Not at all satisfied with their purchase. Their lenses have an incredibly annoying characteristic, that they greatly magnify the reflection of light coming from behind your head, resulting in you always seeing a illuminated frame forming in your lenses, like two vertical lines on the right and left in your field of vision. You can even see it when you have the sun in front of you. It does not have an anti-ghost filter.

Also, while it looks sporty and has non-slip elastic on the arms, as soon as you sweat, the glasses slide down from your nose towards your mouth while walking.

When driving, you definitely have to remove the distractions, and while walking in an urban environment, it is impossible to check intersections just by moving your head, you have to turn your body as well.

Also, the lens is not a "mirror" as described by Skroutz, but I believe this is not Carrera's fault

Bought exactly a year ago. Excellent lens. The eye doesn't get tired. The side shades help with that. They limit vision quite a bit, especially while driving, where attention is needed (that's why I give it four stars). However, they can be removed if someone wants to. In terms of style, it's something original. It doesn't go unnoticed. Also, no need for strings around the neck. The frame is designed to fit tightly around the neck.

Amazing product! It leaves no room for doubt about style! Above all, it is the best for the sun. User-friendly and reliable!
