My journey into myopia control

This blog retraces my personal journey into myopia control and explains why I believe that this is the most important development for optometry that has taken place during my career.

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).
