I would like to know the reason Fresnel Lenses were used in the CV1.
The only reasons I am aware of are to reduce chromatic aberration away from the center of the lens and to improve focus away form the center. Are these the main reasons? Are there other reasons?
It seems to me there should be other reasons because after using the DK2 now for the last month or so at home and the CV1 at work I can say that I would rather have chromatic aberration and the worse focus away from the center of the lenses than putting up with god rays in games such as ED. God rays also make it a challenge for text which tends to have strong contrast (e.g. black on white). Without Fresnel lenses you can always look in the center of the lens which would have no god rays, no chromatic aberration, and good focus but with Fresnel lenses you can't avoid the god rays by looking in the center of the lens.
