Ever wonder how those glasses got on your face (88 Pics)

Here we have the RX of the customer I have cut out the personal info for obvious reasons.   This patient has a very strong astigmatism especially in their right eye.  (In optics OD is right and OS is left)  We will want to keep this high RX in mind while manufacturing the lenses.
First we need to select which base curve of lenses we are going to use.  The patient only needs a distance prescriptionas opposed to a bifocal or progressive.
Voilà !!!!   The basic lens we start with is a lot like a hockey puck in size.
Another view
And yet another.
This is a view from inside the lens marker.  We calculate the amount of drop or rise and inset required to line up the RX with the patients pupils.
Here is another view of the marker.  :)
Once the lens is in the correct place, we use a device that has the correct AXIS that we saw on the RX for that eye and use red ink to mark.

After the lens is marked we use a machine to stretch the lens through some "surface saver tape"  its more like a screen protector for your smart phone.  It protects the plus side of the lens while we are going through the next few steps.

We select a specific curved "block" that corresponds with the lens curve we selected earlier.
The block is placed on a wax blocker machine that has melted wax in the cente.  The silver square ring ish thing is full of antifreeze cycling through to chill the wax quickly after it is injected between the block and the lens
