Progressive lenses, also known as multifocal lenses, have revolutionized the eyewear industry by offering a seamless solution for people who require correction for both near and distant vision. Unlike bifocal or trifocal lenses, which have visible lines separating different lens powers, progressive lenses provide a gradual transition between multiple focal points. This article delves into the mechanics of progressive lenses, their benefits, and how they compare to other lens options, supported by data and industry insights. Additionally, we will highlight how Maat Optical's innovative photochromic lenses, backed by 20 years of expertise, are an excellent choice for wholesalers seeking high-quality products. Eye Health and Progressive Lenses: What the Research Shows Clinical studies have shown that progressive lenses can significantly alleviate symptoms of digital eye strain, with a reported 32% reduction compared to single-vision lenses. Additionally, these lenses help ensure that the eye remains focused correctly at all distances, reducing the risk of conditions such as myopia and hyperopia. The Sophisticated Mechanics Behind Progressive Lenses Progressive lenses are designed to correct myopia and hyperopia, a condition that affects the eye's ability to focus on close objects. This is achieved by integrating a gradual shift in lens power from the top to the bottom of the lens. The upper part of the lens is optimized for distance vision, the middle section is for intermediate distances, such as computer work, and the lower portion is for near vision, like reading. Key Components: Distance Vision Zone: Located at the top of the lens, this area is tailored for viewing objects at a distance, such as when driving or walking. Intermediate Vision Zone: The middle section is designed for mid-range tasks, like computer work or viewing a dashboard. Near Vision Zone: The bottom part of the lens provides the necessary correction for close-up tasks, such as reading or sewing. The Science Behind the Smooth Transition: How Progressive Lenses Work The true brilliance of progressive lenses lies in their ability to offer a seamless visual experience. This is achieved through advanced lens design techniques that gradually alter the curvature of the lens surface. Unlike bifocals, where the division between different focal powers is stark, progressive lenses provide a continuous gradient that closely mimics the natural way our eyes adjust focus. The Role of Digital Surfacing Technology Modern progressive lenses are often crafted using digital surfacing technology, a process that allows for precise customization based on the wearer’s prescription and individual visual needs. This high-tech approach ensures that each lens is tailored to provide the most comfortable and natural visual experience, reducing the need for head movement and minimizing eye strain. Supporting Data and Industry Insights A study in the Journal of Optometry revealed that 87% of users experienced improved visual comfort and acuity with progressive lenses compared to bifocals. Moreover, research published in Ophthalmic & Physiological Optics highlighted the reduced need for head adjustments, making progressive lenses a preferred choice for those seeking a natural and uninterrupted field of vision. Mechanism of Myopia Myopia Pathogenesis Model: (A) Myopic visual signal stimulation leads to the thinning of the choroid and sclera. (B) Myopic visual signal stimulation causes a reduction in choroidal blood flow, resulting in decreased oxygen and nutrient supply to the sclera. Scleral fibroblasts sense this change in the microenvironment, leading to the upregulation of HIF-1α expression. This induces fibroblast-to-myofibroblast transdifferentiation, inhibits collagen synthesis, causes scleral thinning, and ultimately leads to the elongation of the axial length, resulting in the development of myopia. Versatility Across Various Activities Whether for reading, working at a computer, or engaging in outdoor activities, progressive lenses are versatile enough to meet a wide range of visual demands. Their ability to provide clear vision at multiple distances makes them suitable for almost any situation, offering unparalleled convenience for the wearer. Here are our two different series of progressive lenses, each suited for different scenarios： Premium-Design: Progressive Lens for Relaxing Different eyeglasses serve different purposes, and no single lens is ideal for all activities. If you spend significant time on specific tasks like reading, desk work, or computer use, task-specific glasses might be necessary. Mild add lenses, such as those in Maat Optical's Relaxing series, are designed to replace single-vision lenses as a primary option, especially for those aged 18-40 who experience eye strain. The Relaxing series offers enhanced comfort and a slight power boost in the lower portion of the lens to ease eye strain during close-up tasks. These lenses provide: A slight power boost in the lower portion of the lens to ease eye strain during close-up tasks.

In most cases, photochromic lenses are a boon for eye health. The only exceptions are poorly made lenses that fail to block UV light effectively, potentially causing harm. Let’s explore why this happens by understanding how photochromic lenses work. Photochromic lenses change color because they contain UV-sensitive materials like silver halide and copper oxide. When exposed to UV light, silver halide breaks down into tiny black particles, darkening the lens. This process is similar to how photographic film works, but it's reversible. When UV light is no longer present, the particles recombine, and the lenses become clear again. Despite some concerns about dilated pupils allowing more UV light in, choosing high-quality, standard-compliant photochromic lenses alleviates these worries. Let’s break down the impact of light on our eyes and how these lenses can help. The Impact of Light on Our Eyes 1. Light Sensitivity and Strong Light Exposure Our eyes constantly adapt to changing light conditions throughout the day. Both natural sunlight and artificial sources like LED lights, flashlights, and screens can cause light sensitivity. In bright light, our eyes squint and pupils contract to reduce light intake. Prolonged exposure to intense light can lead to eye strain, dryness, tearing, muscle spasms, swelling, and dizziness. 2. Harmful Light: UV and Blue Light Exposure UV light can damage various parts of the eye, including the conjunctiva, cornea, lens, and retina, leading to conditions like pterygium, keratitis, cataracts, macular degeneration, and even ocular melanoma. Everyday sources like LED lights and tanning lamps emit significant amounts of blue light, which also impacts eye health. Why UV Light Damages Eyes The cornea contains corneal epithelial cells, and the principle of UV sterilization is to damage the cell nucleus. Therefore, similarly, UV rays can also damage the nuclei of corneal epithelial cells, leading to large-scale shedding of the corneal epithelium. This exposes the nerve endings of the upper and lower epithelium, resulting in severe photophobia and tearing, and sometimes a strong foreign body sensation. To elaborate further, UV rays act on the water molecules in epithelial cells, causing dissociation of these molecules, which generates a large number of free radicals. These free radicals can attack the cells in various ways, leading to cell death and shedding caused by UV exposure. These symptoms peak about 12 hours later. This means that often when you look directly at the sun in summer or are exposed to the sun for a long time, you may only feel slight discomfort in your eyes at that moment. However, in the following week or even longer, you are likely to experience eye discomfort, and this is merely the acute reaction, known as photokeratitis. UV light’s cell-damaging effects can not only severely impact the cornea, disrupting epithelial cells and causing corneal erosion. This exposure can result in severe photophobia, tearing, and a sensation of foreign bodies in the eye. Chronic UV damage is cumulative and irreversible, contributing to cataracts and other eye problems. High-quality photochromic lenses can mitigate these risks by effectively blocking UV radiation. Misconceptions About Photochromic Lenses Some believe photochromic lenses are harmful because substandard coatings might not block UV rays adequately. Also, sudden removal of these lenses in bright light can disrupt the eye’s adjustment process, leading to photokeratitis. However, using high-quality photochromic lenses minimizes these risks and proves beneficial for overall eye health. Solutions for Light-Induced Eye Strain For those with vision impairments, traditional sunglasses can be cumbersome and may not match prescription needs well. Photochromic lenses are a convenient solution, adapting to varying light conditions and providing comprehensive UV protection. Why Choose Photochromic Lenses? 1. Daily Convenience: They seamlessly adapt to changing light conditions. 2. Comprehensive Protection: Blocking over 99% of UVA and UVB rays and harmful blue light. 3. Versatility: Suitable for various environments and activities. Among the top choices are MaatOptical’s photochromic lenses, known for their advanced technology and superior UV protection. MaatOptical Photochromic Lenses MaatOptical employs two production processes to cater to different needs: in-mass photochromic and CB layer coating. The in-mass method, developed in the 1960s, offers stable performance at a lower price. The CB layer coating, or spin-photo method, is a more advanced technology, providing faster response times and better performance. Production Process 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. Advantages: faster color changing speeding and fading speed, more optional indexes and flexible function selection. Disadvantage: higher price. 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: 1. Faster responsiveness 2. Darkness up to CAT-3 level 3. Stability and consistency in all optional colors 4. Long-service life Lens Substrate 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. UV Protection Not only do Photochromic lenses react to UV light—but they also protect your eyes from it! It could fully block UVA and UVB rays, reducing the risks of UV-related cataracts and other eye diseases. Blue Light Filter A blue light filter is optional in most of our products, we now supply photochromic lenses with two levels of blue light filter, UV410 and UV420.UV410 blue light filter is designed for light office work, an average of 3-4 hours per day in front of the computer.UV420 suits people who work with computers all day long or have higher blue light protection needs. 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.

How Direct Light Affects Health? Direct light can have both positive and negative effects on your eyes. On one hand, it provides clear visibility, making tasks easier and reducing eye strain. However, prolonged exposure to intense direct light, especially from sources like the sun or bright lamps, can lead to discomfort, glare, and even temporary vision impairment. It's like squinting in the sun—uncomfortable, right? Over time, this can contribute to eye fatigue and other issues. This can be prevented by using UV protection glasses. UV Radiation UV (Ultraviolet) radiation, often from the sun, is an invisible form of light that can be both beneficial and harmful. On the positive side, it helps our bodies produce Vitamin D, crucial for bone health. However, excessive exposure can damage skin and eyes, causing cataracts, macular degeneration, photokeratitis, skin cancer, and more. How UV Radiation Affects Health Cataracts A common disorder of the eyes that causes the lens to grow hazy and impair vision is called a cataract. Although age is the most common factor, other factors include heredity, smoking, and UV exposure. Blurred vision, sensitivity to intense light, and trouble seeing at night are among the symptoms. Fortunately, cataract surgery, involving the removal of the cloudy lens and its substitution with an artificial one, boasts a high success rate. Timely detection via regular eye check-ups is essential for swift intervention to regain clear vision. Neglecting cataracts, on the other hand, may result in loss of eyesight. Macular Degeneration The macula, the center region of the retina essential for crisp vision, is impacted by the progressive eye disease known as macular degeneration. It frequently happens as people age, leading to a progressive loss of central vision necessary for tasks like driving and reading. Genetics, smoking, and UV exposure all increase the risk. The symptoms include hazy or distorted vision, black patches, and difficulty recognizing faces. While there is no treatment, early detection through frequent eye exams is critical for controlling symptoms and preserving eyesight. Photokeratitis Photokeratitis, often known as "snow blindness," is similar to a sunburn for your eyes and is caused by excessive UV light exposure. It can result from spending too much time in the sun, particularly near snow, water, or sand, or using tanning beds without proper eye protection. Symptoms include eye discomfort, redness, tears, and light sensitivity. Fortunately, it normally goes away on its own after a few days, but it is not enjoyable while it lasts! Skin Cancer Around The Eyes Skin cancer around the eye is a serious concern due to the delicate nature of the skin in this area and its exposure to sunlight. Types of skin cancer that commonly affect the eye area include basal cell carcinoma, squamous cell carcinoma, and melanoma. Risk factors include sun exposure, a history of sunburns, fair skin, and a weakened immune system. Symptoms may include a change in the appearance of the skin, such as a growth, sore, or spot that doesn't heal. Early detection and treatment are vital. Protecting the eyes with sunglasses and sunscreen can help prevent skin cancer around the eyes. Eye Strain and Its Dangers Eye strain, or tired eyes, happens when your eyes get overworked from activities like reading, using digital devices, or driving long distances. How It Affects Health Eye strain, often caused by prolonged screen time or intense focus on tasks, can impact overall health. It leads to symptoms like headaches, blurred vision, dry eyes, and neck and shoulder pain, making daily activities uncomfortable. Persistent eye strain can also contribute to fatigue and decreased productivity. Additionally, eye strain can interfere with sleep patterns, especially if you're exposed to blue light from screens before bedtime, leaving you feeling tired and less focused. Visual Disturbances Extended periods of focusing on screens or close-up tasks can result in eye strain, causing discomfort such as double vision and blurred vision. When your eye muscles are overworked and fatigued, it becomes challenging to maintain proper focus, leading to blurry vision and difficulty perceiving objects sharply. Moreover, strained eye muscles may struggle to coordinate effectively, resulting in double vision, making activities like reading or computer work difficult. To mitigate these problems, taking regular breaks, ensuring comfortable screen brightness, maintaining adequate lighting in your workspace, adjusting your posture, and optimizing the distance between your eyes and the screen is important. Solutions to Protect Eye Health ·Avoid reading in the dark ·Wear a sun hat and other sunshades ·Regular eye exams ·Avoid peak sun hours ·If you are a myopic, hyperopic, or presbyopic --- wear prescribed photochromic lenses Photochromic Lenses, More Than Meets The Eye What are photochromic lenses? Sometimes referred to as transition lenses, they can adjust their tint based on the surrounding lighting conditions. These lenses are made with materials that respond to UV light exposure, leading them to darken outdoors and return to their clear state when indoors, shielding the eyes from UV exposure and glare. Additionally, the convenience of not having to switch between regular eyeglasses and sunglasses is provided by photochromic lenses. Primary Function Block Harmful UV Rays, Providing Convenience For Users Photochromic lenses automatically darken in sunlight, blocking harmful UV rays. These lenses contain molecules that change structure when exposed to UV light, protecting the eyes by absorbing UV radiation. Ideal for outdoor enthusiasts, they offer convenience and eye safety without needing to switch between regular glasses and sunglasses. Reduce Eye Strain, Providing Comfort By adjusting to varying light conditions, photochromic lenses help reduce eye strain. They darken in sunlight and lighten indoors. This light adaptability minimizes glare and squinting, ensuring optimal visibility and comfort for users Blue Light Filtration Photochromic lenses also reduce blue light exposure by filtering it out as they darken in response to sunlight. This helps protect your eyes from digital screens and natural sunlight, reducing eye fatigue and enhancing visual comfort. Fashion Photochromic lenses are fashionable and functional, offering stylish eyewear that adapts to changing light. They come in various designs and tints, complementing any look while providing UV protection and comfort. Perfect for those who want to combine eye health with trendsetting style, these lenses are both practical and chic. Mechanism Behind Color-Changing Lenses UV Light When exposed to ultraviolet (UV) light, photochromic lenses darken. The amount of UV exposure needed to activate these lenses varies depending on certain factors like the lens material and the particular photochromic technology used. Generally, photochromic lenses take about 30-45 seconds of direct UV exposure to start darkening; however, depending on the intensity of UV light, full darkening may take a few minutes. Once indoors or out of direct sunlight, the lenses gradually return to their clear state. It's important to note that photochromic lenses may not darken as effectively in certain situations, like inside a car. Thermal Dependence Photochromic lenses also react to changes in temperature, becoming darker in colder environments and lighter in warmer conditions. This dual mechanism ensures that the lenses adjust to provide comfortable vision in different lighting and temperature settings. The specific temperature range and degree of lens darkening can vary depending on the lens material and technology. Users can enjoy the convenience of adaptive eyewear that responds not only to sunlight but also to temperature fluctuations, providing clear vision and protection throughout the day. Optical Technology Achievements P8 Pro Rapid Photochromic Lens Deeper Discoloration +33% Depth of discoloration, reaching 93.3% Depth after 90 seconds. Fades Faster 73.6% Transmittance after 5 minutes and can be worn continuously for up to 12,000 hours. P8 Pro Rapid Photochromic Color Changing Lens The lens absorbs ultraviolet light, it is also resistant to a few environmental factors such as light, high temperature, oxidation, and stains. P7 Freeform Progressive Inner Surface Lens Reduced shaking and distortion of the side of the lens, allowing the user to perceive a wider field of vision. P7 Progressive Multifocal Color Changing Lens Progressive photometric design reduces the eye rotation angle, reducing the vertical movement of the eye, and making eye rolling more comfortable. CB7 Layer Coat Photochromic Lens Composite Bonding technology (CB) Different materials are selected based on their optical properties, such as refractive index, UV absorption, and impact resistance. The chosen materials are then layered and bonded together, and finally, additional coatings are applied to the lens surface. Benefits ·Enhanced optical performance ·Improved durability ·Customization ·UV and blue light protection Conclusion Photochromic lens and direct light can have a significant impact on users' comfort and eye health, posing both benefits and risks. The UV radiation from direct light, particularly sunlight, can be harmful to your eyes. Long-term exposure to UV radiation, without proper protection, can result in cataracts, macular degeneration, and even skin cancer around the eyes. However, wearing UV-blocking sunglasses can assist to lessen these risks by protecting the eyes from damaging radiation. Photochromic lenses, on the other hand, are meant to change with the lighting conditions. When exposed to UV light, the lenses become dark, providing additional protection against harmful radiation and glare. They provide wearers with convenience by removing the need to switch between ordinary glasses and sunglasses.
