The peripheral visual field through the autofocal

14 April 1978


From a fitting standpoint, the centre-symmetric bifocal contact lens designs represent the simplest approach to fitting presbyopic hard lens patients with multi-focal lenses. The Wesley-Jessen Autofocal can be ordered from PEK photographs, and the lens performs reasonably well with respect to comfort, centration, and tear exchange. This study was designed to determine empirically if the Autofocal lens design could produce undesirable peripheral field restrictions. No significant predictable field changes were observed in the seven subjects tested in this study. This lens cannot, therefore, be contra-indicated on the basis of altering peripheral form detection.
