| Hoya Summit - The design that brought progressive lenses into fashion
 
							
								
									| Prior to Free Form technology, Summit CD was 
									the first progressive lens to make smaller, 
									more fashionable frames possible.
 
 Computers and virtual reality software once 
									designed lenses so advanced they couldn’t be 
									made, because the technology to produce them 
									didn’t exist yet. HOYA developed the Summit 
									family of progressive lenses during this 
									era, including the Summit ECP, and the 
									Summit CD (compressed design), which 
									incorporated the ECP design into smaller 
									frames.
 
 HOYA's patented Integrated Transmittance 
									Control (ITC) Technology utilizes a 3-D 
									virtual computer model to evaluate multiple 
									visual criteria and deliver the clearest, 
									most comfortable vision possible with 
									traditional surfacing technology.
