Would new bifocals have helped Picasso?

The wruter is in possession of a flyer from the DeYoung Museum which promotes an upcoming show with Picasso exhibits. The painting serving as a come-on which claims to be a lady's portrait; Her nose seems located such that both eyss seem to be on the same side of the nose. Since I have worn bifocals, I have personally observed such an anomaly if the object I am inspecting falls at the dividing line between the two sections. This is not the first time one has seen artistic effects that some experts attribute to vision defects; apparently Van gogh showed what he actually saw in his "Starry Night", with perhaps a small amount of exaggertion for artistic effext. One should not confuse a painting to a photograph taken with a good camera.
