Clear Vision, narrow and discreet frame

First things first: My subjective visual impression is very good, crisp and clear to see everything.
Spring hinges, although very little suspension travel, but this is sufficient.
The first frame makes a solid impression.
The spectacle is more a slimmer profile. This is ideal for my small face. Most other spectacles are much too wide.
I have the glasses in strength +1.5 diopters. Whether the glasses are made of plastic or glass, I can not say. However, they have an impressive thickness of about 4 mm and correspondingly noticeable weight, which is about twice as much as my other cheap glasses with plastic lenses of equal strength. Striking is a very clear visual impression, better than the other cheap plastic lenses.
In this price range I have not seen anything better, strong buy recommendation.
