LENS DE SIGN

Plastic Plus features Avulux, a clinically proven, patented
lens for people living with migraine and light sensitivity.
Avulux follows the latest scientific research on light and
migraine, using a multi-band precision filter technology to
precisely filter up to 97 per cent of the harmful blue, amber
and red light, while allowing in more than 70 per cent
of soothing green light. The lens was validated in an
independent clinical trial, demonstrating clinical and
statistical significance in pain- and light-sensitivity reduction,
compared to a clear placebo lens.
As light sensitivity is a key characteristic of debilitating
migraine attacks, Plastic Plus is proud of Avulux as a
clinically backed solution to help migraine sufferers manage
