To help eccentric fixation
FONDA far are magnifying prismatic lenses that, thanks to the synergy of prismatic effect along with magnification, help the eccentric fixation on PRL (Preferred Retinal Locus) identified from a distance.
These new lenses, realized with specific curvature and thickness, generate a prismatic effect that deflects the enlarged image (up to ca. +24%) in the parafoveal area.
The prism’s individual orientation along with the enlargement and the photoselective pigmentation, allows for an increase in depth of field, enhances the posture and boosts visual acuity up to +50%.
FONDA far lenses can be realized with the blue locker photoselective pigmentation to shield the eyes from UVs and blue light, optimizing sight capabilities. All lenses are anti-glare coated.
To obtain a correct prescription, patients must undertake the specific tests designed to identify the patient’s PRL as described in the “FONDA far prescription PROTOCOL”.
FONDA is always available to help the low-vision professionals willing to introduce this innovative aid in their visually impaired patients care. FONDA provides training classes and non stop customer service upon registration on www.fondalens.com.
