NCLE Practice Question Guide curve - ANSWER refers to the radius of curvature of the central posterior surface of the lens. It may be expressed in diopters of surface power (D) or in millimeters (mm) of radius or curvature. optical zone - ANSWER the chord diameter over which the base curve extends on the posterior surface of the contact lens, described in millimeters secondary or intermediate curves - ANSWER lies between the base curve and the peripheral curve on the posterior lens surfac...

Which Curve is the Flattest? A) 7.5 mm B) 44.75 D C) 7.6 mm D) 45.50 D - Answer 7.6 mm Inflammation of the Eyelids is Called : A) Palpebritis B) Keratitis C) Conjunctivitis D) Blepharitis - Answer Blepharitis The Base Curve of a Rigid Lens was Ordered at 7.75 mm but Received at 7.85 mm. The Lens is _______ than ordered. A) 0.50 D Flatter B) 0.50 D Steeper C) 1.00 Flatter D) 1.00 Steeper - Answer 0.50 D Flatter The Fairness To Contact Lens Consumers Act of 2003 wa...

optic zone - the central portion of a contact lens which contains the refractive power and generally corresponds to the central corneal cap posterior apecal radius - this term is generally used in reference to spin-cast soft lenses. the curvature of the posterior surface of the lens changes with the refractive power. the radius of curvature is measured at the apex of the posterior surface. steeper base curve - occurs when the posterior radius of curvature is decreased (i.e. 8.4 to 8.1 ...

The first successful contact lenses which were originally molded to conform to the shape of the cornea were known as - Scleral/Haptic lenses Corneal contact lenses: - are the most common design for rigid and gas permeable lenses. The majority of soft lenses fit today are: - semi-scleral A liquid coming in contact with a hydrophilic lens material with a relatively small wetting angle would be likely to: - spread evenly over its surface A contact lens with diameter larger than that of th...
