Osi 085



The reason why these "Lucia" glasses were not used before is not the frame but the Rx of the lenses. Almost no spherical strength but fairly strong cylinders with a not very common axis. Most people with astigmatism have what I call a vertical negative cylinder (axis near 0 or near 180) in their glasses. Only a small minority, perhaps one out of five, have horizontal negative cylinders (axis around 90) in their glasses. The "Lucia" glasses once belonged to a lady in this minority category. In short, I never came across a model who could see fairly well through these lovely glasses.
