Which term describes the pressure points between the eyeglasses frame and the patient's head?

Pantoscopic
Frame Front
Fitting Triangle
Optical Center

The correct answer is: Fitting Triangle

The correct term that describes the pressure points between the eyeglasses frame and the patient's head is indeed the fitting triangle. This concept refers to the three points of contact where the eyewear rests on the face, which typically includes two points on the nose (the pads) and one point on the temples. The fitting triangle is essential in ensuring that glasses fit well and provide comfort, preventing issues such as sliding down the nose or causing pressure marks. Understanding the fitting triangle helps in the adjustment of eyeglasses to ensure they rest correctly on the wearer's face, enhancing both comfort and visual acuity. Proper alignment helps in maintaining the optical center of the lenses in the right position relative to the eyes, thereby optimizing vision while wearing the glasses.
