Development in multifocal contact lens design

Miru 1month multifocal contact lenses (from Menicon) feature a novel approach to lens design based around the physiological differences found in early versus more advanced presbyopia. Here we review both the theory behind the optics and the features that may positively influence both practitioner and wearer experience.

Presbyopia is a rare constant in our changing world, the totally predictable physiological change as we approach our 40s¹ is well understood and the dioptric progression marches on like clockwork year by year.

Our approach to correcting presbyopia has slowly evolved over the centuries, from the very first reading stones of the 13th century to the most sophisticated of 21st century progressive spectacles, multifocal contact lenses and IOLs.
