Background:

Decentration is a common issue in ophthalmic lens manufacturing and fitting.
Existing methods for calculating decentration effects can be complex.
Thomson's formulas are used for analyzing obliquely crossed spherocylindrical lenses.

Purpose of the Study:

To present a novel matrix approach for solving decentration problems in ophthalmic optics.
To simplify complex calculations associated with lens decentration.
To provide an alternative derivation for Thomson's formulas.

Main Methods:

Utilized matrix multiplication to model and solve optical decentration.
Applied the matrix formalism to derive established optical formulas.
