NCLE Practice base curve - 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 - the chord diameter over which the base curve extends on the posterior surface of the contact lens, described in millimeters secondary or intermediate curves - lies between the base curve and the peripheral curve on the posterior lens surface, usually 0.70mm to 1.50mm f...

NCLE Optometry Exam Comprehensive 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 curvat...

abrasion - Answer -rubbing off of the superficial layer accommodation - Answer -adjustment by the eye for seeing different distances, accomplished by changing the shape of the crystalline lens through action of the ciliary muscle acuity - Answer -clearness; measured by the smallest object that can seen at a certain distance adnexa oculi - Answer -accessory structures of the eye, such as lacrimal apparatus and the eye lids against-the-rule astigmatism - Answer -condition in which the steepes...

NCLE basic Exam kit, Questions with accurate answers. 100% Verified. 2022/2023 What is the Secondary/intermediate curve? - The curve on the posterior side of the contact lense between the base curve and peripheral curve. Usually 0.7mm to 1.6mm flatter than the base curve radius. The width is affected by the OZ diameter and peripheral width. What is the peripheral curve? - The outermost curve on the posterior side of the contact lens. It clears the flatter periphery and prevents lens impi...
