In the realm of eyewear, manufacturers have increasingly shifted towards the use of polycarbonate and other plastic materials for lenses due to their lightweight and shatter-resistant properties. However, several consumers still prefer glass lenses for their superior scratch resistance, clarity, and optical precision.
When it comes to sunglasses, the lenses play a vital role in providing clarity, protection, and style. While many sunglasses feature lenses made of various materials, one company stands out for its expertise in manufacturing sunglasses with glass lenses. Let's take a closer look at Jiangsu Maat Optical Technology Co., Ltd, a renowned manufacturer with 20 years of experience in the industry.
Jiangsu Maat Optical Technology Co., Ltd has 20 years of experience in manufacturing resin photochromic lenses. The factory has more than 500 employees and exports the lenses to 48 countries and regions around the world. The factory covers an area of 60,000 square meters, and the annual production of lenses is 20,000,000. Tens of millions of dollars. We produce all kinds of photochromic lenses, finished and semi-finished, in grey/brown/blue/purple/pink/green colors.
Sunglasses have transformed from practical eye protection into a fashion staple. This section explores the origins of glass lenses and how sunglasses evolved.
The use of glass for eye protection can be traced back to the prehistoric era, but the incorporation of glass lenses into frames designed specifically for sun protection likely occurred much later. Early sunglasses with flat glass lenses aimed to reduce glare but did not offer the UV protection that modern glasses provide. Various cultures adopted the concept, with reported use by judges in Chinese courts to conceal their emotions during the 12th century.
Sunglass design has seen substantial changes from its inception to the modern day. In the 18th century, James Ayscough popularized spectacles with tinted lenses, believing they could correct specific vision impairments.
The 20th century marked a significant evolution, with the development of sunglasses as a fashion accessory.
Celebrities and public figures played pivotal roles in this transformation, often being seen wearing iconic styles that defined eras. As technology advanced, so did the functionality and style of sunglasses, leading to various frame materials and lens types, including the enduring popularity of glass lenses for their clarity and scratch resistance.
With two decades of experience, Maat Optical has established itself as a trusted manufacturer of high-quality lenses. The company boasts a workforce of over 500 employees and exports lenses to 48 countries and regions worldwide. This global presence is a testament to their commitment to delivering exceptional products to customers around the globe.
Maat currently adopts two kinds of production processes to meet the needs of different consumer groups.
In-mass photochromic originally was developed by Corning in the 1960s and applied to glass materials, nowadays it is widely used in resin lens production. The principle is mixing photochromic dyes with lens monomer, the biggest advantage is a stable photochromic performance at a lower price, the bands are only mid-index available, and lower responsive speed(both darkening and fading time).
CB layer coating photochromic, also named spin-photo, is considered to be the most advanced photochromic lens production technology nowadays.
Maat Optical takes pride in offering a diverse range of glass lenses to cater to various preferences. Their collection includes photochromic lenses in grey, brown, blue, purple, pink, and green colors. Whether customers seek finished lenses or semi-finished options, Maat Optical provides choices to suit different eyewear designs and styles.
Commitment to Quality and Compliance
Quality is a top priority for Maat Optical. They adhere to major global quality standards such as CE, FDA, and ISO, ensuring that their products meet stringent quality requirements. Additionally, the company emphasizes environmental sustainability and occupational health and safety, holding certifications in these areas as well.
Investment in Research and Development
Recognizing the significance of talent in driving innovation, Maat Optical prioritizes the development of its R&D team. Comprised of industry leaders, professors, experienced engineers, and experts with years of experience in the lens industry, the R&D team fuels the company's continuous improvement and product advancements.
Photochromic Dyes
Photochromic lenses remain clear indoors, while get dark outdoors when exposed to UV light present in sunlight. The major factor of the magic is the photochromic dyes in the lens or on the surface of the lens. After decades of R&D and improvement, Maat has made breakthrough achievements in its self-developed and improved dyes:
●Faster responsiveness
●Darkness up to CAT-3 level
●Stability and consistency in all optional colors
●Long-service life
The lens monomer(major material) is supplied by worldwide brand companies, PPG, Mitsui, KOC, and so on.
Maat does not produce all the substrate lenses ourselves, we also use a self-developed process to apply patented photochromic dyes or other photochromic materials to our partner’s clear substrate lenses.
Excellent Transition Speed
Generally, a photochromic lens gets very dark in 30 seconds and fades back to acceptable clarity in 2 minutes. Maat’s self-developed super fast and dark photochromic(Maatlite RapidyTM) lens improved the transition speed by 20%(darkening speed 18.5% faster, fading speed 26% faster)compared with regular In-mass photochromic lenses.
By introducing the latest generation of CB layer coating dyes, the Maat CB2 photochromic lens improved its transition speed without sacrificing any photochromic properties. It’s a breakthrough product in all dimensions.
