How to correctly measure the inclination angle of glasses
You might have already noticed that when different people wear glasses they are positioned at different places on the face.This is usually caused by the difference in angle of glasses. Correctly adjusting the inclination of glasses when designing and manufacturing process will influence the visual effect, comfort and appearance of the wearer.
This article will explain in detail how to measure the inclination of a pair of glasses?
1. What is the inclination of glasses?
1. What is the inclination of glasses?
The inclination of glasses refers to the angle of the front or temple of the frame on the face. Generally, we can divide it into the following two types:
Nose pad inclination :
Nose pad inclination :
The inclination of the nose pad of the glasses refers to the inclination angle of the nose pad of the glasses relative to the frame of the glasses.
This angle determines how the nose pad contacts the bridge of the wearer's nose. The correct nose pad inclination can effectively disperse the weight of the glasses and reduce the pressure on the bridge of the nose.
The inclination of the temple (Face Form Angle):
The inclination of the temple (Face Form Angle):
This refers to the angle between the temple of the frame and the side of the face.
This angle is related to the stability and comfort of the glasses. The right inclination angle of the temples ensures that the glasses are stably fixed on the bridge of the nose and ears, thus preventing the glasses from slipping off or exerting too much pressure on the face.

2. Common measuring tools
A common tool for measuring the inclination of glasses is the inclination plate.
A tool specifically used to measure the inclination of the frame of glasses. It can help designers and manufacturers ensure that the inclination of the glasses frame meets the design requirements.

3. Case analysis and how to measure?
Recently, we have frequently received feedback from the same customer that the inclination angle of the temples cannot match the design drawings. and it is beyond of tolerance.
In response, our internal production department immediately tested the samples kept in the factory, and the results showed that the samples fully met the requirements. However, the customer still insisted that there was a problem.
Based on this situation, we considered that the customer may have deviations in the measurement method, so we asked the customer to provide photos of the measurement for our reference.
After analysis, we found some common measurement errors:
The picture shows the customer's measurement method:
The following is the measurement method of our eyewear factory production manager:
So what exactly is wrong with the customer that causes the measurement result to be biased?
Position of the glasses frame:
When measuring the inclination, the glasses frame must be in a horizontal position so that accurate inclination data can be obtained. If the frame is tilted, the measurement result will be inaccurate.
Correct use of the inclination plate:
Centre the inclination plate in the frame and make it perpendicular to the edge of the lens (90 degrees).Read the forward angle and the inclination from the inclination plate on the data.
Briefly, the tendency of glasses to slip directly impacts the wearer’s visual experience – in addition to the stability and comfort of their glasses, eyewear, eyeglasses,glasses frame.

So it’s important to make sure you measure and set the angle of your glasses accurately when you’re designing them or making them.
By following this criterion strictly we can yield a better product (close consistency), reduce communication mistakes (close repeatability) for customers due to knowing how the product is made, and likely a better customer experience overall.
