Mother and daughter 049

Esther (left) and Miriam showing how glasses fashion gradually shifted towards larger frames around 1970. The glasses look almost identical but they were made by different companies.
Esther is wearing glasses called "Silvana". If my memory serves me correctly, the Latin word "silva" means "forest". The glasses were made by Rodenstock, renowned for the way they followed the recent trends and mellowed these for the crowds. Glasses like "Silvana" were quite popular in Amsterdam during the late 1960's and early 1970's.
Miriam's glasses are called "Julia" and the name of the optician that sold the glasses is stamped on one of the arms. Note the model's wide eyed look. This is partially caused by the axis of the strong cylinders in the lenses. Unfortunately, the flattering axis seen here is fairly rare. Most lenses in glasses for astigmatism have what I call a vertical (negative) axis, compressing the image of the eye in the vertical direction. I never read an explanation why the vertical axis is far more common than the horizontal axis. Perhaps the followers of this weblog can throw light upon the matter?
My sincere apologies go to Miriam for demolishing some branches and leaves in the background. This was done to achieve a nice "flower power" effect, in tune with the style of the late 1960's and early 1970's!
