Photosensitivity

Also known as: light sensitivityIn Portuguese: Fotossensibilidade

Short definition

Photosensitivity, in the context of virtual reality and screens, is susceptibility to adverse reactions, including epileptic seizures, triggered by flashing lights or visual patterns.

In plain language

The term has several meanings in medicine (it also refers to skin reactions to sunlight), but here it refers to the brain's response to visual stimuli. Its most serious form is photosensitive epilepsy. People with a history of light-triggered seizures should be assessed before using a virtual reality headset.
