TAC polarized lens Suppliers

TAC polarized lens is a high-end polarized product among optical filter elements. It uses multi-layer composite optical materials and precision bonding technology to build the core structure. It integrates a precision optical filter layer inside, which can accurately filter polarized light in a specific direction and effectively suppress glare in scenes such as water and snow. The glare attenuation rate exceeds 90%, while maintaining high transmittance and color authenticity. The lens is specially coated to achieve full-band UV protection (such as UV400 standard), and combined with multi-layer protective coating to improve impact resistance and wear resistance. The products have passed FDA, CE certification and falling ball impact test. This lens is widely used in high-end sunglasses, driving glasses and sports goggles. It is especially suitable for scenes that require high-contrast vision, such as fishing and skiing. Its light and thin design and stable arc control ensure comfort and optical accuracy for long-term wearing.

TAC polarized lens Industry knowledge

TAC polarized lens are not simply tinted lenses; they are constructed from a laminated composite material, with the core polarizing filter layer being the most critical.

TAC stands for Tri-Acetate Cellulose. This lightweight, flexible, and durable material allows TAC polarized lens to maintain excellent optical performance while being lighter and more comfortable to wear. Compared to traditional glass or ordinary plastic lenses, TAC polarized lens are not only more shatter-resistant but also withstand general impact, providing better eye protection.

In addition, the multi-layer construction includes a UV protection layer (reaching UV400 standards), an abrasion-resistant layer, and an impact-resistant coating. These processes ensure that TAC polarized lens offer excellent clarity and durability.

How it works: Reducing glare for a clearer view
In sunlight, strong reflections often occur on water, snow, or wet roads. This glare is called "glare," and it is primarily caused by polarized light in a specific direction.

The core principle of TAC polarized lens is to block horizontally polarized light. The polarizing layer in the lens acts like a set of "blinds," allowing only perpendicular light to enter while blocking out glare caused by reflections.

This filtering method reduces glare by over 90%, resulting in higher visual contrast and more natural, clearer colors. Whether observing schools of fish underwater or discerning the subtle undulations of a snowy slope, you can see more clearly.

How to identify and maintain TAC polarized lens?

Identification method:

Mobile screen test: Place the lens in front of the phone screen and rotate it. If the lens color darkens or even turns black, it indicates polarization.

Overlap test: Overlap two polarized lenses and rotate them. When one of them is rotated 90 degrees, almost no light is transmitted.

Daily care:

Cleaning: Use a dedicated lens cleaning solution and a soft glasses cloth. Avoid wiping with the corners of clothing or rough tissues to avoid scratching the lenses.

Storage: When not wearing, store the lenses in a case to avoid contact with hard objects and keep them dry.

Avoid high temperatures: Avoid prolonged storage in high-temperature environments, such as on a car dashboard, to prevent damage to the lens' performance and lifespan.
