Disney has issued warnings for Star Wars: The Rise of Skywalker for those who have photosensitive epilepsy.
According to Disney, Star Wars: The Rise of Skywalker contains several sequences with imagery and sustained flashing lights that may affect those who are susceptible to photosensitive epilepsy or have other photo-sensitivities.
Reports suggest photosensitive seizures occur in about 10% of new epilepsy cases in people aged 7-19, though this area of research warrants further study. These seizures are triggered by visual stimuli, such as flashing lights and patterns with repetitive movement.
