Again it's the "Judy" glasses with the extreme cylinder in the left lens: -4.00; c+9.00 o.
The effect of the cylinder can be seen in the tilted image of the background.
The right lens is +2.00; c+0.50 h. A very common Rx.
The "h" stands for "horizontal", indicating that the axis of the cylinder is around 90 degrees.
Here is a lone crystal veil without a lady. The glasses are called "Judy" and were acquired in Germany.
This and the following photos are posted by request.
The left lens has a highly unusual Rx: -4.00; c+9.00 o.
From this vantage point it may look like a prismatic correction but it's not that. It's the effect of the ultra strong cylinder.
The axis is indicated with the "o", meaning either around 45 or around 135. I measure the strength of the lenses with a set of trial lenses so the axis of a cylinder cannot be given precisely.
