Lens Options

Material option of Lens

Resin Lenses: Include CR-39 resin lenses, which are lightweight, cost-effective, and offer good light transmission; and high-index resin lenses, which have a higher refractive index, making them thinner and more suitable for individuals with high myopia or hyperopia.
Glass Lenses: Available in standard optical glass lenses and high-index glass lenses. The former has high hardness and excellent optical performance but is heavy and fragile, while the latter is thinner and lighter but has higher chromatic dispersion.
PC Lenses (Polycarbonate Lenses): Known for their high impact resistance, lightweight design, and excellent UV protection. However, they are difficult to process, have poorer chromatic dispersion control, and are relatively expensive. They are commonly used in sports and safety eyewear.
Nylon Lenses: Highly flexible, impact-resistant, and lightweight. However, they have lower light transmittance and are prone to scratches, making them mainly used for sports eyewear.
Crystal Lenses: Scratch-resistant with a low thermal expansion coefficient. However, they are expensive, difficult to manufacture, and have lower light transmittance, making them rare in modern use.
Cellulose Triacetate (TAC) Lenses: Offer good optical and processing properties while being lightweight. However, they have poor heat and chemical resistance, and are mainly used in mid-to-high-end eyewear.
Acrylic Lenses (PMMA – Polymethyl Methacrylate Lenses): Highly transparent, easy to process, and low-cost. However, they have poor scratch resistance and low toughness, making them suitable for cost-sensitive applications.

Function options of lens

Vision Correction Lenses

Single Vision Lenses: Designed for individuals with a single vision problem (either myopia or hyperopia). These are the most basic type of lenses.
Progressive Multifocal Lenses: Correct vision at different distances (near, intermediate, and far) within a single lens. Ideal for presbyopic individuals, eliminating the need to switch between multiple pairs of glasses.
Peripheral Defocus Lenses: Create myopic defocus in the peripheral areas of the lens, helping to slow axial elongation and effectively control myopia progression, making them suitable for myopia management in children and teenagers.

Protective Lenses

Blue Light Blocking Lenses: Filter out harmful blue light, reducing eye strain and minimizing the risk of long-term retinal damage. Ideal for individuals who spend extended hours on digital screens.
Photochromic Lenses: Automatically adjust their tint based on light conditions—clear indoors and darken under strong sunlight—protecting the eyes from glare and UV exposure.
Tinted Lenses: Colored through a special dyeing process to meet different visual needs, often used for high-glare environments.
Polarized Lenses: Reduce glare and enhance visual comfort, making them ideal for outdoor activities such as water sports, skiing, and fishing.
