FIELD: physics, optics.
SUBSTANCE: contact lens is stabilised by development of design parameters of at least one of stabilising zones. Said zone is perfected by description of lens structure parameters by mathematical definitions, simulation of lens structure with the help of model that features the balance of moments of motions and selection of structure proceeding from the results of said simulation. At least one of stabilising zones is defined by one or more parts of variable depth in every stabilising zone. Maximum depth of at least one said stabilising zone makes 0.010-0.060 mm.
EFFECT: better stabilisation.
