CR-39 Sun lenses are lightweight, high-clarity lenses widely used in prescription sunglasses and non-prescription solar eyewear. Key features include:
· Excellent Optical Clarity – High Abbe value (≈58) with minimal chromatic aberration.
· Lightweight – About half the weight of glass, enhancing wearing comfort.
· Good UV Protection – Naturally blocks up to 100% of UVB and ~90% of UVA; can be fully UV-protective with added coatings.
· Scratch-Resistant – Softer than glass, but hard coating is often applied for durability.
· Chemical Resistance – Resistant to most solvents and environmental degradation.

1.49 Polarized Lenses Made from lightweight, impact-resistant optical resin CR-39 with an embedded polarizing film. They effectively block blinding glare reflected off flat surfaces like water, roads, or snow, enhancing visual clarity and contrast. Key features: 100% UV400 protection, excellent optical clarity, shatter resistance, and up to 50% lighter than glass. Ideal for driving, fishing, skiing, and daily sunglasses.
1.60 Tough Blue cut Lens made with ultra-flexible materials that significantly reduce breakage risks, meeting high safety standards for sports and daily activities. With clear Vision Technology, maintains true color perception while minimizing glare—unlike yellow-tinted alternatives. Meanwhile blocks a significant portion (typically 30%-40%) of high-energy blue light emitted from digital screens, helping reduce digital eye strain and supporting healthier sleep cycles.
1.74 Blue cut lens is high-index, ultra-thin lenses designed primarily for people with strong prescriptions (high myopia), improving appearance. Enhances contrast and may reduce glare, leading to a more comfortable viewing experience. The key feature is the blue light filtering technology. It selectively blocks a portion of harmful high-energy blue light emitted from digital screens (computers, phones, tablets) and LED lighting, while allowing beneficial light to pass through.
1.67 Blue cut lens is premium, high-index optical lenses designed for both vision correction and digital eye protection. the lenses are significantly thinner and lighter than standard lenses, especially for stronger prescriptions. This improves aesthetics and comfort. They feature a special filter that blocks a portion of High-Energy Visible (HEV) blue light emitted from digital screens (computers, phones, tablets), LED lights, and the sun.
PC (polycarbonate) blue light blocking lenses are durable, lightweight eyewear lenses designed to filter out harmful blue light emitted from digital screens and artificial lighting. They help reduce eye strain, improve visual comfort, and support better sleep patterns by minimizing blue light exposure. Thanks to their impact-resistant material, these lenses also offer enhanced safety for active lifestyles. Ideal for daily computer use and screen-heavy environments.
1.60 Blue cut lens is mid-index material that is thinner and lighter than standard lenses (1.50 index), providing comfortable wear and better aesthetics for a wide range of prescriptions. The lens features a special coating or material that filters a portion of High-Energy Visible (HEV) blue light, primarily from digital screens (phones, computers) and LED lighting. It helps reduce potential digital eye strain, discomfort.
1.56 Blue cut photochromic progressive lenses are multifunctional eyewear that automatically adjust tint indoors and outdoors. They darken in sunlight to reduce glare and UV exposure, while filtering harmful blue light from screens and artificial lighting indoors. Designed for presbyopia, they provide seamless vision correction for distance, intermediate, and near tasks, offering convenience, eye protection, and all-in-one visual support."
1.56 Blue cut Progressive Lens combine two key features: progressive multifocal technology and blue light filtration.
· Progressive design – Seamless transition from distance correction at the top to near vision at the bottom, with no visible lines. Ideal for presbyopes.
· Blue light protection – A specialized coating or embedded filter reduces exposure to high-energy visible (HEV) blue light (380–450 nm) emitted by digital screens, LED lights, and sunlight.
· Progressive design – Seamless transition from distance correction at the top to near vision at the bottom, with no visible lines. Ideal for presbyopes.
· Blue light protection – A specialized coating or embedded filter reduces exposure to high-energy visible (HEV) blue light (380–450 nm) emitted by digital screens, LED lights, and sunlight.
1.56 Photochromic progressive lenses combine two advanced optical technologies: progressive addition for seamless vision correction at all distances, and photochromic properties for automatic light adaptation.
Key Features:
· Seamless Multifocal Vision: Unlike traditional bifocals or trifocals, these lenses offer a smooth transition from distance (top) to near vision (bottom) without visible lines.
· Automatic Tint Adjustment: The lenses darken when exposed to UV light outdoors, turning into sunglasses, and fade back to clear indoors.
· 100% UV Protection: They block harmful UVA and UVB rays when activated.
· Convenience: One pair of glasses works for reading, computer work, driving (though some may activate less behind a windshield), and outdoor activities.

A Progressive Addition Lens (PAL), is an advanced type of eyeglass lens designed to provide a seamless correction for multiple vision distances. Unlike traditional bifocals or trifocals with visible lines, PALs feature a smooth, gradual transition of lens power from distance correction at the top to near correction at the bottom, with intermediate vision in between.
Main Benefits:
· Convenience: Ideal for individuals with presbyopia who need correction for both far and near vision.
· Cosmetic Appeal: Appears like a regular single-vision lens.
· Adaptability: Supports daily activities ranging from driving and reading to using digital devices.

1.56 Photochromic bifocal lenses are dual-purpose eyeglass lenses that combine two key features:
1. Automatic Light Adjustment: They contain light-sensitive molecules that darken automatically when exposed to UV sunlight (becoming tinted sunglasses) and clear up indoors or at night.
2. Two Vision Corrections: They feature a distinct bifocal segment (usually a visible line or a seamless progressive zone) to provide clear vision for both distance (top portion) and near tasks like reading (bottom portion).
In short: They are "all-in-one" lenses that act as both regular glasses and sunglasses while correcting both distance and near vision.
