Prototype versions of a telescopic contact lens and complementary pair of ‘wink-sensing’ smart glasses—designed to allow wearers to easily switch between normal and magnified vision—were unveiled earlier this month at the American Association for the Advancement of Science’s (AAAS) annual meeting.
The prototypes hold promise for low-vision or age-related macular degeneration (AMD) patients not only as a nonsurgical solution for a telescopic lens implant, but also as an alternative to traditional low-vision devices such as spectacle-mounted telescopes, according to AOA.
Devised by optics researchers at Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL) in collaboration with others in the United States, the device incorporates a thin reflective telescope inside a 1.55 mm thick scleral lens to produce a magnification of up to 2.8 times.
The telescopic lens works in conjunction with smart glasses that recognize winks and ignore blinks, allowing the wearer to wink his or her right eye for magnification and left eye for normal vision, for instance.
The prototypes remain exactly that, yet researchers hope the devices could enter the market in the next few years and prove helpful to low-vision patients, according to AOA.
Could these devices become mainstream?
More than 3 million Americans have low vision, a number that’s projected to increase to almost 9 million by 2050 with a steadily aging population and prevalence of conditions such as diabetes, AMD, cataracts and glaucoma, according to the National Eye Institute.
Low vision can impact everything in a patient’s life from reading to driving and working, often with few treatment options. That’s why advances in distance-enhancing devices such as these prototype lenses could offer some relief, says Thomas Quinn, O.D., AOA Contact Lens and Cornea Section (CLCS) chair……..
