I was surprised the ruby performed so badly. I'm not sure whether it was because of the tint or something else.
The prizms definitely performed better though. In terms of the mariens vs dillons, there wasn't enough of a difference based on perceived visual acuity that warrants the massive price difference. The dillons did perform slightly better. Only slightly.
Bear in mind it isn't an exact study. It was just done for fun.
Soooo...abstinence was "just for fun"?
