Each filter colour has a Visible Light Transmission (VLT) figure, which indicates the percentage of light passing through the filter. A low value will block more light from entering the eye; a high value allows more light into the eye. You should avoid a VLT% that is too dark for your needs for safety reasons.

The grey filter offers a soothing colour and excellent glare protection.

The premium range consists of three frame styles, Sports Rx Wraparound, Aviator and Retro Rx Wraparound. All of these styles are designed to be worn without prescription spectacles. The Rx styles contain a removable insert which can be taken to an optician to incorporate your prescription.

Please note: Frame images are shown in greyscale, please refer to the colour swatch above as a guide to the tint of these filters.
