Lens Design and Material
Oxyflex 4F has been designed to produce a balanced periphery with optimum edge lift throughout the range of parameters.The use of high precision manufacturing methods enables a 0.07mm interval to be used for the back optic zone radius. This has the benefit of reducing the range of lenses required for diagnostic evaluation.
