How do you measure a progressive lens?
- A.
Measure from the bottom of the frame to bottom eyelid.
- B.
Measure from center of nose to center of pupil.
- C.
Measure from bottom of lens to center of the pupil.
- D.
Measure from pupil center to pupil center.
Correct Answer
C. Measure from bottom of lens to center of the pupil.Explanation
To measure a progressive lens, you need to measure from the bottom of the lens to the center of the pupil. This measurement is important because progressive lenses have a gradual change in prescription power from the top to the bottom, so the measurement helps ensure that the correct prescription is aligned with the wearer's pupil. By measuring from the bottom of the lens, you can accurately determine the placement of the progressive power in the lens.Rate this question:

What is the "B" measurement?
- A.
The diagonal measurement of the lens.
- B.
The measurement from pupil to pupil.
- C.
The vertical measurement of a lens.
- D.
The horizontal measurement of a lens.
Correct Answer
C. The vertical measurement of a lens.Explanation
The "B" measurement refers to the vertical measurement of a lens. This means that it is the distance from the top to the bottom of the lens. It is important to know this measurement when fitting eyeglasses or contact lenses to ensure that they properly cover the vertical area of the eye and provide clear vision.Rate this question:

What does PD stand for?
- A.
Physical Dimension.
- B.
Pupillary Dimension.
- C.
Prescribed Distance.
- D.
Pupillary Distance.
Correct Answer
D. Pupillary Distance.Explanation
PD stands for Pupillary Distance. Pupillary Distance refers to the distance between the centers of the pupils of the eyes. It is an important measurement used in the fitting of eyeglasses or contact lenses. Knowing the PD helps to ensure that the lenses are properly aligned with the eyes, which is crucial for optimal vision correction.Rate this question:

What type of lens material do you recommend for a -7.00 sph. prescription?
- A.
Hi-index
- B.
Polycarbonate.
- C.
Mid-index
- D.
Glass
Correct Answer
A. Hi-indexExplanation
Hi-index lens material is recommended for a -7.00 sph. prescription. Hi-index lenses are made from a material that has a higher refractive index, meaning they can bend light more efficiently. This allows for thinner and lighter lenses, making them more comfortable to wear. Hi-index lenses are especially beneficial for high prescriptions like -7.00 sph. as they reduce the thickness and weight of the lenses, improving the overall aesthetics and comfort for the wearer.Rate this question:

What type of lens material would you choose to go into a three piece drill mount?
- A.
Mid-index material
- B.
Glass.
- C.
Hi-index 1.70
- D.
Trivex
- E.
Correct Answer
D. TrivexExplanation
Trivex is the recommended lens material for a three-piece drill mount. Trivex is a lightweight material that offers excellent impact resistance and durability, making it suitable for drill mount frames. It also provides good optical clarity and is resistant to scratches. Additionally, Trivex has a lower density than glass, making it more comfortable to wear. Mid-index material, Hi-index 1.70, and glass may not be as suitable for a drill mount due to factors such as weight, fragility, and potential for cracking during the drilling process.Rate this question:

- A.
16 mm
- B.
23 mm
- C.
26
- D.
29
Correct Answer

Which of these frame materials is the lightest for frames?
- A.
Titanium
- B.
Nickel
- C.
Stainless steel
- D.
Monel
Correct Answer
A. TitaniumExplanation
Titanium is the lightest frame material among the options given. It is known for its high strength-to-weight ratio, making it a popular choice for various applications, including frame construction. Titanium frames are lightweight, durable, and resistant to corrosion, making them ideal for eyeglasses or other products where weight is a crucial factor. Nickel, stainless steel, and monel are comparatively heavier materials and are not as lightweight as titanium.Rate this question:

What frame features would best suite a person with a round face?
- A.
Square angles and lines.
- B.
Deep vertical -mid temple
- C.
Rimless, high temple - smaller verses larger
- D.
Angles, sharp corners
Correct Answer
D. Angles, sharp cornersExplanation
Angles and sharp corners would best suit a person with a round face because they can help create the illusion of more defined facial features and add structure to the face. These frame features can help balance out the softness of a round face shape and make it appear more angular. By choosing frames with angles and sharp corners, the face can be visually elongated and the overall look can be more flattering.Rate this question:

When troubleshooting adjustments for progressive lens wearers always?
- A.
Check the fit of the frame.
- B.
Check the seg height measurement.
- C.
Check the prescription.
- D.
Check the PD.
- E.
All of the above.
Correct Answer
E. All of the above.Explanation
The correct answer is "All of the above." When troubleshooting adjustments for progressive lens wearers, it is important to check all of these factors. Checking the fit of the frame ensures that the glasses are comfortable and properly positioned on the wearer's face. Checking the seg height measurement ensures that the progressive lens is positioned correctly for optimal vision. Checking the prescription ensures that the lenses are accurately made according to the wearer's visual needs. Checking the PD (pupillary distance) ensures that the lenses are aligned properly with the wearer's eyes. Considering all of these factors is crucial in troubleshooting adjustments for progressive lens wearers.Rate this question:
