  1. What is the purpose of 'face form' (wrap) angle in spectacle frame fitting?

    Answer: It curves the frame front to follow the contour of the patient's face

    Face form (wrap) angle describes how the frame front curves to match the natural curvature of the patient's face for better fit and aesthetics.

  2. Which of the following describes a 'slab-off' (bicentric) grind, and when is it used?

    Answer: Prism ground into the lower segment of one lens to correct vertical imbalance in bifocals

    Slab-off grinding removes base-up prism from the reading area of one lens to equalize vertical prism imbalance caused by anisometropia in bifocal wearers.

  3. A patient with a high minus prescription asks for the thinnest possible lenses. Which combination is best?

    Answer: High-index material with a small eye-size frame

    High-index materials have a steeper refractive index (thinner profiles), and smaller frames require less edge thickness for minus lenses.

  4. When using a pupillary distance ruler to measure monocular PD, the optician should align the ruler's zero at:

    Answer: The center of the patient's nose bridge

    The zero (reference point) is placed at the center of the nose bridge, and each pupil center is then measured to that midline.

  5. Which statement about polycarbonate lenses is correct?

    Answer: They are impact-resistant and meet ANSI Z87.1 safety standards

    Polycarbonate is inherently impact-resistant and is the standard material meeting ANSI Z87.1 for safety eyewear; it does require a scratch-resistant coating.

  6. A frame temple that ends with a plastic or metal curve that hooks behind the ear is called a:

    Answer: Comfort cable temple

    A comfort cable temple has a curved or coiled end that hooks behind the ear, providing extra security, commonly seen in sports and children's frames.

  7. To verify that a bifocal segment height has been placed correctly in finished glasses, the optician should measure from:

    Answer: The pupil center to the top of the bifocal segment while the patient wears the frame

    Segment height is verified by measuring from the pupil center (or lower lid margin, per office protocol) to the top of the bifocal segment while the patient wears the fitted frame.
