ReadEZ Clip-Ons are available in 12 colours (A-L) and two saturations (darkness). The patient simply attaches the clip-ons to their glasses when colour is required.
The colours have been carefully chosen by a team of vision experts to provide the optimum saturation (colourfulness) and transmittance (darkness) to minimise the symptoms of Visual Stress.
The lenses are made of CR39 (the same material as most spectacle lenses) and the clip-on fits most types of spectacle frame.
