About
RULE OF CONOID - Simulate the "circle of least confusion" on prescription eyeglasses.
This application is based on the rule of the conoid of sturm. Widely used to calculate the prescription glasses when you do not want to totally correct the astigmatism power.
With the application "Rule of Conoid" the ophthalmologist can calculate in a simple and practical way the astigmatism to prescribe in cases of high aniseikonias. The application reduces the amount of prescription of astigmatism, maintaining the accommodative balance and the "circle of least confusion" on the retinal plane.
