Porphyria refers to a group of rare disorders caused by problems with the production of heme, a component of hemoglobin. Several types of porphyria cause extreme sensitivity to sunlight. When porphyrins accumulate in the skin, sun exposure can trigger severe burning, blistering, and scarring. The cutaneous forms of porphyria — including PCT, EPP, and CEP — all involve significant photosensitivity.

Symptoms affect people differently. If symptoms interfere with safe driving, stop driving and consult an appropriate clinician. This educational website cannot assess driving fitness, prescribe tint, or determine a safe or legal tint level.
Turn your state guide into a checklist
Symptoms associated with this condition may be relevant to an independent provider's review, but the condition does not automatically qualify. Eligibility, acceptable documentation, and any agency result depend on current state rules and individual clinical review.
Avoid the shortcuts that create confusion
Gather a record that identifies you, the treating professional or facility, and the relevant condition, symptoms, treatment, or surgery. Complete the secure intake and follow current state instructions. An independent provider may approve, deny, or request more information; no documentation or agency result is guaranteed.
