Types of Glasses Lenses: A Practical Guide by KARUSON

Overview of common lens categories

At KARUSON, a premier eyewear factory established in 2010, we categorize the most sought‑after types of glasses lenses into functional families—single‑vision, bifocal, progressive, polarized, photochromic, blue‑light, and specialty materials such as high‑index and polycarbonate. This concise guide helps brands, retailers and buyers choose the right lens technology for comfort, style and performance.

Single‑Vision and Bifocal Lenses

Single‑vision lenses correct a single focal plane—distance or near—and remain the simplest, most common option. Bifocal lenses provide two distinct optical powers with a visible segment for near tasks. KARUSON manufactures both with tight tolerance control and consistent optical clarity across large production runs.

Progressive (No‑Line) Lenses

Progressive lenses deliver a smooth, multi‑distance power gradient without visible lines, ideal for presbyopia and modern lifestyles. Our engineering team supports bespoke progressive designs, customized corridor lengths and rapid prototyping to meet brand specifications.

Polarized and Sunglass Lenses

Polarized lenses dramatically reduce glare from reflective surfaces and are essential for outdoor, driving and sports eyewear. KARUSON integrates polarization, UV400 protection and durable mirror coatings into polarized sunglass lines for superior visual comfort.

Photochromic and Blue‑Light Lenses

Photochromic lenses adapt to changing light conditions for all‑day convenience, while blue‑light filtering lenses protect digital‑screen users from eye strain. We formulate coatings and tints to balance transmission, clarity and wearer comfort for diverse markets.

High‑Index, Polycarbonate and Specialty Materials

High‑index and polycarbonate lenses offer thinner, lighter, and impact‑resistant solutions for stronger prescriptions and active lifestyles. As a vertically integrated OEM/ODM, KARUSON provides material selection, anti‑reflective coatings, scratch resistance and precision logo engraving to elevate your product line.
