An exact algebraic method for designing the model nonastigmatic spherical ophthalmic glasses is given. The method allows us to determine construction parameters of glasses with an assumed back vertex power, which completely fulfil all conditions of correct performance, and takes into account manufacture recommendations. The method consists in solving the system of nonlinear equations by means of software. Calculation of the parameters of nonastigmatic spherical ophthalmic glasses of 65 mm in diameter for positive and negative back vertex powers were designed of organic material CR39 in the most interesting range of vertex powers from 0 to +or-7 with 0.25 D step are presented.
