NCLE Test Module 1 with all Correct & 100% Verified
Answers |Latest Version |Guaranteed to Pass
The first successful contact lenses which were originally molded to conform to the shape of the
cornea. ✔Correct Answer-Haptic
The most common design for rigid and gas permeable lenses. ✔Correct Answer-Corneal
Contact Lenses
The majority of soft contact lenses fit today. ✔Correct Answer-Semi-scleral
A liquid coming in contact with a hydrophilic lens material with a relatively small wetting angle
would be likely to: ✔Correct Answer-Spread evenly over its surface
A contact lens with a diameter larger than that of the cornea. ✔Correct Answer-Haptic
A contact lens was ordered with a base curve of 7.85 mm but was received back from the
laboratory with a base curve measuring 7.80 mm. The Base curve of the actual lens is:
✔Correct Answer-0.25 steeper than the lens ordered.
A contact lens has a base curve of 7.50 mm. It's posterior peripheral curve would most likely be:
✔Correct Answer-42.50 D
The secondary curve of a rigid contact lens is generally: ✔Correct Answer-2 to 4 diopters
flatter than the CPC
The term "Haptic Lens" is used in reference to: ✔Correct Answer-Scleral Lens
The CPC of a contact lens measures 7.5 mm radius of curvature. Its power in diopters is:
✔Correct Answer-45.00 D
A soft contact lens demonstrates excessive movement. This may be remedied by: ✔Correct
Answer-A larger diameter lens
The term "sagittal value" refers to: ✔Correct Answer-The vaulting effect of a contact lens
When determining the best lens material to use, what 3 things should be considered?
✔Correct Answer-The patient's working conditions, pre corneal tear film evaluation, full time vs
part time wear
The gas permeability of a CAB lens is largely dependent upon: ✔Correct Answer-The Lens
thickness
