As FA and OA have been popularized in various stages of the production system, heavy mental work is extremely increased now. The CFF (critical flicker fusion frequency) measured at the central retina of both eyes has been used widely to evaluate the mental workload. In this paper, we develop the equipment measuring CFF at the central and the peripheral retina (MCFF). The CFFs at the central retina of both eyes, or each eye, show high correlation with each other, as do those at the peripheral retina. But there is a different tendency between the former and the latter. The variation of spectrum of brain waves (α, β, θ, δ) can be estimated from MCFF, except for CFF, at the central retina of both eyes (usual CFF). From these results, it is considered that MCFF proposed can be used to estimate the mental workload more precisely.
