My 16 year old watched eclipse with his science class.
I picked up my 11 year old from school 20 minutes before the top of the eclipse. We drove home and watched using shade 10 Omni-View welding lenses with gold colored tint.
It was partly cloudy. Clouds, in fact, helped more than they hurt because you could photograph the eclipsed sun easily. When the sun was out, it was great to use shade 10 lenses, overall it was a great experience.
In my town, the sun was eclipsed approximately by 90 percent. Despite that, it was not dark, at its worst it was dim, like under a heavy cloud cover. That dimness was, however, noticeable.
Shade 14 glasses that the school gave my 16 year old, were way too dim and he could barely see anything.
Overall everyone had a great experience, except the 11 year old got sick with flu or some such.
