Blue hummingbird in Canyon, which I've never before seen here, flies right up & hovers in front of my intense-blue, mountaineering glasses

A hummingbird in Canyon, which I've never before seen here, flies right up & hovers in front of my intense-blue, mountaineering glasses' lenses. Are these blue lenses a sign of food, mating, another hummingbird's plummage or what?


I'd begin my inquiry by exploring the significance of the color of my glasses' lenses.
