The primary use of Prentice's rule is that under certain circumstances, the prescribed prism can be obtained without grinding prism into the lenses, by decentering the lenses as worn by the patient.
Where appropriate, prismatic correction can be used, either temporarily or permanently, to relieve symptoms of double vision.

These equations are for healthy weight children and adults. Correction formulae are used for overweight and obese individuals. These corrections for children and adolescents have been debated by S. J. Woodruff, R. M. Hanning, and S. I. Barr in a paper in Obesity Reviews published January 1, 2009. The issue is whether or not the different formulae are actually necessary or possibly even harmful ...
In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia.
Mathematics. The formula for decay correcting is: [1] where is the original activity count at time zero, is the activity at time "t", "λ" is the decay constant, and "t" is the elapsed time. The decay constant is where " " is the half-life of the radioactive material of interest.
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]
In astronomy, the bolometric correction is the correction made to the absolute magnitude of an object in order to convert its visible magnitude to its bolometric magnitude. It is large for stars which radiate most of their energy outside of the visible range.
Race adjustment, also known as race-correction, [1] [2] is the calculating of a result which takes into account race. [1] It is commonly used in medical algorithms in several specialties, including cardiology, nephrology, urology, obstetrics, endocrinology, oncology and respiratory medicine. [1]
