Panoptx Sirocco Sunglasses - Photochromic, Removable Eyecup

The Eyecup is easy to remove and reinsert. The glasses provide pretty good wind protection without the eyecup. The Photochromic change is good. I would have liked them to be tinted a little darker, but that is my ignorance of what to expect from this shade of pink tint, not the manufacturer's fault. They really clarify vision, particularly at dusk when it is harder for me to see. they also included an adjustable fabric "keeper" so I can secure them on my head, dangle them around my neck, or hang 'em from my rear view mirror. The eyecup provides good protection from wind and blowing sand/debris and does not limit my field of vision too much.

I wanted to use these to wear over contact lens in cold or windy conditions, but the fit was so poor that they would be useless for that. Also, the plastic frames feel very flimsy. Even with the STP coupon / discount, I still didn't think they were worth the price and I returned them. It's too bad; I liked the idea of the photochromic lenses.

These glasses are my main stay when flying my Hang Glider. No polarization works best for reading instruments and color contrast works for finding thermals.

With the pads in it feels like you are looking through a tunnel as it reduces peripheral vision somewhat. However, they do block the wind nicely

I live in England where it is normally cloudy and overcast. When the sun comes out everyone is squinting and covering their eyes. These lenses do well in low light and overcast, when the sun does come out they seem to work as advertised. I'm normally on my motorcycle so I don't stop to physically check the photochromic change. The eyecups help keep my eyes from watering with the helmet shield up.
