LED Lighting Flicker and Potential Health Concerns: IEEE Standard PAR1789 Update 

Summary of Biological Effects The obvious biological effects occur: 1) immediately from 2) flicker that is visible. The risks include seizures, and less specific neurological symptoms including malaise and headache. Seizures can be triggered by flicker in individuals with no previous history or diagnosis of epilepsy. The less obvious biological effects occur: 1) from flicker that is invisible 2) after exposure of several minutes.
Invisible flicker health effects have been reported to include headaches and eye-strain.
The table in the Appendix summarizes and categorizes the types of flicker and the biological effects they cause.
