The use of dissimilar progressives in the management of presbyopia

The management of anisophoria with bifocal spectacle correction has always presented a challenging refractive problem. Historically, practitioners have used dissimilar bifocal segments or bicentric grinding to neutralize induced vertical imbalance. We present a method of reducing anisophoria at near point with dissimilar progressive multifocals. By incorporating different progressive designs, anisophoria can be minimized to a tolerable level, based on the dioptric power of lens and progressive lens design.
