This is a double-blind cross-over study which showed the incidence of headaches and eye-strain was more than halved by a measure that reduced the amount of light modulation in the 100Hz region.

Yes, there's concrete scientific evidence that flicker causes eye-strain, though it varies between individuals. LCD flicker is caused by the compact fluorescent tubes commonly used as backlights, and presumably LED lighting eliminates this.
