What's the most appropriate light for eyes?
Define what you mean by appropriate?

Human eyes have three types of colour photoreceptor cells (cone cells), each responding to a different wavelength of light:

Red
Green
Blue

These are also known as the primary colours for that very reason.

There is also a different photoreceptor known as a rod cell which supports vision in low light levels.

The full range of optical wavelengths detected by human eyes is perceived as the rainbow spectrum of colour when the three types of cone receptors detect different intensities of the three primary wavelengths.

Correspondingly, the light given out by our sun is most predominant at the wavelengths perceived as yellow and is the wavelength falling between both red and green wavelength photoreceptor detection producing the largest activated number of cone cells and is therefore the wavelength/colour to which human eyes are most sensitive.
