic knowledge of ophthalmology. For some complex situations, they may not give a proper prescription for glasses. Therefore, optometry should choose a qualified institution. If you are adolescents, people with high myopia, people with anisometropia, etc., you may need to dilate your pupils for optometry. It is best to go to the optometry center of the hospital for optometry.
What Are Bifocals?
There are several kinds of lenses available in the market. Now, there is a kind of lenses by stacking two different kinds of lenses together and they are called a bifocal lens. Bifocal lenses are lenses with lines separating two different prescriptions. There is a presence of a distance lens at the top and the lower part has a lens that can be used to view the objects placed nearby.
Bifocal lenses are designed for people who have presbyopia, a condition in which the person can’t see the nearby placed objects. Presbyopia is an age-related condition, often occurred when people are over 40 and people often have blurred vision.
At the same time, there are different types of bifocal lenses present and they provide the same user which is the lower part of the lens is used to view the nearby objects or to do work related to reading and writing while the upper part of the lens is used to view the objects placed at a faraway distance or to do an activity like driving.
So, in the following section, we will show you the different types of bifocal lenses.
