How the Lens Technology Works

TheraRead™

TheraRead™ changes spectral transmission and perceived contrast through a selected tint. Tint and intensity should be chosen around wearer comfort and, where appropriate, professional guidance.

Selected-Wavelength Filtering

Reduces selected wavelengths and changes perceived page contrast and glare.

Page Contrast Adjustment

The tint changes perceived contrast between text and its background. Preferences vary by reader.

Tinted Light Transmission

Uses a selected tint to change transmitted light. It does not treat cortical activity or dyslexia.

Tint and Intensity Options

Available in different shades and intensities. Selection should be based on wearer comfort and professional guidance.

About Visual Comfort While Reading

Research has examined coloured overlays and tinted lenses for visual comfort, but findings and individual responses vary.

TheraRead™ changes spectral transmission and perceived contrast. Response varies between wearers.

Some wearers may prefer a particular tint, but these lenses should not be expected to improve reading fluency or comprehension.
