Polarization & Lenses

TALEX does offer polarized prescription lenses. However, currently only in Japan. But we are hoping to be able to offer prescription lenses in the US market in the future.


All our frames are made from durable and flexible nylon, a polymer that is known for its light weight and relatively little “aging” (many plastics degrade over time from exposure to sunlight). It is also skin-friendly and one of the lightest materials available.

Our lenses are made from various different materials. Most of them are CR-39, a type of polycarbonate that is known for its extremely clear visible spectrum, and therefore ideal for eyeglass lenses. CR-39 is widely used in the premium lens industry as it provides an ideal balance of visual qualities and durability.

But the secret is in how we make these lenses. Our patented iodine filter is laminated between two very thin layers of CR-39. Additional coatings make our lenses extremely durable, and quite frankly some of the best polarized lenses in world.


All our products ship free directly from Osaka, Japan.

Orders typically ship within 2 business days directly from our factory in Osaka, Japan, and will arrive in 5-10 business days (sometimes faster).

Please note, COVID delays through shipping carriers due to volume and safety precautions could extend the delivery window.

Expedited delivery is currently not available, as we are already using one of Japan's premier shipping service. But we are working on options to ship from our US headquarters in Portland, Oregon in the future.
