| "It is too early 
				to say when exactly human clinical trials for these lenses will 
				begin," a spokeswoman for the Basel-based drugmaker said in an 
				email on Friday.
 "This is a very technically complex process and both sides are 
				learning as we go along. We will provide updates at the 
				appropriate time," she said.
 
 Novartis Chief Executive Joe Jimenez said last year his 
				company's Alcon eye care unit was on track to begin testing in 
				2016.
 
 In 2014, Jimenez said he hoped the lens would be on the market 
				in about five years.
 
 Novartis and Google joined forces two years ago to develop two 
				kinds of "smart" contact lenses: An autofocusing lens for people 
				with presbyopia, or far-sightedness, and another for measuring 
				blood glucose levels in diabetes patients.
 
 The lenses are now being developed with Alphabet Inc.'s life 
				sciences unit Verily, which was carved out from Google in 2015.
 
 Measuring blood sugar via the eye could allow diabetics to stop 
				having to prick their fingers, while an autofocus contact lens 
				would help people whose ability to focus is impaired when their 
				eyes age.
 
 It is unclear when testing for the diabetes lens will start.
 
 Since the partnership with Google was launched in 2014, Alcon's 
				sales have slid and its leadership team has been replaced.
 
 New division head Mike Ball has been tasked with halting the 
				revenue decline in advance of a possible sale of the unit.
 
 But Novartis said that did not bar investment in innovative 
				projects such as the lens effort with Google.
 
 "Advancing innovation such as the smart lens technology, is a 
				key part of Alcon's growth strategy," the spokeswoman said.
 
 "The 'smart lens' technology has the potential to transform eye 
				care and further enhance our pipeline ... in the contact lens 
				and intraocular lens space."
