Very good, after 1 month of use I eliminated the contact lenses. When you wear them, you have a comfortable field of vision since there is no frame. Also, even though I wipe them with whatever I find in front of me, they don't scratch and don't fog up. The lenses are very clear, nothing compared to the Chinese plastics. The only drawback is that when I look completely sideways, the bridge of my nose enters the field of vision.

Well, I have bought them three or four times, they are nice glasses, comfortable and clear, but I will not buy them again. Within a month of use, they all break at the base of the arm, despite taking good care of them.
