Vision with Pediatric Bifocal Contact Lens Wear

Center-distance soft multifocal contact lenses have been shown to slow the progression of myopia,1-5 but practitioners around the world are concerned about the vision produced by soft multifocal contact lens wear in children.

A Novel Soft Radial Refractive Gradient (SRRG) contact lens for myopia control

This experimental design was primarily based on the peripheral retinal blur theory, that E. Smith developed,1 providing an incremental, progressive, refractive change from the central visual axis to peripheral retina, reaching a +2.00D add plus power at about 35 degrees of retinal eccentricity and achieving about +6.00D of addition plus power at the edge of the optical zone (4mm semichord diameter).
