How Prescription Sunglasses Are Made at Eyewear Republic

I’m taking you on a step by step process on
how we get Prescription Polarized lenses into either your favorite sunglasses or some of
the sunglasses that we have at our store. This is the one that Jason chose, but it doesn’t
have the prescription lens, yet. Now, I’m going to take all of the measurements
that I took, accurate to the 1/10th of a millimeter and I’m going to cut them into this frame! In order to get measurements that are 25 times
more accurate than what anybody else can do, I remove the lenses from the sunglasses and
then I add this futuristic looking contraption here. The green squares mean that I’m just far enough
away and now we’re going to take three measurements: Vertex Distance (distance from the lens to
the Cornea) We’re also going to measure: the Pantoscopic
Tilt, and we’re also going to measure: the Wrap
of this frame. We now plug the pupillary distance measurements
accurate to the 1/10th of a millimeter. We also plug in the elevation of the optical
center accurate to the 1/10th of a millimeter. And then we’re going to block the lens so
that the lens is in place while the edges are being cut in the shape is being cut into
the lens. These are the original ready-to-wear lenses
that are polarized green mirror and they have a non-reflective treatment on the inside. And these are the Progressive Polarized Prescription
Sunglasses. They have a +1.25 Diopters at the distance
and then they have a +2.50 reading power at the reading level. They also have a Non-Reflective treatment
on the backside. Look at this! You can’t even tell that they are Prescription! It’s impossible to tell.
