Nowadays, more and more people are wearing glasses, because the quality of life is improving, the requirements for lenses are getting higher and higher, traditional monofocal lenses can no longer meet the needs of customers, progressive lenses are gradually becoming popular and becoming the first choice for vision correction, such as France, Germany, USA, Japan, Asia Pacific and Eastern Europe, etc., the wearing of progressive multifocal glasses is showing an increasing trend every year, more and more optometrists and opticians are using progressive lenses as an important option for vision correction.
The traditional progressive multifocal, which satisfies the need for a pair of glasses that can see far and near at the same time, has some problems due to technical limitations in the production process, as there are blind spots on both sides of the lens, which restrict the effective field of vision and make it difficult to adapt.
Our lenses have been reformed to solve the problems caused by the traditional progressive multifocal, improving and optimising the shortcomings of the traditional progressive multifocal, eliminating the blind spots and the full channel progression, with a progressive direction from far to near, in line with the optical principle, making the field of vision wider, clearer, more comfortable and easier to adapt.
Semi-finished processing tips.
The semi-finished products are underglazed (near light area) and can be ground on the concave side of the lens according to the optometry data. The following are the recommendations for the selection of the lower light.
1. according to the degree of myopia (schoolchildren or adolescents): up to -300°, underglazing +100°; up to -450°, underglazing +150°; up to -600°, underglazing +200°.
2. For reference according to age: ~40 years +100 degrees, -45 years +150 degrees, ~50 years +200 degrees, ~60 years +250 degrees.
3. According to individual needs.
1. anti-blue light, progressive multifocal lenses without blind spots.
2. Semi-finished products, also known as ADD, also known as lower plus (which is part of the near-light area of the lens), whose prescription is formed on the convex side and is externally progressive.
3. The concave side of the lens, which can be ground according to the desired distance.
The lower light zone of our lenses is curved and its progression is from the periphery of the arc towards the inner progression, with a progression that can be matched to the distance, from far to near. This solves the problem of blind spots and at the same time conforms to the optical principle.
The company, formerly known as Guanbai Donghai (Tianjin) Optical Technology Co., LTD., was established in 2012 in Tianjin, with registered capital of 5 million US dollars, covering an area of 3,500 pyeong meters and 50 to 70 employees, mainly produces general optical lenses and functional lenses, including single-focus lenses, multi-focus lenses, reading glasses and Trivex explosion-proof lenses... In 2018, it moved to Chongqing and settled in Fengjie County Ecological Industrial Park, and changed its name to "Chongqing Yuanzhongjin Optical Technology Co., LTD.". In response to the market demand, it has actively transformed itself, mainly engaged in the research and development and production of functional lenses without blind area, special lenses for students, anti-fatigue lenses, three-in-one lenses and intelligent reading glasses.
With the improvement of the quality of life, the requirements for glasses are also rising. Single-focus lenses can no longer meet the wearer's requirements for quality, and there are progressive multi-focus lenses. The advent of progressive multi-focal lens is the improvement and breakthrough of single focal lens. One set of glasses can meet the needs of different degrees of seeing far and near. However, due to the limited technology, there are some problems, the blind area on the lens and the limit of sight area, affecting the wearer's comfort and adaptation of the trouble, its field of vision is also limited.
Our company has found a way to solve these problems, and put great effort into the development and research of the technology. We can introduce the healthiest and most in line with the optical principle. Finally, we have successfully developed the progressive multifocal lens without blind area, without blind area design, so that the wearers are more comfortable and easier to adapt, and at the same time, the field of vision is wider. To protect your eyesight and strive to improve and improve the existing lens "pain points", to create a more perfect lens, to complete the design of the leading, leading technology of the enterprise goal.
The main product of our company is multifunctional lens without blind area, which has the following 6 features and functions, all of which are pioneering in the function and technology of glasses, leading the industry:
1. Students special lens: effectively relax the ciliary muscle, slow the rapid deepening of myopia vision.
2. Anti-fatigue lens: can avoid office workers watching computer screen for a long time, and cause eye fatigue.
3. Three and one lens: to solve the problems of the old people with myopia and presbyopia, see far, see, see are clear, a pay can meet.
4. Smart reading glasses: silver hair's favorite, see far and near are clear, glasses do not need to take off.
5. No blind area design, improve the wearer's comfort, easier to adapt, wider vision.
6. Appropriate distance, appropriate luminosity, full channel design, in line with the optical principle, can protect the eyes more effectively.
