A company called VisionCare has been developing a telescoping contact lens for a few years and is leading the way for US companies.
Optomotrist James Wolffsohn, spokesperson for the British Contact Lens Association, looks forward to one day using technologies like the telescopic lens in clinical practice. “The lens seems an interesting concept to provide optical magnification to the retina when required,” he says. But he adds that there will be challenges in reaching that stage: “It is currently a scleral lens and thick, including rigid mirror elements which are likely to affect corneal physiology and comfort.” Wolffsohn has seen colleagues trial the more established Triggerfish technology to monitor glaucoma and is optimistic about the future of the field. “There are also many other exciting developments in innovative uses of contact lenses,” he says.
