2. Prism correction - Wikipedia

   en.wikipedia.org/wiki/Prism_correction

   A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. Thus a prism of 1 Δ would produce 1 cm visible displacement at 100 cm, or 1 metre. This can be represented mathematically as: = ⁡ where is the amount of prism correction in prism dioptres, and is the angle of deviation of the light.

4. Prism cover test - Wikipedia

   en.wikipedia.org/wiki/Prism_Cover_Test

   The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]

6. Vertex distance - Wikipedia

   en.wikipedia.org/wiki/Vertex_distance

   Vertex distance is the distance between the back surface of a corrective lens, i.e. glasses (spectacles) or contact lenses, and the front of the cornea. Increasing or decreasing the vertex distance changes the optical properties of the system, by moving the focal point forward or backward, effectively changing the power of the lens relative to ...

7. Fixation disparity - Wikipedia

   en.wikipedia.org/wiki/Fixation_disparity

   Fixation disparity. Fixation disparity is a tendency of the eyes to drift in the direction of the heterophoria. While the heterophoria refers to a fusion-free vergence state, the fixation disparity refers to a small misalignment of the visual axes when both eyes are open in an observer with normal fusion and binocular vision. [1]

8. Subjective refraction - Wikipedia

   en.wikipedia.org/wiki/Subjective_refraction

   Subjective refraction. Subjective Refraction is a technique to determine the combination of lenses that will provide the best corrected visual acuity (BCVA). [1] It is a clinical examination used by orthoptists, optometrists and ophthalmologists to determine a patient's need for refractive correction, in the form of glasses or contact lenses.
