Have you ever heard of Pantoscopic Tilt?
Pantoscopic Tilt is an important measurement for Progressive Lenses.
Have you ever noticed that your vision completely gets distorted whenever you move your eyeglasses either this way or whenever they move down this way?
That is because of a measurement called the Pantoscopic Tilt. It's a measurement that when taken and then optimized through your prescription (lenses), it can actually enhance your vision and make you see so much better.
The reason is because not everybody's ears are at the same elevation. Sometimes, some people's ears are a little bit higher and sometimes, some people's ears are just a little bit lower.
Pantoscopic tilt measurements are actually taken to the 0.1 degrees in accuracy. This measurement can adjusted on your frames by adjusting it from the temple. My preferred method is adjusting them right here at the temple where it connects the temple to the front (of the frame).
I will either move the temple down or I will move the temple up in this direction. By lowering the temple, you're going to add to the Pantoscopic Tilt in the form of degrees because this is the fulcrum and the this angle here is what creates the Pantoscopic Tilt measurable to the 0.1 degrees in accuracy.
There's a few other ways to increase or decrease the Pantoscopic Tilt, but you're not going to get as much Bang for Your Buck in movement than with the hinge.
In the past, before the lenses could ever be optimized for Pantoscopic Tilt the rule of thumb used to be to have your eyeglasses fit around 8 to 12 degrees.
You would not want them to be very flat relative to the eye. You always wanted them to have a little bit of an angle. So that slope of 8 to 12 degrees was excellent.
Now the ideal 8 to 12 degrees (of Pantoscopic Tilt) is more like a rule of thumb, not necessarily a "have to" or a deal breaker because the lenses can compensate for that.
When you're having trouble seeing with your eyeglasses, the Pantoscopic Tilt is always one of the first troubleshooting techniques that you want to go to and just to have it checked to make sure that the intended Pantoscopic Tilt is actually still on the frame. But if it's been misaligned, it can always be adjusted and put back into the original place that you were measured in.
The dilemma with other optical shops is that a lot of them don't even measure it (Pantoscopic Tilt). And most opticals couldn't even measure it even if they wanted to.
Most opticals are only worried about the frame inventory, what their margins are on those frames, and they completely drop the ball on the quality of your optics.
You have to start demanding more. You have to start expecting better optics. It's the only way that you 're going to push more opticals and opticians to care about the products that they put out.
Let me show you how I measure it. I use digital equipment that when I set this piece (clip) on, these little black and white squares are going to be detected by the camera and the digital software is going to take all the measurents. Not just Pantoscopic Tilt, but a myriad of others so that your eyeglasses can be absolutely perfect.
My question to you is, "Have you ever heard of anybody mentioning Pantoscopic Tilt?". That is a question that I feel you should quickly run to the nearest optical to quiz them to see if they are up to date!
Thank you for watching this video and I hope to bring you lots more to make you aware of what is necessary to give you perfect lenses.
Have a good day!
