This page is intended to demonstrate the effect of light reflection. If this would bothers you, you can consider anti-reflective glass.
The photos below, taken in the kitchen with direct light from a window at 90° to the right on the south side, always show the standard PVC supplied on the left and the anti-reflective glass on the right.
By hovering over the image you turn the light on and off.
If you bought a frame in the past, it was made of glass, nowadays you will only find PVC, the big advantage of PVC is that your frame is light and has a certain flexibility so that it does not break during transport or if it accidentally falls or is knocked over. The disadvantage is that it is not as perfectly flat as glass, so that the curved open surface can stand out when light is reflected.
Nowadays, people move around when viewing a work of art so that they are not disturbed by reflections of light. It is also true that if your work hangs far enough from the windows, you will experience little or no inconvenience. So basically everyone is satisfied with the PVC frame.

Anti-refelective glass
As an experiment, I once used Lucas Creative's anti-reflective glass and compared it to PVC. You will see a remarkable reduction in light reflection, so if you would like anti-reflective glass for framed work, this can be provided.
As mentioned, this is an option that is never actually asked, because people move when viewing a work so that no disturbing reflection is noticed, if that is the case. But if your work is hanging close to a window with direct sunlight, it may be worth considering anti-reflective glass for the frame.
In the photos shown, on the left you see the least favorable situation with PVC and on the right you see the result of the anti-reflective glass from Lucas Creative. Also striking is the effect of a light source on the reflection. The works below were therefore not photographed under ideal lighting conditions, but as they appear in the kitchen with a hanging lamp that is mainly intended to illuminate the table.
