The human eye can distinguish frame rates above 60 Hz
Evidence from visual psychophysics and display technology indicates that humans can perceive visual differences, flicker, and temporal modulations at frame rates exceeding 60 Hz.
The claim is specific, empirical, and testable. Retrieved literature discussing variable refresh rates, temporal resolution limits, and high-refresh-rate displays demonstrates that humans can detect visual changes, flicker, and reading improvements above 60 Hz.

Discusses variable refresh rates and how changes above 60 Hz can cause perceptible flicker issues for users.

Demonstrates that reading speeds and visual sampling can differ when comparing 60 Hz to much higher refresh rates like 500 Hz.

Notes that the human visual system possesses multiple temporal limits, including specialized fast mechanisms that exceed coarse perceptual thresholds.
