Quick answer
California's medical window tint provision is limited. It allows a removable sun screen or shade device on the front side windows, only with a physician's or optometrist's letter, and only in daylight. It does not allow dark film on the front side windows. ShadedMD can provide the physician's letter for the removable device, but no letter from any service makes dark front film legal in California.

The honest answer about California
Many drivers search for a California medical tint exemption hoping it works the way it does in Florida or Texas. It does not. California's medical provision is limited. It allows a removable sun screen or shade device on the front side windows, only with a physician's or optometrist's letter, and only in daylight. It does not allow dark film on the front side windows.
That means a medical letter in California does not make dark aftermarket film on the driver's and front passenger's windows legal. Any service that suggests otherwise is setting you up for a ticket. ShadedMD would rather tell you the truth up front.

What ShadedMD's certificate can do in California
ShadedMD is a licensed-physician telehealth service that issues signed medical documentation online in 24 to 48 hours for a flat $129, backed by a 30-day money-back guarantee. In California, that documentation serves as the physician's letter that supports the removable sun screen or shade device on the front side windows during daylight.
- Can do: provide a signed letter from a licensed physician documenting your light-sensitive condition, which is what the California provision requires for a removable device.
- Can do: give you a professional, printable document with a Recommendation ID to keep in the vehicle.
- Cannot do: make dark film on the front side windows legal. No letter can, because California law does not provide for it.
- Cannot do: override the daylight-only limitation on the removable device.
If you understand that scope and it fits your needs, ShadedMD is the fastest and most affordable way to get the physician's letter. If you were hoping to install dark front film in California, the letter will not accomplish that, and we want you to know before you pay.
What a removable sun screen means in practice
A removable device is something you can take off the window, such as a clip-on or static-cling shade, rather than film bonded to the glass. The idea is that the driver uses it during daylight, when sun exposure is the problem, and removes it at night, when visibility matters most. Ask your tint shop or auto accessory store about removable options that fit your vehicle, and keep the physician's letter in the car whenever the device is in use.
Because the device comes off, it will not solve every problem that a permanent film solves. Drivers with serious photosensitivity often combine it with UV-blocking clear film where legal, protective clothing, and sunscreen. Our guide to sunscreen vs window tint while driving and our article on whether car window tint blocks UV explain the tradeoffs.
Who California's provision is meant for
The provision exists for people with real light-sensitive conditions: lupus, porphyria, xeroderma pigmentosum, albinism, a history of skin cancer, and severe photophobia from eye or neurological conditions, among others. Preference, privacy, and heat do not qualify. See conditions that may qualify and conditions that usually do not qualify.
ShadedMD's physicians review every case individually. If the doctor cannot document a qualifying condition, you receive a full refund under the 30-day guarantee.
