1.591PC Progressive Polycarbonate Lens

Thinkey Optical's 1.591 PC polycarbonate progressive lens integrates near, intermediate, and distance correction into a single lens, eliminating the need for multiple pairs of glasses. Made from durable, impact-resistant polycarbonate, it stays lightweight and comfortable for all-day wear, while advanced surface optimization ensures smooth power transitions between vision zones with minimal distortion. This lens is available in the following options:

Clear

The standard Clear option delivers seamless multifocal vision correction with the impact resistance and slim profile of 1.591 polycarbonate.

Photo Grey / Brown

This option automatically adjusts tint in response to sunlight, shifting from clear indoors to grey or brown outdoors. Grey preserves true color perception while brown enhances contrast — well suited to outdoor and driving use, without compromising the lens's progressive design.

Blue Cut UV420

This option adds blue-violet light filtering (up to 420nm) to the progressive design, reducing digital eye strain during prolonged screen use while allowing beneficial light through with minimal change to color perception.

Photo Grey / Brown Blue Cut UV420

This option combines both technologies — photochromic tint response and UV420 blue light filtering — for all-day protection as wearers move between screens, indoor environments, and sunlight.
