As an eyeglass wearer, I’m one who has had excellent success with safety goggles and never noticed any distortion. Besides the combined wind protection and wide-open ventilation, I like the clear plastic lenses for riding in darkness, and the rigid earpieces which allow me to wear a Take-a-Look rearview mirror on the safety glasses. I virtually never fog, and my worst case, as shown below, was the frosting that occurred from about miles 10 to 14 on my commute starting out at at 0 degrees F and finishing at minus 8. I still had enough clear vision to ride. Note that the frosting happened on the right hand curb side, allowing me to still use the rearview mirror.

A modification that allows the safety glasses to sit comfortably on my face is to wrap Velcro around the nose bridge and attach the Velcro on the glasses to a vertical strip of Velco sewn onto my woolen skull cap. The safety glasses are thus suspended rather than pressing down on my nose. The exhaled warm moist air is directed over my exposed cheeks to keep them warm, but is adequately vented away by the large gap of the open safety goggles. Though the picture shows full face covering, that's only at the beginning of the ride, and I do need to lower the facemask and uncover my nose, but my face is still kept warm by the exhalations. I can easily adjust the position of the mask for various situations to minimize fog and keep warm.
