My doctor says I need to avoid the sun. Can I add dark window tint because of a medical condition?
You may get your physician or optometrist to provide you with a prescription, letter on practitioner’s letterhead, or affidavit stating that there is a physical condition that requires you to have windows tinted darker than Oregon law allows. An affidavit is generally considered to be a legal document that must be notarized. Either the prescription, letter or affidavit and the tint installers certificate must be carried in the vehicle at all times and provided to law enforcement upon request. DMV does not issue permits for darker window tint
