Migraine & Light Sensitivity Lens Technology

TheraShield™

For some people, certain types of light can feel uncomfortable.

TheraShield™ uses selective spectral filtration to reduce selected wavelengths and soften glare for people who experience light sensitivity.

People who experience light sensitivity may find screens, sunlight and fluorescent lighting uncomfortable.

Light Control

Filters selected wavelengths and softens glare to support visual comfort across varied lighting conditions.

Targeted Light Filtration

FL-41-style filtration reduces transmission of selected blue-green wavelengths associated with light sensitivity. Individual experience varies.

Screen and Indoor-Light Comfort

Reduces selected wavelengths and glare from screens and artificial lighting to support visual comfort.

Evening Light Filtering

Reduces selected blue-light wavelengths from screens and indoor lighting during evening use.

TheraShield lenses support visual comfort and are not intended to diagnose, treat, cure or prevent migraine, photophobia or another medical condition. They are not a substitute for professional medical care. Individual experience varies.

The Science of Light Sensitivity

Research has examined how certain blue-green wavelengths may contribute to discomfort for some people with light sensitivity.

TheraShield™ uses FL-41-style spectral filtration to reduce transmission of selected wavelengths while preserving useful visible light.
