Optimum flow-through capability with poor tear composition and quantity

The Percon contact lens has a unique principle whereby the optical zone of a spherical shape changes into an aspherical form. This aspherical shape is a cone with no more obstacles to the ventilation of tear fluid behind the contact lens and which gives the lens a special wearing comfort.
