PHO Photochromic Bifocal Lens - with assorted frame colour choices

Photochromic Bi Focal Lens — Adapts to Your Light

The PHO frame pairs a lightweight, flexible design with a photochromic bifocal lens that automatically adjusts to changing light conditions — from pre-dawn darkness to full sun intensity. No swapping lenses, no compromises.

How the Lens Works

The lens transitions seamlessly across three light categories as UV levels rise:

• Category 0 — Clear (80–100% light transmission): Ideal for night riding, pre-dawn starts, and low-light or indoor conditions.
• Category 1 — Light tint (43–80% light transmission): Perfect for overcast and cloudy days.
• Category 2 — Medium tint (18–43% light transmission): Good for all but the sunniest days.

Bifocal Magnification Options

Available in three magnification strengths to suit your needs:

• +1.50
• +2.00
• +2.50
