The glasses came quickly with us and fits my 4 year old daughter very well and seems even to be able to fit a number of years, as long as does not get destroyed. She runs around with it at the time in the apartment, because they like it so much. The yellowish field of view you say too much and not obscured as some other glasses do the run. She says it seems as the sun even when it is cloudy, but not aperture it. In action we could not try it, so I can not say anything for fogging of glasses.
