California Requirements
California Medical Window Tint Documentation
California handles medical sun-protection documentation differently from Arizona and does not use the Arizona MVD exemption process. California law provides specific medical pathways for qualifying sun-screening devices and certain clear UV-filtering materials. Tint-RX evaluates the medical need and provides appropriate physician documentation when supported.
A physician letter does not authorize unrestricted dark tint or override California vehicle-equipment requirements. California does not use Arizona’s MVD application.
Medical sun-screening devices
Vehicle Code §26708(b)(10) covers qualifying devices on the front-seat side windows. The driver or front-seat passenger must possess documentation from a licensed physician and surgeon certifying a medical need for sun protection. A separate optometrist pathway applies to visual conditions. These devices must not be used during darkness.
Under §26708.2, devices must be readily removable. Transparent devices must be green, gray, or neutral smoke with at least 35% luminous transmittance. Patterned devices must have at least 35% open area and comply with louver-size limits. Reflectivity cannot exceed 35% on either surface.
Clear UV-filtering materials
Section 26708(e) addresses clear, colorless, transparent UV-filtering material. It requires at least 88% material light transmission, at least 70% combined glass-and-material transmission, and compliance with the referenced federal glazing standard. The material must enhance UVA protection.
A licensed dermatologist’s certificate documenting the qualifying medical need must be carried by the driver or kept in the vehicle. Material that deteriorates and impairs clear vision must be removed or replaced.
Your evaluation and next steps
Tint-RX provides licensed physician review. Documentation is issued only when medically appropriate and must meet the clinician requirements of the applicable pathway; a general physician letter does not substitute for the dermatologist certificate required under §26708(e).
Follow the instructions accompanying your documentation, keep the required records with you or your vehicle, and confirm the device or material’s compliance with your installer. Tint-RX does not install or certify window materials.

Additional documentation for potential HSA reimbursement
Patients may request an additional Letter of Medical Necessity for medically necessary automotive window film. Tint-Rx offers this letter when clinically appropriate; it is not automatically included with an evaluation, and not every applicant qualifies.
- State-specific tint documentation
- Addresses the applicable state’s medical window-tint requirements.
- Letter of Medical Necessity for HSA purposes
- Explains why recommended window film is medically necessary for the individual patient.
Neither document substitutes for the other. HSA documentation does not authorize tint that violates applicable state law. A letter does not guarantee HSA eligibility or reimbursement, and no particular tint package is automatically eligible.
Please do not email medical records or payment information.
California provides specific options for medically necessary clear UV-protective film and qualifying removable sun screens. A medical certificate does not authorize arbitrary dark permanent windshield or front-side tint. Explore California tint laws.
