Replacement Photochromic POLARISED bifocal reader lenses for your existing BZ Pho Frame.

Lens will change from CAT1 Light grey, pre-dawn or low light to Dark Cat 3 as the sun intensifies and the UV increases.

Polarisation cuts glare, especially on the water.

Available with the magnification options of +1.50, +2.00 and +2.50.

These are ideal for someone who normally wears glasses to read things like: digital screens such as bike computers, GPS's, dashboards and boating or biking instrumentation. Maps, heart rate monitors, watches and mobile phones.
